| بسم الله الرحمن الرحيم السلام عليكم ورحمة الله | |
| 2 | |
| 00:00:10,440 --> 00:00:15,960 | |
| وبركاته محاضرة الأسبوع التاسع راح نكمل موضوع | |
| 3 | |
| 00:00:15,960 --> 00:00:19,940 | |
| anatomy and physiology of the cranial nerves الجزء | |
| 4 | |
| 00:00:19,940 --> 00:00:24,900 | |
| الأول من محاضرة الأسبوع التاسع راح نتكلم بالتفصيل | |
| 5 | |
| 00:00:24,900 --> 00:00:29,600 | |
| الممل عن anatomy and physiology of the facial | |
| 6 | |
| 00:00:29,600 --> 00:00:34,990 | |
| nerve. أهم عصب لكم في موضوع cranial nerves هو العصب | |
| 7 | |
| 00:00:34,990 --> 00:00:40,990 | |
| السابع facial nerve facial | |
| 8 | |
| 00:00:40,990 --> 00:00:44,670 | |
| nerve, it | |
| 9 | |
| 00:00:44,670 --> 00:00:48,870 | |
| is a mixed nerve, it is a mixed nerve which | |
| 10 | |
| 00:00:48,870 --> 00:00:57,600 | |
| contains motor, sensory, and parasympathetic functions | |
| 11 | |
| 00:00:57,600 --> 00:01:02,920 | |
| أو fibers. هاي هو دي ال mix nerve عشر تلاف وتسعمية | |
| 12 | |
| 00:01:02,920 --> 00:01:09,670 | |
| وخمس وسبعين. خلصنا السابق العصب الخامس اللي هو الـ | |
| 13 | |
| 00:01:09,670 --> 00:01:13,490 | |
| Trigeminal nerve. دلوقت راح اتكلم على Facial nerve | |
| 14 | |
| 00:01:13,490 --> 00:01:17,970 | |
| Facial nerve اللي هو العصب السابع. عصب السابع | |
| 15 | |
| 00:01:17,970 --> 00:01:22,230 | |
| Facial nerve, it is mixed nerve, contains motor | |
| 16 | |
| 00:01:22,230 --> 00:01:27,250 | |
| sensory and parasympathetic fibers. يوم اتكلمت على | |
| 17 | |
| 00:01:27,250 --> 00:01:30,950 | |
| Trigeminal nerve, قلتلكوا Trigeminal nerve, it is | |
| 18 | |
| 00:01:30,950 --> 00:01:35,310 | |
| more important than sensory nerve. اليوم راح اتكلم | |
| 19 | |
| 00:01:35,310 --> 00:01:40,730 | |
| على Facial nerve, it is more important as motor | |
| 20 | |
| 00:01:40,730 --> 00:01:44,070 | |
| nerve، عشان هي مهم إلكوا في العلاج الطبيعي، موضوع | |
| 21 | |
| 00:01:44,070 --> 00:01:51,110 | |
| facial nerve، لإنه عصب حركي أكتر ما هو حسيه، هو في | |
| 22 | |
| 00:01:51,110 --> 00:01:57,110 | |
| خليط الأنسجة، لكن هو more important as motor nerve | |
| 23 | |
| 00:01:57,110 --> 00:02:01,730 | |
| than sensory and than parasympathetic functions. | |
| 24 | |
| 00:02:02,370 --> 00:02:06,550 | |
| what's the root of a facial nerve? اتفقنا ان ال | |
| 25 | |
| 00:02:06,550 --> 00:02:11,070 | |
| facial nerve emerges بخرج من ال lower part of the | |
| 26 | |
| 00:02:11,070 --> 00:02:16,130 | |
| pons, between the pons and medulla oblongata. بخرج | |
| 27 | |
| 00:02:16,130 --> 00:02:22,230 | |
| as a two root, اللي هو كام root؟ two root. large | |
| 28 | |
| 00:02:22,230 --> 00:02:31,100 | |
| root, large root بيكون اللي هو motor facial, motor root | |
| 29 | |
| 00:02:31,100 --> 00:02:37,000 | |
| facial motor root, is purely motor nerve, supply all | |
| 30 | |
| 00:02:37,000 --> 00:02:42,360 | |
| the muscle of expression, facial expression. second | |
| 31 | |
| 00:02:42,360 --> 00:02:48,140 | |
| root, small root, small root بيسموه nerve | |
| 32 | |
| 00:02:48,140 --> 00:02:53,880 | |
| intermediates, nerve intermediates, contains sensory | |
| 33 | |
| 00:02:53,880 --> 00:02:59,900 | |
| and parasympathetic fibers. يبقى كمان مرة ال facial | |
| 34 | |
| 00:02:59,900 --> 00:03:05,370 | |
| nerve بخرج من ال .. ال ventral surface of the pons | |
| 35 | |
| 00:03:05,370 --> 00:03:09,390 | |
| في ال lower part of the pons, between the pons and | |
| 36 | |
| 00:03:09,390 --> 00:03:14,730 | |
| medulla oblongata, as two root, large root, facial | |
| 37 | |
| 00:03:14,730 --> 00:03:20,390 | |
| motor nerve, و small root يعتبر intermedius nerve | |
| 38 | |
| 00:03:20,390 --> 00:03:25,210 | |
| اللي فيه sensory و parasympathetic fibers. sensory | |
| 39 | |
| 00:03:25,210 --> 00:03:32,710 | |
| و parasympathetic fibers هي عندي ال lower part of | |
| 40 | |
| 00:03:32,710 --> 00:03:37,950 | |
| the pons. بخرج منها large root. أنا برسم على ال | |
| 41 | |
| 00:03:37,950 --> 00:03:45,350 | |
| left side, large root اللي هو motor facial nerve, و | |
| 42 | |
| 00:03:45,350 --> 00:03:50,590 | |
| small root, nerve intermediates, nerve intermediates | |
| 43 | |
| 00:03:50,590 --> 00:03:55,030 | |
| اللي علاقة بال sensation و هي parasympathetic | |
| 44 | |
| 00:03:55,030 --> 00:03:59,650 | |
| function, sensory and parasympathetic function. | |
| 45 | |
| 00:04:04,790 --> 00:04:11,850 | |
| nuclei of the facial nerve, حسب ال function, فيه | |
| 46 | |
| 00:04:11,850 --> 00:04:17,450 | |
| nuclei. اتفاقنا main function is motor function. | |
| 47 | |
| 00:04:17,450 --> 00:04:23,750 | |
| يبقى موجود عندي facial motor nerve, facial motor | |
| 48 | |
| 00:04:23,750 --> 00:04:29,590 | |
| nucleus, فيه موجودة facial motor nucleus. تنجسم | |
| 49 | |
| 00:04:29,590 --> 00:04:35,040 | |
| جسمين. هذه ال facial motor nucleus الها dorsal part | |
| 50 | |
| 00:04:35,040 --> 00:04:44,340 | |
| و ventral part. هي نرسمها. هذه تعتبر facial motor | |
| 51 | |
| 00:04:44,340 --> 00:04:57,040 | |
| nucleus of facial nerve, تمام. الها جزئين جزء دورسل | |
| 52 | |
| 00:04:57,040 --> 00:04:59,360 | |
| وجزء | |
| 53 | |
| 00:05:01,570 --> 00:05:10,070 | |

| 00:05:14,890 --> 00:05:19,730 | |
| upper part | |
| 56 | |
| 00:05:19,730 --> 00:05:28,670 | |
| of the face. يبقى الدورسل nucleus بتاعة الموتور | |
| 57 | |
| 00:05:28,670 --> 00:05:34,410 | |
| مسئول عن أي جزء؟ upper part of the face يعني upper | |
| 58 | |
| 00:05:34,410 --> 00:05:38,250 | |
| quadrant of the face. يقول لو غمضت عيني مين حرك | |
| 59 | |
| 00:05:38,250 --> 00:05:44,170 | |
| لعين؟ هذا ال dorsal part. دكتور ايه اضحك شيء عن | |
| 60 | |
| 00:05:44,170 --> 00:05:46,810 | |
| الامتحان و ماعجبك و اشرحها الطالب او طالب يعمل | |
| 61 | |
| 00:05:46,810 --> 00:05:51,800 | |
| بتمها زيك حرك مش ماجبهممش هنجيبهم. يبقى ان انا حركت | |
| 62 | |
| 00:05:51,800 --> 00:05:55,200 | |
| ال lower quadrant of the face المسئول عنه ال lower | |
| 63 | |
| 00:05:55,200 --> 00:06:00,720 | |
| quadrant اللي هو ventral nucleus. المسئول عن ايه ال | |
| 64 | |
| 00:06:00,720 --> 00:06:04,140 | |
| lower part | |
| 65 | |
| 00:06:05,060 --> 00:06:08,780 | |
| of the face. من ناحية انا بتكلم عن ال motor من | |
| 66 | |
| 00:06:08,780 --> 00:06:14,480 | |
| ناحية ايه motor. يبقى كمان مرة facial motor nucleus | |
| 67 | |
| 00:06:14,480 --> 00:06:20,160 | |
| الها two part, dorsal part and ventral part. ال | |
| 68 | |
| 00:06:20,160 --> 00:06:25,340 | |
| dorsal part مسئول عن مين؟ عن ال upper quadrant of | |
| 69 | |
| 00:06:25,340 --> 00:06:29,060 | |
| the face. ال ventral part مسئول عن مين؟ lower | |
| 70 | |
| 00:06:29,060 --> 00:06:32,560 | |
| quadrant of the face. وين موجودة دي ال nucleus؟ | |
| 71 | |
| 00:06:32,560 --> 00:06:36,300 | |
| موجودة في ال pons. موجودة وين؟ في ال pons. إيش | |
| 72 | |
| 00:06:36,300 --> 00:06:41,300 | |
| وظيفتها؟ supply the facial muscles. لو أتكلم على ال | |
| 73 | |
| 00:06:41,300 --> 00:06:46,540 | |
| lower quadrant ببطرق إلى ال ventral part. upper | |
| 74 | |
| 00:06:46,540 --> 00:06:52,120 | |
| quadrant of the face, dorsal part. ثمانة في عندي | |
| 75 | |
| 00:06:52,950 --> 00:06:57,730 | |
| Superior Salivary Nucleus, Superior Salivary | |
| 76 | |
| 00:06:57,730 --> 00:07:02,870 | |
| Nucleus. هذه لها علاقة بال Parasympathetic function. | |
| 77 | |
| 00:07:02,870 --> 00:07:10,630 | |
| Secretomotor. بتغديلنا submandibular and sublingual | |
| 78 | |
| 00:07:10,630 --> 00:07:15,190 | |
| salivary glands, عن طريق branch من ال facial nerve | |
| 79 | |
| 00:07:15,190 --> 00:07:21,600 | |
| اسمه chorda tympani nerve. كوردة تمبني نيرف. و بتغدين ال | |
| 80 | |
| 00:07:21,600 --> 00:07:26,500 | |
| glands of the palate, nose. لاخرم ال gland | |
| 81 | |
| 00:07:26,500 --> 00:07:32,880 | |
| nasopharynx عن طريق عصب اسمه GSPN, greater | |
| 82 | |
| 00:07:32,880 --> 00:07:37,800 | |
| superficial petrosal nerve. اذا ذكروا لما نروح | |
| 83 | |
| 00:07:37,800 --> 00:07:42,100 | |
| المطبخ, نقطع بصل, ايش بيصير حالتنا؟ شلش, بيصير حالتنا | |
| 84 | |
| 00:07:42,100 --> 00:07:48,010 | |
| في شلش, بندمع و بنف و حلق صعبة. بتكون الوضع هنا من | |
| 85 | |
| 00:07:48,010 --> 00:07:53,010 | |
| البصل, مين بشتغل هنا؟ الـ Parasympathetic fibers | |
| 86 | |
| 00:07:53,010 --> 00:07:57,270 | |
| بتاعة مين؟ ال facial nerve. عن طريق أي نوكلياس؟ | |
| 87 | |
| 00:07:57,270 --> 00:08:01,230 | |
| superior salivary nucleus. وظيفته ايه؟ | |
| 88 | |
| 00:08:01,230 --> 00:08:07,590 | |
| Parasympathetic. ال نوكلياس التالتة, solitary nucleus | |
| 89 | |
| 00:08:07,590 --> 00:08:14,530 | |
| موجودة في الميدالة أبلانقاتا. علاقة بماذا؟ علاقة | |
| 90 | |
| 00:08:14,530 --> 00:08:18,130 | |
| بالـ sensory function، ومن ضمن الـ sensory | |
| 91 | |
| 00:08:18,130 --> 00:08:24,310 | |
| function, taste، sensation from the anterior to | |
| 92 | |
| 00:08:24,310 --> 00:08:29,930 | |
| third of the tongue. يعني ال facial nerve مسئول عن | |
| 93 | |
| 00:08:29,930 --> 00:08:34,950 | |
| حاسة التذوق لوين؟ لل tongue. من أي جزء من ال | |
| 94 | |
| 00:08:34,950 --> 00:08:38,630 | |
| anterior to third of the tongue. يبقى ال taste | |
| 95 | |
| 00:08:38,630 --> 00:08:43,370 | |
| sensation from the anterior to third of the tongue | |
| 96 | |
| 00:08:43,370 --> 00:08:48,310 | |
| اللي بيحس فيها هو ال facial nerve, عن طريق عصب اسمه | |
| 97 | |
| 00:08:48,310 --> 00:08:50,750 | |
| نفس الشيء كمان, chorda tympani nerve. هو chorda | |
| 98 | |
| 00:08:50,750 --> 00:08:55,470 | |
| tympani nerve.و أي نوكلياس؟ solitary nucleus. وين | |
| 99 | |
| 00:08:55,470 --> 00:08:58,250 | |
| موجودة ال solitary nucleus؟ في مضلة او بلانجاتا | |
| 100 | |
| 00:08:58,250 --> 00:09:00,390 | |
| احنا قولنا فيه exception. مع ان ال facial nerve | |
| 101 | |
| 00:09:00,390 --> 00:09:03,510 | |
| المفروض يكون في ال pons. تلاحظوا superior salivary | |
| 102 | |
| 00:09:03,510 --> 00:09:06,990 | |
| في ال pons. و ال motor nucleus في ال pons. لكن ال | |
| 103 | |
| 00:09:06,990 --> 00:09:10,830 | |
| solitary nucleus موجودة وين؟ في مضلة او بلانجاتا | |
| 104 | |
| 00:09:10,830 --> 00:09:14,410 | |
| لأنها مسئولة كمان عن العصب التاسع و مسئولة عن من | |
| 105 | |
| 00:09:14,410 --> 00:09:21,600 | |
| عن العصب العاشر. functions of the facial nerve. ايش | |
| 106 | |
| 00:09:21,600 --> 00:09:25,720 | |
| وظيفة ال facial nerve? اول function, it is the main | |
| 107 | |
| 00:09:25,720 --> 00:09:33,760 | |
| function, motor, motor, motor function, motor function | |
| 108 | |
| 00:09:33,760 --> 00:09:40,240 | |
| وظيفتها ال motor اللي هي supply the muscles of | |
| 109 | |
| 00:09:40,240 --> 00:09:47,160 | |
| facial expression. لها علاقة بالموتور | |
| 110 | |
| 00:09:47,160 --> 00:09:52,120 | |
| facial expression. ثاني, parasympathetic function | |
| 111 | |
| 00:09:52,120 --> 00:09:57,540 | |
| to all glands of head. لمين؟ submandibular | |
| 112 | |
| 00:09:57,540 --> 00:10:02,670 | |
| sublingual and lacrimal glands. Except Parotid | |
| 113 | |
| 00:10:02,670 --> 00:10:05,950 | |
| glands. ما بتغدى ال Parotid gland. ال Parotid gland | |
| 114 | |
| 00:10:05,950 --> 00:10:10,470 | |
| بتاخد عن طريق ال Glossopharyngeal nerve. العصب | |
| 115 | |
| 00:10:10,470 --> 00:10:16,450 | |
| التاسع. يبقى facial nerve مسئول عن كل ال salivary | |
| 116 | |
| 00:10:16,450 --> 00:10:21,650 | |
| glands مع دق اوتك أو ال Parotid gland بتاخد من | |
| 117 | |
| 00:10:21,650 --> 00:10:26,690 | |
| Glossopharyngeal nerve. ثلاثة مسئول عن sensory from | |
| 118 | |
| 00:10:26,690 --> 00:10:33,190 | |
| skin of the external auricle و tympanic membrane. بغض | |
| 119 | |
| 00:10:33,190 --> 00:10:36,990 | |
| نظر من الأذن و من طابلة الأذن tympanic membrane و أهم | |
| 120 | |
| 00:10:36,990 --> 00:10:42,930 | |
| شيء مسئول عن ايه؟ taste sensation from the anterior | |
| 121 | |
| 00:10:42,930 --> 00:10:48,220 | |
| to third of the tongue. نطبق على نقلي, ITest | |
| 122 | |
| 00:10:48,220 --> 00:10:52,020 | |
| sensation بتاعة الانترال توترد of the tongue. مسئول | |
| 123 | |
| 00:10:52,020 --> 00:10:58,480 | |
| عنها مين؟ Solitary nucleus. Sensory of skin تبع ال | |
| 124 | |
| 00:10:58,480 --> 00:11:02,740 | |
| external auricle و ال membrane مسئول عنها. تنبانك | |
| 125 | |
| 00:11:02,740 --> 00:11:06,120 | |
| ممبران مسئول عنها كمان Solitary nucleus. الـ | |
| 126 | |
| 00:11:06,120 --> 00:11:08,980 | |
| Parasympathetic Function بتاعته لـ glands, salivary | |
| 127 | |
| 00:11:08,980 --> 00:11:13,000 | |
| glands. Superior Salivary Nucleus. الـ Motor Function | |
| 128 | |
| 00:11:13,000 --> 00:11:19,180 | |
| اللي هي Motor Nucleus of Facial Nerve, تنقسم لقسمين | |
| 129 | |
| 00:11:19,180 --> 00:11:25,490 | |
| Ventral Part and Dorsal Part. و ventral part بياخد a | |
| 130 | |
| 00:11:25,490 --> 00:11:28,790 | |
| أو مسئول عن a. ال ventral part مسئول عن ال lower | |
| 131 | |
| 00:11:28,790 --> 00:11:32,830 | |
| quadrant of the face. lower quadrant of the face و | |
| 132 | |
| 00:11:32,830 --> 00:11:36,670 | |
| dorsal nucleus مسئول عن upper quadrant of the face. | |
| 133 | |
| 00:11:36,670 --> 00:11:44,350 | |
| نتكلم على intracranial course of the facial nerve. | |
| 134 | |
| 00:11:44,350 --> 00:11:48,690 | |
| ال intracranial course of facial nerve. the facial | |
| 135 | |
| 00:11:48,690 --> 00:11:54,030 | |
| nerve emerges from the lower border of the pons، | |
| 136 | |
| 00:11:54,030 --> 00:11:58,250 | |
| بخرج من أين؟ من ال lower border بتاع ال pons، بعد | |
| 137 | |
| 00:11:58,250 --> 00:12:02,810 | |
| هي بيمر في cerebellopontine angle، يوم ما شرحتلكوا | |
| 138 | |
| 00:12:02,810 --> 00:12:05,850 | |
| العصب الخامس، اتكلمنا عن ال cerebellopontine | |
| 139 | |
| 00:12:05,850 --> 00:12:11,050 | |
| angle، بيمر في العصب الخامس والسبع والثامن، بعد هي | |
| 140 | |
| 00:12:11,050 --> 00:12:16,980 | |
| بيفوت لل internal auditory meatus. بيمور وين؟ في | |
| 141 | |
| 00:12:16,980 --> 00:12:22,400 | |
| facial canal أو fallopian canal. ماتخربطوش؟ في | |
| 142 | |
| 00:12:22,400 --> 00:12:25,480 | |
| fallopian tube. حد يكتبلي fallopian tube. fallopian | |
| 143 | |
| 00:12:25,480 --> 00:12:29,760 | |
| tube. هذه موجودة فقط عند ال female. بتربط ال uterus | |
| 144 | |
| 00:12:29,760 --> 00:12:35,320 | |
| مع ال ovary. قناة بين من ومن؟ بين الرحم ال uterus و | |
| 145 | |
| 00:12:35,320 --> 00:12:40,510 | |
| ال ovary و المبايض. fallopian canal موجود عند المال | |
| 146 | |
| 00:12:40,510 --> 00:12:48,570 | |
| والفمال. اسمها facial canal أو اسمها internal | |
| 147 | |
| 00:12:48,570 --> 00:12:52,970 | |
| auditory canal. موجودة في الـ petrostemporal bone. | |
| 148 | |
| 00:12:54,480 --> 00:12:59,480 | |
| أثناء مروره في ال facial canal, ال facial nerve | |
| 149 | |
| 00:12:59,480 --> 00:13:02,900 | |
| بيعطينا three branches. راح نتكلم عنهم بعد هيك. | |
| 150 | |
| 00:13:02,900 --> 00:13:06,940 | |
| finally, it exit from stylo-mastoid foramen. وفي | |
| 151 | |
| 00:13:06,940 --> 00:13:11,280 | |
| النهاية بخرجلنا من الخلف من stylo-mastoid foramen. | |
| 152 | |
| 00:13:11,280 --> 00:13:21,370 | |
| هي اندي تابع معايا. خرج ال facial nerve من lower | |
| 153 | |
| 00:13:21,370 --> 00:13:24,470 | |
| border of the pons, between the pons and medulla | |
| 154 | |
| 00:13:24,470 --> 00:13:33,110 | |
| oblongata. مروين في cerebellopontine angle. بعد هيك | |
| 155 | |
| 00:13:33,110 --> 00:13:39,630 | |
| بيفوت لل internal auditory | |
| 156 | |
| 00:13:39,630 --> 00:13:45,210 | |
| meatus. لل facial canal. facial ايه؟ canal أو | |
| 157 | |
| 00:13:45,210 --> 00:13:46,630 | |
| fallopian canal. | |
| 158 | |
| 00:13:49,240 --> 00:13:53,900 | |
| أثناء مروره في الـ facial canal إله جانجليون اسم | |
| 159 | |
| 00:13:53,900 --> 00:13:58,820 | |
| هذا الجانجليون geniculate ganglion. هذا الجانجليون | |
| 160 | |
| 00:13:58,820 --> 00:14:03,760 | |
| الـ geniculate ganglion إله three branches, greater | |
| 161 | |
| 00:14:03,760 --> 00:14:08,140 | |
| superficial petrosal nerve, nerve to stapedius | |
| 162 | |
| 00:14:08,140 --> 00:14:12,760 | |
| muscle, و chorda tympani nerve. هذول التلاثة راح نتكلم | |
| 163 | |
| 00:14:12,760 --> 00:14:19,420 | |
| عنهم و finally بيخرج من وين؟ بيخرج بيغادر عن طريق | |
| 164 | |
| 00:14:19,420 --> 00:14:24,160 | |
| stylomastoid foramen. بيخرج من وين؟ من stylomastoid | |
| 165 | |
| 00:14:24,160 --> 00:14:28,660 | |
| foramen. يقول هذا ال course بتاع اللي هو ال facial | |
| 166 | |
| 00:14:28,660 --> 00:14:31,380 | |
| nerve intracranial course. | |
| 167 | |
| 00:14:37,190 --> 00:14:41,890 | |
| نتكلم على extra cranial course of the facial nerve. | |
| 168 | |
| 00:14:41,890 --> 00:14:47,910 | |
| It leaves the skull through the stylomastoid | |
| 169 | |
| 00:14:47,910 --> 00:14:51,630 | |
| foramen. يعني هو بيغادر ال facial canal الموجودة في | |
| 170 | |
| 00:14:51,630 --> 00:14:54,590 | |
| ال skull عن طريق ال stylomastoid foramen. | |
| 171 | |
| 00:14:54,590 --> 00:15:01,350 | |
| Immediately after exit of the skull, it gives two | |
| 172 | |
| 00:15:01,350 --> 00:15:03,630 | |
| branches. بعد ما يخرج من ال skull بيعطينا | |
| 173 | |
| 00:15:03,630 --> 00:15:09,810 | |
| immediately two branches. بعد ذلك يدخل في الـ | |
| 174 | |
| 00:15:09,810 --> 00:15:16,270 | |
| posterior medial surface | |
| 175 | |
| 00:15:16,270 --> 00:15:20,150 | |
| of parotid gland. بيكون superficial لـ external | |
| 176 | |
| 00:15:20,150 --> 00:15:26,750 | |
| carotid artery, و it ends inside of the substance | |
| 177 | |
| 00:15:26,750 --> 00:15:32,710 | |
| part of the gland by dividing into five terminal | |
| 178 | |
| 00:15:32,710 --> 00:15:36,610 | |
| branches. و في الأخير بيعطينا five branches. يعني | |
| 179 | |
| 00:15:36,610 --> 00:15:41,150 | |
| طلع ال facial nerve له كام branch؟ عشرة، له عشرة، | |
| 180 | |
| 00:15:41,150 --> 00:15:46,000 | |
| ثلاثة موجودين في ال facial canal, اثنين immediately | |
| 181 | |
| 00:15:46,000 --> 00:15:48,660 | |
| after exit و اثنين بعد ما يخرج من | |
| 182 | |
| 00:15:48,660 --> 00:15:52,360 | |
| الـ stylomastoid foramen و خمسة terminal branches. | |
| 183 | |
| 00:15:52,360 --> 00:15:59,820 | |
| صاروا كام؟ صاروا عندي عشرة branches. لمن لاله facial | |
| 184 | |
| 00:15:5 | |
| 201 | |
| 00:17:27,980 --> 00:17:34,860 | |
| small branch to stapedius muscle ايه بجنه؟ هذا | |
| 202 | |
| 00:17:34,860 --> 00:17:40,680 | |
| small branch للاستابيدياس muscle يعتبر motor جي اس بي | |
| 203 | |
| 00:17:40,680 --> 00:17:46,360 | |
| إن بارا sympathetic الكوردة تنبع يعتبر بارا | |
| 204 | |
| 00:17:46,360 --> 00:17:52,370 | |
| sympathetic و sensory و هي و sensory Posterior | |
| 205 | |
| 00:17:52,370 --> 00:17:56,110 | |
| Auricular Nerve يعتبر motor مع Sensory مع بعض | |
| 206 | |
| 00:17:56,110 --> 00:17:59,950 | |
| Nerve of Posterior Belly of the Digastric Muscle | |
| 207 | |
| 00:17:59,950 --> 00:18:05,710 | |
| motor و Terminal five branches temporal nerve motor | |
| 208 | |

| 210 | |
| 00:18:25,670 --> 00:18:30,930 | |
| اثنين immediately after exit وخمسة terminal الثلاثة | |
| 211 | |
| 00:18:30,930 --> 00:18:34,510 | |
| اللي بيكونوا في ال canal داخل ال canal واحد GSBN | |
| 212 | |
| 00:18:34,510 --> 00:18:37,850 | |
| اللي هو greater superficial petrosal nerve ثمين | |
| 213 | |
| 00:18:37,850 --> 00:18:42,670 | |
| small branch to stapedius muscle ثلاثة corda | |
| 214 | |
| 00:18:42,670 --> 00:18:48,470 | |
| tympani nerve ال two nerves immediately after exit | |
| 215 | |
| 00:18:48,470 --> 00:18:51,930 | |
| from stylomastoid foramen اللي هو posterior | |
| 216 | |
| 00:18:51,930 --> 00:18:56,010 | |
| auricular nerveو nerve to posterior belly of | |
| 217 | |
| 00:18:56,010 --> 00:19:00,230 | |
| digastric muscle and stylohyoid muscle وخمسة | |
| 218 | |
| 00:19:00,230 --> 00:19:03,610 | |
| terminal branches temporal nerve زي Zygomatic nerve, | |
| 219 | |
| 00:19:04,030 --> 00:19:07,310 | |
| buccal nerve, marginal mandibular nerve and | |
| 220 | |
| 00:19:07,310 --> 00:19:13,890 | |
| cervical nerve الآن في ال slide هذا راح اتكلم على | |
| 221 | |
| 00:19:14,740 --> 00:19:19,660 | |
| الـ branches الثلاثة الموجودين في الـ canal GSPN | |
| 222 | |
| 00:19:19,660 --> 00:19:24,460 | |
| أو Greater Superficial Petrosal Nerve it is a | |
| 223 | |
| 00:19:24,460 --> 00:19:29,700 | |
| parasympathetic nerve carry parasympathetic fibers | |
| 224 | |
| 00:19:29,700 --> 00:19:34,560 | |
| to the lacrimal gland, nasal gland, nasopharyngeal | |
| 225 | |
| 00:19:34,560 --> 00:19:40,560 | |
| gland, palatine gland كلها منهثمين small branch to | |
| 226 | |
| 00:19:40,560 --> 00:19:44,260 | |
| the stapedius muscle in the middle ear اللي هو | |
| 227 | |
| 00:19:44,260 --> 00:19:49,260 | |
| يعتبر motor nerve reduce excessive vibration and | |
| 228 | |
| 00:19:49,260 --> 00:19:53,280 | |
| sound transmission to inner ear بيكون جيرانكوا | |
| 229 | |
| 00:19:53,280 --> 00:19:57,660 | |
| عندهم حفلة طول الليل و هم أغاني مش عارفين أين | |
| 230 | |
| 00:19:57,660 --> 00:20:02,280 | |
| جايبينها و الإنسان بيرهق من سمح الأغاني اللي مش | |
| 231 | |
| 00:20:02,280 --> 00:20:07,890 | |
| حلوة و ماعليهاش أي معنى و حرامماذا تفعل هذه | |
| 232 | |
| 00:20:07,890 --> 00:20:11,330 | |
| العضلة؟ هذه العضلة تحدث لها contraction لـ | |
| 233 | |
| 00:20:11,330 --> 00:20:14,830 | |
| Stapedius muscle لماذا تعمل contraction؟ عشان نقلل | |
| 234 | |
| 00:20:14,830 --> 00:20:19,770 | |
| توصيل الصوت من الأذن الوسطى للأذن الداخلية إذا كان | |
| 235 | |
| 00:20:19,770 --> 00:20:22,570 | |
| حفلة عن جيرانكوا طول الوقت تكون Stapedius muscle في | |
| 236 | |
| 00:20:22,570 --> 00:20:26,750 | |
| وضع contraction ما هو وظيفتها؟ reduction excessive | |
| 237 | |
| 00:20:26,750 --> 00:20:32,670 | |
| vibration and sound transmission from middle ear to | |
| 238 | |
| 00:20:32,670 --> 00:20:35,790 | |
| inner ear، يبقى بالعربي هذه العضلة عندما تحصل على | |
| 239 | |
| 00:20:35,790 --> 00:20:39,650 | |
| contraction تعمل تخفيض للصوت العالي، توصيل الصوت | |
| 240 | |
| 00:20:39,650 --> 00:20:43,650 | |
| العالي من الأذن الوسطى لين؟ للأذن الداخلية، لكن | |
| 241 | |
| 00:20:43,650 --> 00:20:47,770 | |
| لو ما كانت شغالة هذه العضلة، بيحدث عندنا شيء اسمه | |
| 242 | |
| 00:20:47,770 --> 00:20:51,250 | |
| hyperacusia، hyper ايه؟ Acusia | |
| 243 | |
| 00:20:53,830 --> 00:20:56,630 | |
| يعني لو أنا بقرا محاضرة إلكوا اللي عنده | |
| 244 | |
| 00:20:56,630 --> 00:20:59,350 | |
| hyperacusia بقدرش تحمل محاضرة الصوت بيكون | |
| 245 | |
| 00:20:59,350 --> 00:21:05,960 | |
| بالنسبة له عالي كثير و مزعج كثير ثلاثة corda تنبع | |
| 246 | |
| 00:21:05,960 --> 00:21:09,740 | |
| nerve هذا يعتبر بارا سيمباتاتيك و special sensory | |
| 247 | |
| 00:21:09,740 --> 00:21:15,660 | |
| nerve يعطي بارا سيمباتاتيك fibers ل submandibular و | |
| 248 | |
| 00:21:15,660 --> 00:21:20,320 | |
| sublingual salivary gland بيغذي ال submandibular و | |
| 249 | |
| 00:21:20,320 --> 00:21:23,260 | |
| sublingual salivary gland العلاقة في ال production | |
| 250 | |
| 00:21:23,260 --> 00:21:27,780 | |
| of saliva اثنين sub lingual taste ال sensation بيغذي | |
| 251 | |
| 00:21:27,780 --> 00:21:35,130 | |
| التذوق from anterior two third of the tongue هي عندي | |
| 252 | |
| 00:21:35,130 --> 00:21:39,170 | |
| اللي هو greater superficial petrosal nerve هاي | |
| 253 | |
| 00:21:39,170 --> 00:21:44,790 | |
| nerve to stapedius muscle وهي | |
| 254 | |
| 00:21:44,790 --> 00:21:48,890 | |
| عندي اللي هو corda tympani nerve وخرج من وين؟ من | |
| 255 | |
| 00:21:48,890 --> 00:21:53,870 | |
| stylomastoid foramen من stylomastoid foramen خرج | |
| 256 | |
| 00:21:53,870 --> 00:21:57,730 | |
| من ال facial nerve هيك بيكون أنا شرحتلكوا أول | |
| 257 | |
| 00:21:57,730 --> 00:22:06,170 | |
| ثلاثة عندي بعد هيك اللي هو facial nerve بيخرج من | |
| 258 | |
| 00:22:06,170 --> 00:22:10,590 | |
| stylomastoid foramen وبيعطينا two branches | |
| 259 | |
| 00:22:10,590 --> 00:22:15,250 | |
| posterior auricular nerve and nerve to posterior | |
| 260 | |
| 00:22:15,250 --> 00:22:20,370 | |
| belly of the digastric muscle and stylohyoid muscle | |
| 261 | |
| 00:22:20,370 --> 00:22:26,230 | |
| هاي | |
| 262 | |
| 00:22:26,230 --> 00:22:33,850 | |
| عندي اللي هو ال facial nerve بيخرج من الـ stylo | |
| 263 | |
| 00:22:33,850 --> 00:22:43,130 | |
| mastoid foramen الآن | |
| 264 | |
| 00:22:43,130 --> 00:22:48,490 | |
| أتكلم على branches of the facial nerve immediately | |
| 265 | |
| 00:22:48,490 --> 00:22:52,930 | |
| after exit from the skull بعد ما يخرج من ال skull | |
| 266 | |
| 00:22:52,930 --> 00:22:55,990 | |
| من ال stylomastoid foramen immediately it gives | |
| 267 | |
| 00:22:55,990 --> 00:23:01,000 | |
| two branches أول واحد posterior auricular nerve | |
| 268 | |
| 00:23:01,000 --> 00:23:05,920 | |
| posterior auricular nerve supply of occipital belly | |
| 269 | |
| 00:23:05,920 --> 00:23:11,260 | |
| of occipitofrontalis muscle supply also superior | |
| 270 | |
| 00:23:11,260 --> 00:23:16,000 | |
| and posterior auricularis muscle بيغذي ال | |
| 271 | |
| 00:23:16,000 --> 00:23:18,020 | |
| superior و ال posterior auricularis muscle | |
| 272 | |
| 00:23:20,910 --> 00:23:25,630 | |
| أوريكولار muscle لها جزءين جزء posterior و جزء | |
| 273 | |
| 00:23:25,630 --> 00:23:30,230 | |
| anterior هو أدق بيغذي بيغذي posterior part بيغذي | |
| 274 | |
| 00:23:30,230 --> 00:23:33,830 | |
| posterior part لأن ال temporal nerve راح يغذي main | |
| 275 | |
| 00:23:33,830 --> 00:23:38,050 | |
| anterior part يبقى ال posterior auricular nerve | |
| 276 | |
| 00:23:38,050 --> 00:23:41,930 | |
| راح يغذي أدق ال posterior part of superior | |
| 277 | |
| 00:23:41,930 --> 00:23:46,770 | |
| auricular muscle Okay و ايه العلاقة بموضوع ال | |
| 278 | |
| 00:23:46,770 --> 00:23:51,650 | |
| sensation from the posterior part of the auricle | |
| 279 | |
| 00:23:51,650 --> 00:23:56,330 | |
| and tympanic membrane العصب الثاني من اسمه واضح | |
| 280 | |
| 00:23:56,330 --> 00:23:59,710 | |
| اسمه nerve to posterior belly of the digastric | |
| 281 | |
| 00:23:59,710 --> 00:24:02,630 | |
| muscle and the stylohyoid muscle في غذي ال | |
| 282 | |
| 00:24:02,630 --> 00:24:05,530 | |
| posterior belly of the digastric muscle and the | |
| 283 | |
| 00:24:05,530 --> 00:24:10,590 | |
| stylohyoid muscle هي عندي اللي هو posterior | |
| 284 | |
| 00:24:10,590 --> 00:24:17,240 | |
| auricular nerve Posterior Auricular nerve خرج | |
| 285 | |
| 00:24:17,240 --> 00:24:22,380 | |
| immediately تونيرف posterior auricular nerve و nerve | |
| 286 | |
| 00:24:22,380 --> 00:24:25,860 | |
| to posterior belly digastric muscle و stylohyoid نتكلم | |
| 287 | |
| 00:24:25,860 --> 00:24:29,340 | |
| عن posterior auricular بيغذي occipital belly او | |
| 288 | |
| 00:24:29,340 --> 00:24:35,560 | |
| occipitofrontalis muscle بيغذي posterior auricular | |
| 289 | |
| 00:24:35,560 --> 00:24:41,050 | |
| muscle و بيغذي ال posterior part of superior | |
| 290 | |
| 00:24:41,050 --> 00:24:45,070 | |
| auricular muscle هذا هو posterior auricular nerve | |
| 291 | |
| 00:24:45,070 --> 00:24:49,030 | |
| و بيعطينا أو receive sensation from the posterior | |
| 292 | |
| 00:24:49,030 --> 00:24:53,810 | |
| auricle and posterior tympanic membrane هذا أول | |
| 293 | |
| 00:24:53,810 --> 00:25:02,040 | |
| branch after exit هاي عندي واضح Occipital belly of | |
| 294 | |
| 00:25:02,040 --> 00:25:05,820 | |
| occipitofrontalis muscle هي posterior auricular | |
| 295 | |
| 00:25:05,820 --> 00:25:11,420 | |
| muscle وهو بيغذي posterior part of superior | |
| 296 | |
| 00:25:11,420 --> 00:25:16,680 | |
| auricular بعد هيك عندي five .. في عندي بعدها | |
| 297 | |
| 00:25:16,680 --> 00:25:21,320 | |
| بييجي five terminal branches في عندي five | |
| 298 | |
| 00:25:21,320 --> 00:25:25,580 | |
| terminal branches خمسة اللي هو temporal nerve | |
| 299 | |
| 00:25:26,610 --> 00:25:30,830 | |
| zygomatic nerve, buccal nerve, marginal mandibular | |
| 300 | |
| 00:25:30,830 --> 00:25:34,210 | |
| nerve and cervical nerve هذول terminal branches | |
| 301 | |
| 00:25:34,210 --> 00:25:39,910 | |
| temporal nerve نتكلم واحد واحد temporal nerve | |
| 302 | |
| 00:25:39,910 --> 00:25:45,530 | |
| supply the frontal belly of frontalis muscle | |
| 303 | |
| 00:25:45,530 --> 00:25:52,640 | |
| upper part of orbicularis oculi muscle superior and | |
| 304 | |
| 00:25:52,640 --> 00:25:56,100 | |
| anterior auricularis muscle نشوفهم مع بعض ايش | |
| 305 | |
| 00:25:56,100 --> 00:26:01,460 | |
| بيغذي ال temporal nerve بيغذي اللي هو frontal | |
| 306 | |
| 00:26:01,460 --> 00:26:08,130 | |
| belly of و frontalis muscle بيغذي من؟ anterior | |
| 307 | |
| 00:26:08,130 --> 00:26:13,790 | |
| auricularis muscle وبيغذي ال anterior part of | |
| 308 | |
| 00:26:13,790 --> 00:26:18,350 | |
| superior auricular muscle وبيغذي ال upper part of | |
| 309 | |
| 00:26:18,350 --> 00:26:22,650 | |
| orbicularis oculi muscle تمام؟ هذا من بيغذيهم؟ | |
| 310 | |
| 00:26:22,650 --> 00:26:32,490 | |
| اللي هو temporal nerve نرجع لل slide zygomatic | |
| 311 | |
| 00:26:32,490 --> 00:26:37,830 | |
| nerve ال zygomatic nerve بنقسم لقسمين upper | |
| 312 | |
| 00:26:37,830 --> 00:26:43,910 | |
| zygomatic branch and lower zygomatic branch ال | |
| 313 | |
| 00:26:43,910 --> 00:26:50,510 | |
| upper zygomatic branch بيغذي superior | |
| 314 | |
| 00:26:50,510 --> 00:26:53,110 | |
| or inferior part of the orbicularis oculi muscle | |
| 315 | |
| 00:26:53,110 --> 00:26:58,110 | |
| اللي بتغمض العين بيغذي ال lower zygomatic muscle | |
| 316 | |
| 00:26:58,110 --> 00:27:03,210 | |
| between the eye and mouth including nasal muscle | |
| 317 | |
| 00:27:03,210 --> 00:27:07,050 | |
| يبقى في الحالة هذه ال upper zygomatic nerve بيغذي | |
| 318 | |
| 00:27:07,050 --> 00:27:11,070 | |
| لنا ال orbicularis oculi muscle هذه ال upper part | |
| 319 | |
| 00:27:11,070 --> 00:27:16,530 | |
| و ال lower part هذه كلها بتاخد من أين؟ من upper | |
| 320 | |
| 00:27:16,530 --> 00:27:19,630 | |
| zygomatic و ال lower zygomatic بيغذي ال muscles | |
| 321 | |
| 00:27:19,630 --> 00:27:27,510 | |
| between the mouth and eye including nasal muscles | |
| 322 | |
| 00:27:27,510 --> 00:27:33,390 | |
| هذول بياخدوا من وين؟ من ال lower zygomatic branch | |
| 323 | |
| 00:27:33,390 --> 00:27:36,450 | |
| في | |
| 324 | |
| 00:27:36,450 --> 00:27:43,990 | |
| بعدها buccal nerve بيغذي buccinator muscle and | |
| 325 | |
| 00:27:43,990 --> 00:27:47,090 | |
| orbicularis oris muscle orbicularis oris muscle | |
| 326 | |
| 00:27:47,090 --> 00:27:52,510 | |
| اني أنا لما بصفّر بحركها لما بسكر فمي بحركها هذه هي | |
| 327 | |
| 00:27:53,850 --> 00:27:59,450 | |
| Buccinator muscle تاخد من ال buccal و orbicularis | |
| 328 | |
| 00:27:59,450 --> 00:28:05,110 | |
| oris muscle تاخد من ال buccal nerve | |
| 329 | |
| 00:28:08,670 --> 00:28:14,150 | |
| الفرع اللي بعده اللي هو marginal mandibular nerve | |
| 330 | |
| 00:28:14,150 --> 00:28:19,050 | |
| supply the muscles in the region of the mandible | |
| 331 | |
| 00:28:19,050 --> 00:28:22,970 | |
| وفي cervical muscle أو cervical nerve بيغذي | |
| 332 | |
| 00:28:22,970 --> 00:28:29,860 | |
| platysma muscle يبقى هاد ال muscles في ال angle of | |
| 333 | |
| 00:28:29,860 --> 00:28:33,720 | |
| the mandible تمام أو angle of the mouth تاخد من ال | |
| 334 | |
| 00:28:33,720 --> 00:28:36,840 | |
| marginal mandibular nerve وهاد ال platysma muscle | |
| 335 | |
| 00:28:36,840 --> 00:28:40,840 | |
| راح تاخد من وين ال platysma muscle من اللي هو ال | |
| 336 | |
| 00:28:40,840 --> 00:28:45,800 | |
| cervical nerve of facial هكذا بيكون أنا شرحتلكم | |
| 337 | |
| 00:28:45,800 --> 00:28:51,220 | |
| ten branches of facial nerve شرحت العشر أعصاب يبقى | |
| 338 | |
| 00:28:51,220 --> 00:28:55,430 | |
| هاي عندي zygomatic nerve تمام؟ بيغذي مين؟ | |
| 339 | |
| 00:28:55,430 --> 00:28:59,510 | |
| ال orbicularis و ال muscles | |
| 340 | |
| 00:29:00,680 --> 00:29:05,080 | |
| between the eye and mouth including nasal muscle | |
| 341 | |
| 00:29:05,080 --> 00:29:08,880 | |
| أنا هأعلملكوا عليهم ال buccal nerve بيغذي orbicularis | |
| 342 | |
| 00:29:08,880 --> 00:29:12,480 | |
| oris muscle و buccinator muscle ال marginal | |
| 343 | |
| 00:29:12,480 --> 00:29:16,480 | |
| mandibular nerve بيغذي ال muscles around the | |
| 344 | |
| 00:29:16,480 --> 00:29:20,800 | |
| mouth angle و ال cervical nerve بيغذي platysma | |
| 345 | |
| 00:29:20,800 --> 00:29:25,240 | |
| muscle و هذا ال marginal واضح بيغذي ال muscles في | |
| 346 | |
| 00:29:25,240 --> 00:29:30,650 | |
| ال angle of the mouth ننتقل لموضوع راح أشرحه | |
| 347 | |
| 00:29:30,650 --> 00:29:34,710 | |
| بالتفصيل في سنة رابعة إن شاء الله إذا ظللنا طيبين هي عندي ال | |
| 348 | |
| 00:29:34,710 --> 00:29:41,970 | |
| motor nucleus motor nucleus of the facial nerve | |
| 349 | |
| 00:29:41,970 --> 00:29:50,950 | |
| تنقسم لقسمين تنقسم لقسمين قولنا جزء يعتبر ventral | |
| 350 | |
| 00:29:50,950 --> 00:29:58,190 | |
| وجزء يعتبر dorsal ال ventral | |
| 351 | |
| 00:30:01,490 --> 00:30:09,050 | |
| supply the lower quadrant of the face و الدورسل | |
| 352 | |
| 00:30:09,050 --> 00:30:16,450 | |
| supply the upper quadrant of the face الدورسل تأخذ | |
| 353 | |
| 00:30:16,450 --> 00:30:21,490 | |
| إشارة من ال ipsilateral cerebral hemisphere و من | |
| 354 | |
| 00:30:21,490 --> 00:30:26,470 | |
| ال contralateral cerebral hemisphere يعني حكمة ربنا | |
| 355 | |
| 00:30:26,470 --> 00:30:29,730 | |
| واسعة بالبعد أعطى العضلات اللي بتغمض العين | |
| 356 | |
| 00:30:29,730 --> 00:30:34,930 | |
| innervation from both cerebral hemispheres يعني ال | |
| 357 | |
| 00:30:34,930 --> 00:30:39,130 | |
| dorsal part أو ال dorsal nucleus of facial بتاخد | |
| 358 | |
| 00:30:39,130 --> 00:30:42,570 | |
| من كم cerebral hemisphere؟ من two cerebral | |
| 359 | |
| 00:30:42,570 --> 00:30:47,310 | |
| hemispheres لكن ال ventral nucleus المسئول عن ال | |
| 360 | |
| 00:30:47,310 --> 00:30:51,540 | |
| lower quadrant of the face فقط بتاخد من ال opposite | |
| 361 | |
| 00:30:51,540 --> 00:30:55,680 | |
| side، يعني في الحالة هذه، لو إنسان صار معاه جلطة | |
| 362 | |
| 00:30:55,680 --> 00:30:58,940 | |
| دماغية، جلطة دماغية في ال right cerebral | |
| 363 | |
| 00:30:58,940 --> 00:31:03,340 | |
| hemisphere، في ال right cerebral hemisphere، ايش | |
| 364 | |
| 00:31:03,340 --> 00:31:09,340 | |
| بيحدث عنده؟ مين راح يتأثر فقط؟ الدرس اللي بتتأثر؟ ما | |
| 365 | |
| 00:31:09,340 --> 00:31:13,420 | |
| بتتأثرش لأن عندها ipsilateral innervation طيب و ال | |
| 366 | |
| 00:31:13,420 --> 00:31:17,580 | |
| ventral ال ventral راح تتأثر في الحالة هذه ال | |
| 367 | |
| 00:31:17,580 --> 00:31:23,260 | |
| ventral راح تتأثر راح ينشل نص وجهه السفلي الموضوع | |
| 368 | |
| 00:31:23,260 --> 00:31:28,240 | |
| هذا ما راح أطول الآن فيه راح أشرحه بالتفصيل في سنة | |
| 369 | |
| 00:31:28,240 --> 00:31:32,520 | |
| رابعة في الأمراض بتاعة الأعصاب إن شاء الله في | |
| 370 | |
| 00:31:32,520 --> 00:31:39,070 | |
| cranial nerve disease هنا نشوف مرضى عندهم facial | |
| 371 | |
| 00:31:39,070 --> 00:31:46,830 | |
| palsy مرضى دول عندهم facial palsy لاحظوا لي المريض | |
| 372 | |
| 00:31:46,830 --> 00:31:55,030 | |
| عنده hand shell في نص وجهه على الجهة اليسرى بيغمض | |
| 373 | |
| 00:31:55,030 --> 00:31:58,470 | |
| عينه هنا مش قادر يغمض في drop في ال mouth angle | |
| 374 | |
| 00:31:58,470 --> 00:32:03,770 | |
| عينه فاتحة loss nasolabial fold مش موجودة يبقى إن | |
| 375 | |
| 00:32:03,770 --> 00:32:07,710 | |
| المريض هذا عنده شلل في العصب السابع ال GHA اليسرى | |
| 376 | |
| 00:32:07,710 --> 00:32:11,110 | |
| هذا كله بالتفصيل اللي راح أشرحه في سنة رابعة في | |
| 377 | |
| 00:32:11,110 --> 00:32:16,410 | |
| مرض اسمه Bell's palsy التهاب في أو شلل العصب | |
| 378 | |
| 00:32:16,410 --> 00:32:20,430 | |
| السابع ونتكلم على ال upper motor neuron and lower | |
| 379 | |
| 00:32:20,430 --> 00:32:23,730 | |
| motor neuron ايش أنواعهم كل هذا إن شاء الله راح | |
| 380 | |
| 00:32:23,730 --> 00:32:27,630 | |
| نتكلم عنه لاحظوا هنا المريض هذا عنده شلل في عضلات | |
| 381 | |
| 00:32:27,630 --> 00:32:30,990 | |
| الوجه على الجهة اليسرى في Bell's palsy على ال left | |
| 382 | |
| 00:32:30,990 --> 00:32:35,550 | |
| side مش قادر يغمض عينه drop mouth angle inability | |
| 383 | |
| 00:32:35,550 --> 00:32:40,030 | |
| to close the eye كل التجاعيد هذا ال nasolabial | |
| 384 | |
| 00:32:40,030 --> 00:32:44,110 | |
| fold واضحة حلوة هنا lost مش موجودة المريض عنده شلل | |
| 385 | |
| 00:32:44,110 --> 00:32:47,050 | |
| في العصب السابع على الجهة اليسرى | |
| 386 | |
| 00:32:57,770 --> 00:33:01,770 | |
| نفس الشيء هذا الشاب بس هنا على اليمين شايفين لاحظوا في | |
| 387 | |
| 00:33: | |
| 401 | |
| 00:33:55,650 --> 00:33:59,550 | |
| نتكلم عن Glossopharyngeal nerve, Vegas nerve و | |
| 402 | |
| 00:33:59,550 --> 00:34:03,070 | |
| accessory and hypoglossal nerve موضوع | |
| 403 | |
| 00:34:03,070 --> 00:34:06,430 | |
| vestibulocochlear nerve بتكلم عنه في محاضرة إن شاء | |
| 404 | |
| 00:34:06,430 --> 00:34:10,770 | |
| الله الـ special sensation اللي هو sense of hearing | |
| 405 | |
| 00:34:10,770 --> 00:34:15,330 | |
| هيك بكون أنهيت الجزء الأول من محاضرة تبع الأسبوع | |
