| 00:00:04,990 --> 00:00:08,770 | |
| بسم الله الرحمن الرحيم السلام عليكم ورحمة الله | |
| 2 | |
| 00:00:08,770 --> 00:00:16,400 | |
| وبركاتهاليوم راح نكمل محاضرات مساق تشريح الأعصاب و | |
| 3 | |
| 00:00:16,400 --> 00:00:20,480 | |
| فسيولوجية الأعصاب وصلنا معاكم إلى المحاضرة رقم 5 | |
| 4 | |
| 00:00:20,480 --> 00:00:26,440 | |
| اللي كانت على meninges and ventricular system | |
| 5 | |
| 00:00:26,440 --> 00:00:31,840 | |
| محاضرة الأسبوع السادس راح تكون على blood supply of | |
| 6 | |
| 00:00:31,840 --> 00:00:38,910 | |
| the brain and ural venousأو Dural Venous نبدأ | |
| 7 | |
| 00:00:38,910 --> 00:00:45,090 | |
| بداية المحاضرة على ال cerebral blood flow ايش هو | |
| 8 | |
| 00:00:45,090 --> 00:00:51,190 | |
| ال cerebral blood flow؟ هو عبارة عن blood supply | |
| 9 | |
| 00:00:51,190 --> 00:00:59,250 | |
| to the brain in a given time في الطبيعي ال brain | |
| 10 | |
| 00:00:59,250 --> 00:01:08,180 | |
| بياخد 20% من ال total cardiac outputيعني حوالي 750 | |
| 11 | |
| 00:01:08,180 --> 00:01:12,500 | |
| ملي لتر في دقيقة الواحد الواحدة اللي بيصل ال blood | |
| 12 | |
| 00:01:12,500 --> 00:01:19,360 | |
| لل brain لو أخدنا دراسة regional cerebral blood | |
| 13 | |
| 00:01:19,360 --> 00:01:23,520 | |
| flowدرسنا كل 100 جرام brain tissue كم بيصل لها | |
| 14 | |
| 00:01:23,520 --> 00:01:29,120 | |
| blood في الدقيقة الواحدة طبيعي يصل 50 ل 54 مليليتر | |
| 15 | |
| 00:01:29,120 --> 00:01:32,800 | |
| في الدقيقة الواحدة هذا طبيعي طيب ماذا بيحدث | |
| 16 | |
| 00:01:32,800 --> 00:01:36,960 | |
| ischemia ischemia يعني ان الخلايا بتفقد وظيفتها | |
| 17 | |
| 00:01:36,960 --> 00:01:42,160 | |
| بدون ما يكون عندهم death لسه ما ماتت الخلية فقدت | |
| 18 | |
| 00:01:42,160 --> 00:01:46,020 | |
| الوظيفة بسبب نقص في التروية يقول ischemia هي عبارة | |
| 19 | |
| 00:01:46,020 --> 00:01:53,430 | |
| عن نقص تروية ماذا بتحدث؟if blood flow to the brain | |
| 20 | |
| 00:01:53,430 --> 00:02:01,030 | |
| below 18-20 milliliter per 100 gram per minute طيب | |
| 21 | |
| 00:02:01,030 --> 00:02:05,950 | |
| تشدث متى الخلية بتفقد الوظيفة و بتموت كمان بيحدث | |
| 22 | |
| 00:02:05,950 --> 00:02:14,330 | |
| لها death في حالنزل الـ cerebral blood flow أقل | |
| 23 | |
| 00:02:14,330 --> 00:02:21,630 | |
| من 8 ل 10 ملي لتر لكل 100 جرام برن تشوف في الدقيقة | |
| 24 | |
| 00:02:21,630 --> 00:02:28,950 | |
| الواحدة هيفجان اتفقنا انه طبيعي يصل لبرن 750 ملي | |
| 25 | |
| 00:02:28,950 --> 00:02:34,090 | |
| لتر لكل برن في الدقيقة الواحدة يعني نتكلم عن 15 ل | |
| 26 | |
| 00:02:34,090 --> 00:02:37,350 | |
| 20% من ال total cardiac output | |
| 27 | |
| 00:02:42,050 --> 00:02:47,330 | |
| الخلية بتفقد الوظيفة بتاعتها في حال نزل ال blood | |
| 28 | |
| 00:02:47,330 --> 00:02:56,750 | |
| flow لكام؟ ل 18، 20 مليلتر ل 100 gram brain tissue | |
| 29 | |
| 00:02:56,750 --> 00:03:01,330 | |
| في الدقيقة الواحدة طب death tissue او ال tissue | |
| 30 | |
| 00:03:01,330 --> 00:03:05,070 | |
| death متى بيحدث ال tissue death؟في حال نزل الـ | |
| 31 | |
| 00:03:05,070 --> 00:03:07,230 | |
| cerebral blood flow، الـ regional cerebral blood | |
| 32 | |
| 00:03:07,230 --> 00:03:14,010 | |
| flow، below a 10 milliliter blood لكل 100 gram | |
| 33 | |
| 00:03:14,010 --> 00:03:20,110 | |
| brain tissue per minute blood | |
| 34 | |
| 00:03:20,110 --> 00:03:27,470 | |
| supply of the brainالـ brain very important organ | |
| 35 | |
| 00:03:27,470 --> 00:03:33,370 | |
| عشان هيك لاحظوا انه بيصلوا عشرين في المية من a | |
| 36 | |
| 00:03:33,370 --> 00:03:40,050 | |
| total cardiac output مهم جدا بتأثر ال brain في | |
| 37 | |
| 00:03:40,050 --> 00:03:43,070 | |
| حالات ال hypertension او في حالات ال hypertension | |
| 38 | |
| 00:03:43,070 --> 00:03:50,310 | |
| ال blood supply of the brain ال brain بيصلوا blood | |
| 39 | |
| 00:03:50,310 --> 00:03:59,060 | |
| من two systemsتو system اول system اللي هو ايه | |
| 40 | |
| 00:03:59,060 --> 00:04:03,680 | |
| carotid system carotid system ثاني system | |
| 41 | |
| 00:04:03,680 --> 00:04:11,580 | |
| vertebrobasilar system vertebrobasilar system ال | |
| 42 | |
| 00:04:11,580 --> 00:04:18,030 | |
| carotid systemبصلى ال brain عن طريق internal | |
| 43 | |
| 00:04:18,030 --> 00:04:22,570 | |
| carotid artery internal carotid artery هنا right | |
| 44 | |
| 00:04:22,570 --> 00:04:27,530 | |
| internal carotid artery and left internal carotid | |
| 45 | |
| 00:04:27,530 --> 00:04:31,960 | |
| artery طيب ال vertebral basilar systemبيصل ال | |
| 46 | |
| 00:04:31,960 --> 00:04:35,980 | |
| blood لل brain عن طريق ال two vertebral artery و | |
| 47 | |
| 00:04:35,980 --> 00:04:39,560 | |
| ال two vertebral artery بتحدوا مع بعض و بيكونولنا | |
| 48 | |
| 00:04:39,560 --> 00:04:45,500 | |
| single basilar artery لذلك سميها vertebral basilar | |
| 49 | |
| 00:04:45,500 --> 00:04:54,260 | |
| system the main blood supply to the brain بتتم عن | |
| 50 | |
| 00:04:54,260 --> 00:04:56,740 | |
| طريق ال carotid artery عن طريق ال internal carotid | |
| 51 | |
| 00:04:56,740 --> 00:05:03,670 | |
| artery internal carotid arterysupplied 80% of the | |
| 52 | |
| 00:05:03,670 --> 00:05:08,190 | |
| brain يعني 80% من الدماغ بياخد إبلاد سبلية عن طريق | |
| 53 | |
| 00:05:08,190 --> 00:05:13,730 | |
| ال internal carotid artery و 20% بياخد عن طريق | |
| 54 | |
| 00:05:13,730 --> 00:05:19,390 | |
| vertebral basilar artery نرجع | |
| 55 | |
| 00:05:19,390 --> 00:05:24,450 | |
| شوية ال general anatomy نشوف من وين ال origin بتاع | |
| 56 | |
| 00:05:24,450 --> 00:05:30,330 | |
| ال internal carotid artery أول شيءفي هنا شي اسمه | |
| 57 | |
| 00:05:30,330 --> 00:05:34,290 | |
| common carotid artery الـ carotid يعني شريان | |
| 58 | |
| 00:05:34,290 --> 00:05:39,590 | |
| السباتي شريان السباتي العام بالعربي common carotid | |
| 59 | |
| 00:05:39,590 --> 00:05:43,990 | |
| artery أو شريان السباتي الرئيسي ال common carotid | |
| 60 | |
| 00:05:43,990 --> 00:05:51,870 | |
| artery emerges from هنا الخلاف في right و في left | |
| 61 | |
| 00:05:51,870 --> 00:05:59,070 | |
| ال right common carotid arteryemerges from | |
| 62 | |
| 00:05:59,070 --> 00:06:05,270 | |
| brachiocephalic trunk from brachiocephalic trunk | |
| 63 | |
| 00:06:05,270 --> 00:06:09,650 | |
| طيب، brachiocephalic trunk بخرج من القرش و في | |
| 64 | |
| 00:06:09,650 --> 00:06:13,750 | |
| أوورته brachiocephalic | |
| 65 | |
| 00:06:13,750 --> 00:06:17,790 | |
| trunk من اسمه brachiocephalic يعني لل upper limb و | |
| 66 | |
| 00:06:17,790 --> 00:06:22,370 | |
| لل brain ال brachiocephalic trunk ال right منقسم ل | |
| 67 | |
| 00:06:22,370 --> 00:06:28,250 | |
| two arteries two main arteriesأولاً رايت سبكليفيان | |
| 68 | |
| 00:06:28,250 --> 00:06:37,570 | |
| ارتريه اللي تشتغل عقل العقل الأعلى اتنين | |
| 69 | |
| 00:06:37,570 --> 00:06:43,750 | |
| كومون كاروتد ارتريه يبقى رايت كومون كاروتد ارتريه | |
| 70 | |
| 00:06:43,750 --> 00:06:47,350 | |
| يتخلص | |
| 71 | |
| 00:06:47,350 --> 00:06:54,620 | |
| منthe brachiocephalic trunk ماحد يقول ليه من ال | |
| 72 | |
| 00:06:54,620 --> 00:06:59,400 | |
| right brachiocephalic trunk ليه؟ لأنه هو one only | |
| 73 | |
| 00:06:59,400 --> 00:07:01,960 | |
| على ال right بيكون موجود على ال brachiocephalic | |
| 74 | |
| 00:07:01,960 --> 00:07:06,060 | |
| trunk في الحالة هذه ال right common carotid artery | |
| 75 | |
| 00:07:06,060 --> 00:07:12,160 | |
| immerse from brachiocephalic trunkBreak ocephalic | |
| 76 | |
| 00:07:12,160 --> 00:07:16,660 | |
| trunk Divide into two arteries Right subclavian | |
| 77 | |
| 00:07:16,660 --> 00:07:19,620 | |
| artery and right common carotid artery | |
| 78 | |
| 00:07:27,320 --> 00:07:32,180 | |
| immediately direct from the arch of the aorta يعني | |
| 79 | |
| 00:07:32,180 --> 00:07:35,000 | |
| عال left الarch of the aorta عال left بيكون | |
| 80 | |
| 00:07:35,000 --> 00:07:40,520 | |
| immediately بخرج منه left subclavian artery and | |
| 81 | |
| 00:07:40,520 --> 00:07:44,280 | |
| left common carotid artery يبقى هنا عرفنا إيش | |
| 82 | |
| 00:07:44,280 --> 00:07:47,600 | |
| الاختلاف بين ال right و left common carotid artery | |
| 83 | |
| 00:07:47,600 --> 00:07:52,360 | |
| left common carotid artery emerges immediatelyfrom | |
| 84 | |
| 00:07:52,360 --> 00:07:56,780 | |
| the arch of the aorta but the right common carotid | |
| 85 | |
| 00:07:56,780 --> 00:08:01,220 | |
| artery emerges or arises directly from | |
| 86 | |
| 00:08:01,220 --> 00:08:04,340 | |
| brachiocephalic trunk و brachiocephalic trunk من | |
| 87 | |
| 00:08:04,340 --> 00:08:09,480 | |
| وين؟ من ال arch of the aorta خلصنا عرفنا من وين | |
| 88 | |
| 00:08:09,480 --> 00:08:11,740 | |
| أتى ال common carotid artery مابهمناش احنا ال | |
| 89 | |
| 00:08:11,740 --> 00:08:14,560 | |
| common carotid artery بهمنا ال internal carotid | |
| 90 | |
| 00:08:14,560 --> 00:08:19,580 | |
| artery طيب common carotid artery بينقسم ل two | |
| 91 | |
| 00:08:19,580 --> 00:08:25,640 | |
| branchesلـ Internal Carotid Artery و External | |
| 92 | |
| 00:08:25,640 --> 00:08:28,860 | |
| Carotid Artery، أنا الـ External Carotid Artery ما | |
| 93 | |
| 00:08:28,860 --> 00:08:32,920 | |
| بيهمني اليوم، بغد الـ Face و الـ Thyroid، ما إلي | |
| 94 | |
| 00:08:32,920 --> 00:08:35,970 | |
| علاقة في الموضوع الآن؟أنا باهيم من مين؟ ال | |
| 95 | |
| 00:08:35,970 --> 00:08:38,870 | |
| internal carotid artery طب وين بيتم ال | |
| 96 | |
| 00:08:38,870 --> 00:08:45,110 | |

| 107 | |
| 00:09:05,260 --> 00:09:09,440 | |
| vertibra يبقى common carotid artery بتميله by | |
| 108 | |
| 00:09:09,440 --> 00:09:13,220 | |
| bifurcation dividing ال common carotid artery | |
| 109 | |
| 00:09:13,220 --> 00:09:19,260 | |
| divide لمين ل two arteries internal carotid artery | |
| 110 | |
| 00:09:19,260 --> 00:09:24,300 | |
| و external carotid artery انا اللي بهمنياللي هو | |
| 111 | |
| 00:09:24,300 --> 00:09:27,820 | |
| internal | |
| 112 | |
| 00:09:27,820 --> 00:09:32,400 | |
| carotid artery ننتقل | |
| 113 | |
| 00:09:32,400 --> 00:09:39,900 | |
| لموضوع تاني هاي واضح انها في الصورة أرش أو داورتا | |
| 114 | |
| 00:09:39,900 --> 00:09:46,000 | |
| على ال right brachiocephalic trunkتنقسم لـ right | |
| 115 | |
| 00:09:46,000 --> 00:09:50,520 | |
| subclavian artery و right common carotid artery | |
| 116 | |
| 00:09:50,520 --> 00:09:55,000 | |
| نشوف الـ left هي عندي ارشف دورته Direct بخرج منه | |
| 117 | |
| 00:09:55,000 --> 00:09:59,740 | |
| left subclavian artery و left common carotid | |
| 118 | |
| 00:09:59,740 --> 00:10:12,540 | |
| artery طيب | |
| 119 | |
| 00:10:12,540 --> 00:10:17,830 | |
| لو سؤالنا سؤالجيبنا صورة زي هيك و قولنا what's the | |
| 120 | |
| 00:10:17,830 --> 00:10:21,950 | |
| difference between external carotid artery and | |
| 121 | |
| 00:10:21,950 --> 00:10:25,370 | |
| internal carotid artery هي عندي common carotid | |
| 122 | |
| 00:10:25,370 --> 00:10:28,970 | |
| artery عن ال right خرج من ال subclavian artery .. | |
| 123 | |
| 00:10:28,970 --> 00:10:31,730 | |
| آسف خرج من ال brachiocephalic trunk ال | |
| 124 | |
| 00:10:31,730 --> 00:10:35,310 | |
| brachiocephalic trunk انقسم ل right common carotid | |
| 125 | |
| 00:10:35,310 --> 00:10:39,970 | |
| artery و right subclavian artery هذا هو ايه ال | |
| 126 | |
| 00:10:39,970 --> 00:10:43,030 | |
| brachiocephalic trunkطب what's the difference | |
| 127 | |
| 00:10:43,030 --> 00:10:46,290 | |
| between right and left؟ what's the difference | |
| 128 | |
| 00:10:46,290 --> 00:10:49,930 | |
| between internal and external carotid artery؟ أنا | |
| 129 | |
| 00:10:49,930 --> 00:10:57,610 | |
| بطلع بصورة هيك و بده أعرف هاي one و هاي second | |
| 130 | |
| 00:10:57,610 --> 00:11:01,710 | |
| branch لل common carotid main ال internal و main | |
| 131 | |
| 00:11:01,710 --> 00:11:09,230 | |
| ال externalinternal carotid artery gives no branch | |
| 132 | |
| 00:11:09,230 --> 00:11:13,390 | |
| at the neck يعني ال internal carotid artery | |
| 133 | |
| 00:11:13,390 --> 00:11:18,370 | |
| بيعطيناش ولا شريان على الرقبة، مابيعطيش ولا branch | |
| 134 | |
| 00:11:19,150 --> 00:11:24,650 | |
| طيب أما ال external carotid artery it gives | |
| 135 | |
| 00:11:24,650 --> 00:11:29,030 | |
| branches at the neck يبقى الإختلاف إن ال external | |
| 136 | |
| 00:11:29,030 --> 00:11:33,790 | |
| carotid artery بيعطينا أفرع له للرقب و لل face و | |
| 137 | |
| 00:11:33,790 --> 00:11:38,830 | |
| للوجه تمام و الفكين أما ال internal carotid artery | |
| 138 | |
| 00:11:38,830 --> 00:11:45,490 | |
| وظيفة to supply the brain and eyes لذلك بيعطيش ولا | |
| 139 | |
| 00:11:45,490 --> 00:11:47,790 | |
| فرع له على الرقب | |
| 140 | |
| 00:11:52,180 --> 00:11:58,280 | |
| نوصل لـ Internal Carotid Artery اللي هو راح يكون | |
| 141 | |
| 00:11:58,280 --> 00:12:02,820 | |
| موضوع الجزء الأول من محاضرتنا ان شاء الله Internal | |
| 142 | |
| 00:12:02,820 --> 00:12:10,540 | |
| Carotid Artery arises in the neck of terminal | |
| 143 | |
| 00:12:10,540 --> 00:12:16,700 | |
| branch of common carotid arteryat bifurcation | |
| 144 | |
| 00:12:16,700 --> 00:12:19,840 | |
| واتفجنا ال bifurcation يعني إيش bifurcation مقصود | |
| 145 | |
| 00:12:19,840 --> 00:12:24,260 | |
| فيها هو انقسام ال common carotid artery إلى | |
| 146 | |
| 00:12:24,260 --> 00:12:28,900 | |
| external and internal على أي level قلنا على level | |
| 147 | |
| 00:12:28,900 --> 00:12:34,960 | |
| cervical 3 and cervical 4 vertebra أو على level | |
| 148 | |
| 00:12:34,960 --> 00:12:40,640 | |
| upper thyroid gland cartilageOkay what's the | |
| 149 | |
| 00:12:40,640 --> 00:12:45,940 | |
| function of internal carotid artery؟ Internal | |
| 150 | |
| 00:12:45,940 --> 00:12:51,780 | |
| carotid artery supplies structures of orbit يعني | |
| 151 | |
| 00:12:51,780 --> 00:12:57,360 | |
| ال I و ال orbitand large part of the brain | |
| 152 | |
| 00:12:57,360 --> 00:13:03,960 | |
| internal carotid artery supply 80% of the brain | |
| 153 | |
| 00:13:03,960 --> 00:13:09,860 | |
| يعني 80% من ال brain blood supply بتم عن طريق مين؟ | |
| 154 | |
| 00:13:09,860 --> 00:13:16,780 | |
| عن طريق internal carotid artery واتفجنا انهit | |
| 155 | |
| 00:13:16,780 --> 00:13:22,980 | |
| gives no branches at the neck او in the neck يعني | |
| 156 | |
| 00:13:22,980 --> 00:13:27,440 | |
| ال internal carotid artery مابيعطيناش ولا branch | |
| 157 | |
| 00:13:27,440 --> 00:13:32,280 | |
| على وين على الرقبة okay تمام ال internal carotid | |
| 158 | |
| 00:13:32,280 --> 00:13:39,600 | |
| artery هو supply ال orbit و ال brain each | |
| 159 | |
| 00:13:39,600 --> 00:13:44,880 | |
| internal carotid arteryenters the skull through | |
| 160 | |
| 00:13:44,880 --> 00:13:49,800 | |
| the carotid canal او carotid foramen هو بيفوت ل ال | |
| 161 | |
| 00:13:49,800 --> 00:13:56,340 | |
| cranial cavity عن طريق قناع او فتحة اسمها carotid | |
| 162 | |
| 00:13:56,340 --> 00:14:04,620 | |
| foramen او carotid canal okay and it gives intra | |
| 163 | |
| 00:14:04,620 --> 00:14:09,380 | |
| cranial branches بيعطينا ايه intra cranial | |
| 164 | |
| 00:14:09,380 --> 00:14:15,680 | |
| branchesلو اتكلم على course of the internal | |
| 165 | |
| 00:14:15,680 --> 00:14:19,020 | |
| carotid arteryاتفاجنا انه بيبدأ ال internal | |
| 166 | |
| 00:14:19,020 --> 00:14:22,420 | |
| carotid artery من مكان ال bifurcation of common | |
| 167 | |
| 00:14:22,420 --> 00:14:28,620 | |
| carotid artery على level C3-C4 فيرتبرة ال internal | |
| 168 | |
| 00:14:28,620 --> 00:14:34,200 | |
| carotid artery بيمور واحد cervical part اللي هو | |
| 169 | |
| 00:14:34,200 --> 00:14:39,560 | |
| أجزاء أول جزء اسمه cervical part بيكون below the | |
| 170 | |
| 00:14:39,560 --> 00:14:42,680 | |
| carotid foramen وين موجود هذا الجزء؟ على ال neck | |
| 171 | |
| 00:14:42,680 --> 00:14:52,940 | |
| موجود وين؟ على ال neck اثنينانترا بترا سبارت انتوا | |
| 172 | |
| 00:14:52,940 --> 00:14:59,100 | |
| عارفين كاروتد فورامن موجود في ال بترا بون تمام of | |
| 173 | |
| 00:14:59,100 --> 00:15:02,440 | |
| temporal bone يعني ال temporal bone في جزء منها | |
| 174 | |
| 00:15:02,440 --> 00:15:06,600 | |
| اسمه بترا سبارت وفيها canal او فورامن اسمه كاروتد | |
| 175 | |
| 00:15:06,600 --> 00:15:12,060 | |
| فورامن يبقى أثناء مرور ال internal carotid artery | |
| 176 | |
| 00:15:12,900 --> 00:15:15,840 | |
| في الـ Carotid Foramen هذا الجزء اللي موجود في الـ | |
| 177 | |
| 00:15:15,840 --> 00:15:22,750 | |
| Foramen بنسميه Intrapetra Sparta ثلاثةانترا | |
| 178 | |
| 00:15:22,750 --> 00:15:26,850 | |
| كافيرنس بارد ان شاء الله في نهاية المحاضرة راح | |
| 179 | |
| 00:15:26,850 --> 00:15:30,630 | |
| ناخد ديور ال venous sinuses ومن ضمنهم كافيرنس | |
| 180 | |
| 00:15:30,630 --> 00:15:36,470 | |
| sinus ال internal carotid artery بيمر في ال media | |
| 181 | |
| 00:15:36,470 --> 00:15:41,650 | |
| wall of the cavernous sinus كافيرنس sinus هو عبارة | |
| 182 | |
| 00:15:41,650 --> 00:15:46,350 | |
| عن ديور ال venous sinusو ال internal carotid | |
| 183 | |
| 00:15:46,350 --> 00:15:49,030 | |
| artery اللي بمر فيه ايه الجزء اللي بمر في ال | |
| 184 | |
| 00:15:49,030 --> 00:15:54,210 | |
| cavernous sinus بنسميه intra cavernous part و اخر | |
| 185 | |
| 00:15:54,210 --> 00:16:00,270 | |
| جزء اسمه intracranial part above the cavernous | |
| 186 | |
| 00:16:00,270 --> 00:16:06,210 | |
| sinus في بعض المراجع بيسمو ال intra cavernous part | |
| 187 | |
| 00:16:06,210 --> 00:16:12,580 | |
| و ال intracranial part نفس الاسمهي عندى تحت بيكون | |
| 188 | |
| 00:16:12,580 --> 00:16:18,640 | |
| هذا survival part هذا الجزء بنسميه intra-pitras | |
| 189 | |
| 00:16:18,640 --> 00:16:22,280 | |
| part هذا الجزء اللى في ال cavernous sinus بنسميه | |
| 190 | |
| 00:16:22,280 --> 00:16:25,980 | |
| intra-cavernous part وجزء العلو اللى دخل في ال | |
| 191 | |
| 00:16:25,980 --> 00:16:31,020 | |
| cranial cavity نفسه بنسميه intra cranial part | |
| 192 | |
| 00:16:42,630 --> 00:16:47,310 | |
| branches of the internal carotid artery internal | |
| 193 | |
| 00:16:47,310 --> 00:16:53,410 | |
| carotid artery الو five branches يعني خمسة في عين | |
| 194 | |
| 00:16:53,410 --> 00:17:01,430 | |
| الحسود خمسة كم واحد خمسة ophthalmic branch من اسمه | |
| 195 | |
| 00:17:01,430 --> 00:17:05,650 | |
| ophthalmic branch لو ايه رايح؟ رايح لل orbit and a | |
| 196 | |
| 00:17:05,650 --> 00:17:12,620 | |
| eyePosterior communicating artery من اسمه | |
| 197 | |
| 00:17:12,620 --> 00:17:18,540 | |
| posterior متجه إلى الخلف communicating بهم الحلقة | |
| 198 | |
| 00:17:18,540 --> 00:17:24,030 | |
| وصل communication راح نتكلم عنه تلاثةAnterior | |
| 199 | |
| 00:17:24,030 --> 00:17:28,910 | |
| Coroidal Artery من اسمه بيكون شريان أمامي Coroidal | |
| 200 | |
| 00:17:28,910 --> 00:17:32,730 | |
| يعني supply Coroidal Plexus رح نتكلم عنه بالتفصيل | |
| 201 | |
| 00:17:32,730 --> 00:17:38,610 | |
| و ا two terminal branches و أكبر اتنين Anterior | |
| 202 | |
| 00:17:38,610 --> 00:17:42,770 | |
| Cerebral Artery and Middle Cerebral Artery لكن لو | |
| 203 | |
| 00:17:42,770 --> 00:17:48,890 | |
| سألنا سؤال مين هو largest branch of an internal | |
| 204 | |
| 00:17:48,890 --> 00:17:53,680 | |
| carotid artery رح يكون middle cerebral arteryيقول | |
| 205 | |
| 00:17:53,680 --> 00:17:56,220 | |
| الـ middle cerebral artery it is the largest | |
| 206 | |
| 00:17:56,220 --> 00:18:01,260 | |
| branch of the internal carotid artery ممكن يجي | |
| 207 | |
| 00:18:01,260 --> 00:18:07,000 | |
| سؤال تاني مين فيهم medial branch ومين فيهم lateral | |
| 208 | |
| 00:18:07,000 --> 00:18:15,060 | |
| branch ال anterior cerebral artery يعتبر a medial | |
| 209 | |
| 00:18:15,060 --> 00:18:17,240 | |
| branch | |
| 210 | |
| 00:18:18,530 --> 00:18:22,370 | |
| Media Large Branch والـ Middle Cerebral artery | |
| 211 | |
| 00:18:22,370 --> 00:18:28,610 | |
| Lateral Branchتمام ممكن يجي سؤال مين هو ال large | |
| 212 | |
| 00:18:28,610 --> 00:18:32,590 | |
| medial branch of internal carotid artery ع السليله | |
| 213 | |
| 00:18:32,590 --> 00:18:36,270 | |
| بغز ع وين؟ anterior cerebral artery طب اجي سؤال | |
| 214 | |
| 00:18:36,270 --> 00:18:39,730 | |
| ثاني مين هو ال large ماقولناش largest large | |
| 215 | |
| 00:18:39,730 --> 00:18:43,590 | |
| lateral branch of internal carotid artery بغز ع | |
| 216 | |
| 00:18:43,590 --> 00:18:46,650 | |
| السليله وين؟ ال middle cerebral artery لكن لو اجي | |
| 217 | |
| 00:18:46,650 --> 00:18:51,980 | |
| سؤال مين هو ال largest؟ اكبر واحدفي branches of | |
| 218 | |
| 00:18:51,980 --> 00:18:55,460 | |
| internal carotid artery اكيد رح يكون middle | |
| 219 | |
| 00:18:55,460 --> 00:18:59,740 | |
| cerebral artery و اكتر شريان بيغدى ال brain هو | |
| 220 | |
| 00:18:59,740 --> 00:19:09,080 | |
| middle cerebral artery middle cerebral artery هنا | |
| 221 | |
| 00:19:09,080 --> 00:19:16,800 | |
| ان ال internal carotid artery اعطانا | |
| 222 | |
| 00:19:16,800 --> 00:19:17,520 | |
| اللي هو | |
| 223 | |
| 00:19:20,360 --> 00:19:23,780 | |
| انا واضح عندي بوستيرو كوميونيكاتنج وواضح اللي هو | |
| 224 | |
| 00:19:23,780 --> 00:19:29,840 | |
| middle cerebral artery بيروح لاترال وواضح عندي ايه | |
| 225 | |
| 00:19:29,840 --> 00:19:34,940 | |
| anterior cerebral artery medial ففي صورة ثانية راح | |
| 226 | |
| 00:19:34,940 --> 00:19:44,760 | |
| نشوفهم أفضل ونرسم كل شريان لواحده نبدأ | |
| 227 | |
| 00:19:44,760 --> 00:19:52,380 | |
| ب of Thalmicbranch أو افثالمك افثالمك افثالمك | |
| 228 | |
| 00:19:52,380 --> 00:19:52,820 | |
| افثالمك افثالمك افثالمك افثالمك افثالمك افثالمك | |

| 234 | |
| 00:20:15,030 --> 00:20:20,090 | |
| بغد ال orbit contents and it gives central retinal | |
| 235 | |
| 00:20:20,090 --> 00:20:23,710 | |
| artery هذا ال central retinal artery لو حدث فيه | |
| 236 | |
| 00:20:23,710 --> 00:20:27,390 | |
| occlusion او انسداد اثناء جلطة دماغية ممكن يؤدي | |
| 237 | |
| 00:20:27,390 --> 00:20:31,830 | |
| الى ipsy lateral blindness والمريض يفقد النظر على | |
| 238 | |
| 00:20:31,830 --> 00:20:41,230 | |
| نفس الجهة هي ان ال internal carotid artery خرج منه | |
| 239 | |
| 00:20:41,230 --> 00:20:47,500 | |
| branch اسمهوPhthalmic artery which supply the | |
| 240 | |
| 00:20:47,500 --> 00:20:56,560 | |
| orbit content and it givesCentral Retinal Artery | |
| 241 | |
| 00:20:56,560 --> 00:21:01,420 | |
| هذا هو Central Retinal Artery وهذا أول فرع لـ | |
| 242 | |
| 00:21:01,420 --> 00:21:05,120 | |
| Internal Carotid Artery اسمه ايه؟ Ophthalmic | |
| 243 | |
| 00:21:05,120 --> 00:21:08,140 | |
| Artery Ophthalmic Artery يبقى Ophthalmic Artery | |
| 244 | |
| 00:21:08,140 --> 00:21:13,500 | |
| supply the orbit content and it gives Central | |
| 245 | |
| 00:21:13,500 --> 00:21:16,900 | |
| Retinal Artery يعني شريان الشبكية المركزي | |
| 246 | |
| 00:21:19,880 --> 00:21:24,420 | |
| خلصنا أول فرع من الأفرع تبعات الشريان السباتي | |
| 247 | |
| 00:21:24,420 --> 00:21:28,780 | |
| الداخلي اللي هو Internal Carotid Artery ننتج إلى | |
| 248 | |
| 00:21:28,780 --> 00:21:36,460 | |
| الشريان الثاني Posterior Communicating Artery مين | |
| 249 | |
| 00:21:36,460 --> 00:21:41,320 | |
| اسمه؟ Posterior متجه إلى Posterior Cerebral Artery | |
| 250 | |
| 00:21:41,320 --> 00:21:43,640 | |
| لسه مااخدناهوش راح ناخده في الجزء الثاني من | |
| 251 | |
| 00:21:43,640 --> 00:21:46,520 | |
| المحاضرة اللي هو بيعتبر برانش من الـ A-Vertebral | |
| 252 | |
| 00:21:46,520 --> 00:21:51,540 | |
| Basilar Arteryبستيريور متجه إلى وين؟ للبستيريور | |
| 253 | |
| 00:21:51,540 --> 00:21:56,760 | |
| سريبرال آرتي communicating يعني بيعمل عملية وصل | |
| 254 | |
| 00:21:56,760 --> 00:22:01,460 | |
| بين ال internal carotid artery and posterior | |
| 255 | |
| 00:22:01,460 --> 00:22:04,480 | |
| cerebral artery وان شاء الله راح ناخد اليوم ان | |
| 256 | |
| 00:22:04,480 --> 00:22:08,700 | |
| البستيريور سريبرال آرتي هو يعتبر branch من وين؟ من | |
| 257 | |
| 00:22:08,700 --> 00:22:12,960 | |
| ال vertebro basilar artery في الحالة دي the main | |
| 258 | |
| 00:22:12,960 --> 00:22:21,010 | |
| function ofPosterior Communicating Artery is | |
| 259 | |
| 00:22:21,010 --> 00:22:27,810 | |
| connection between the internal carotid artery | |
| 260 | |
| 00:22:27,810 --> 00:22:32,230 | |
| with posterior | |
| 261 | |
| 00:22:32,230 --> 00:22:36,170 | |
| cerebral artery يعني لو قلنا Right Posterior | |
| 262 | |
| 00:22:36,170 --> 00:22:41,210 | |
| Communicating Artery بربط بين Right Internal | |
| 263 | |
| 00:22:41,210 --> 00:22:49,550 | |
| Carotid Arteryمع مين؟ مع Right Posterior Cerebral | |
| 264 | |
| 00:22:49,550 --> 00:22:59,030 | |
| Artery Right Posterior | |
| 265 | |
| 00:22:59,030 --> 00:23:03,670 | |
| Cerebral Artery وهي Right Internal Carotid Artery | |
| 266 | |
| 00:23:03,670 --> 00:23:08,170 | |
| هذا الشريان اللي بيربطه مع بعض، إيش اسمه؟ | |
| 267 | |
| 00:23:12,170 --> 00:23:24,090 | |
| اسمه posterior communicating | |
| 268 | |
| 00:23:24,090 --> 00:23:27,630 | |
| artery | |
| 269 | |
| 00:23:28,080 --> 00:23:32,380 | |
| بعمل connections ما بين right internal carotid | |
| 270 | |
| 00:23:32,380 --> 00:23:45,620 | |
| artery مع right posterior | |
| 271 | |
| 00:23:45,620 --> 00:23:51,290 | |
| cerebral artery يعني بلغة ثانيةmake connections | |
| 272 | |
| 00:23:51,290 --> 00:23:56,030 | |
| between the carotid system with vertebral basilar | |
| 273 | |
| 00:23:56,030 --> 00:23:58,890 | |
| system يعني بيعمل connection بين ال internal | |
| 274 | |
| 00:23:58,890 --> 00:24:03,170 | |
| carotid system مع مين؟ مع vertebral basilar system | |
| 275 | |
| 00:24:03,170 --> 00:24:10,050 | |
| to establish عشان يكونلنا شيء اسمه circle of | |
| 276 | |
| 00:24:10,050 --> 00:24:13,810 | |
| wheels circle of wheels يبقى مين اللي بيكون ال | |
| 277 | |
| 00:24:13,810 --> 00:24:18,200 | |
| circle of wheels اللي هو ايه؟Posterior | |
| 278 | |
| 00:24:18,200 --> 00:24:21,560 | |
| communicating artery مع شرايين أخرى راح نتطرقلهم | |
| 279 | |
| 00:24:21,560 --> 00:24:27,180 | |
| في نهاية المحاضرة Also it supplies غير أنه ال main | |
| 280 | |
| 00:24:27,180 --> 00:24:30,460 | |
| function لو سألكوا سؤال what's the main function | |
| 281 | |
| 00:24:30,460 --> 00:24:34,980 | |
| of posterior communicating artery the main | |
| 282 | |
| 00:24:34,980 --> 00:24:38,800 | |
| function of posterior communicating artery is | |
| 283 | |
| 00:24:39,800 --> 00:24:45,140 | |
| connection between the internal carotid artery | |
| 284 | |
| 00:24:45,140 --> 00:24:49,980 | |

| 00:33:54,090 --> 00:33:57,190 | |
| أكثر ويه؟ راح يكون في ال lower limbs لأن ال lower | |
| 393 | |
| 00:33:57,190 --> 00:33:59,730 | |
| limbs اتأثرت وين ما كانها في الدماغ ال lower | |
| 394 | |

| 395 | |
| 00:34:03,550 --> 00:34:06,570 | |
| ال head و الإلسان وين ما كانهم؟ في ال inferior | |
| 396 | |
| 00:34:07,780 --> 00:34:10,740 | |
| Lateral، طب و ال upper limbs وين مكانهم في الدماغ؟ | |
| 397 | |
| 00:34:10,740 --> 00:34:13,680 | |
| بيكونوا في ال middle frontal إذا من ناحية إيش | |
| 398 | |
| 00:34:13,680 --> 00:34:17,520 | |
| motor أو middle parietal إذا من ناحية إيه sensory | |
| 399 | |
| 00:34:17,520 --> 00:34:20,400 | |
| يعني يعني ال area المسئولة عن ال lower limbs | |
| 400 | |
| 00:34:20,400 --> 00:34:24,180 | |
| بيغضيها anterior cerebral artery و ال area | |
| 401 | |

| sulcus البراية الـ occipital sulcus الجزء الخلفي | |
| 408 | |
| 00:35:08,740 --> 00:35:12,380 | |
| أو الـ occipital area بتأخد blood supply من وين؟ | |
| 409 | |
| 00:35:12,380 --> 00:35:16,480 | |
| من posterior cerebral artery من وين؟ من posterior | |
| 410 | |
| 00:35:16,480 --> 00:35:22,160 | |
| cerebral artery اللي بيأخد أو الجزء اللي بتغدى ال | |
| 411 | |
| 00:35:22,160 --> 00:35:27,340 | |
| medial هذا جاي من وين؟ من anterior cerebral artery | |
| 412 | |
| 00:35:42,080 --> 00:35:49,460 | |
| هنا واضح الصورة ها هاي left anterior | |
| 413 | |

| Middle cerebral artery is the lateral branch of a | |
| 418 | |
| 00:36:16,240 --> 00:36:20,020 | |
| internal carotid artery يبقى عندنا two large | |
| 419 | |
| 00:36:20,020 --> 00:36:23,460 | |
| branches فيه medial branch large هو anterior | |
| 420 | |
| 00:36:23,460 --> 00:36:27,240 | |
| cerebral artery وفيه lateral branch large هو | |
| 421 | |
| 00:36:27,240 --> 00:36:29,500 | |
| middle cerebral artery لكن لو سألنا سؤال من هو ال | |
| 422 | |
| 00:36:29,500 --> 00:36:34,260 | |
| largest branch هو middle cerebral arteryوهي بيفوت | |
| 423 | |
| 00:36:34,260 --> 00:36:37,060 | |
| في lateral sulcus عشان هيك قلنا هو يعتبر lateral | |
| 424 | |
| 00:36:37,060 --> 00:36:43,680 | |
| branch lateral branch وبيعطينا carotid branches | |
| 425 | |
| 00:36:43,680 --> 00:36:48,740 | |
| and central branches و ال central branches نفس | |
| 426 | |
| 00:36:48,740 --> 00:36:52,660 | |
| الشيء بنسميهم striate branches لأنهم بيغدوا البيزا | |

| 00:36:52,660 --> 00:36:56,780 | |
| النوكلياعي الان | |
| 428 | |
| 00:36:56,780 --> 00:37:00,720 | |
| بتكلم على cortical branches ال cortical branches | |
| 429 | |
| 00:37:00,720 --> 00:37:06,680 | |
| بيغدوا أيه القشرة الدماغاتفقنا ان الـ anterior | |
| 430 | |
| 00:37:06,680 --> 00:37:10,660 | |
| cerebral artery بيغدينا ال superior lateral part | |
| 431 | |
| 00:37:10,660 --> 00:37:16,240 | |
| طب ال middle cerebral artery بيغدي lateral two | |
| 432 | |
| 00:37:16,240 --> 00:37:21,400 | |
| thirdof أو كمان مرة الـ anterior cerebral artery | |
| 433 | |
| 00:37:21,400 --> 00:37:24,680 | |
| قلنا بيغدى ال media ال one third of orbital part | |
| 434 | |
| 00:37:24,680 --> 00:37:28,600 | |
| of frontal lobe ال middle cerebral artery راح يغدى | |
| 435 | |
| 00:37:28,600 --> 00:37:34,080 | |
| lateral to third of the orbital part of frontal | |
| 436 | |
| 00:37:34,080 --> 00:37:40,100 | |
| lobe بيغدى ال temporal pool و ال insula طيب قلنا | |
| 437 | |
| 00:37:40,100 --> 00:37:43,740 | |
| ال anterior cerebral artery بيغدى ال upper | |
| 438 | |
| 00:37:43,740 --> 00:37:49,680 | |
| superior lateral partفي الحالة هذه الـ middle | |
| 439 | |
| 00:37:49,680 --> 00:37:55,820 | |
| cerebral artery بيغضي most of the lateral cerebral | |
| 440 | |
| 00:37:55,820 --> 00:38:00,040 | |
| hemisphere بيغضي most of the lateral cerebral | |
| 441 | |
| 00:38:00,040 --> 00:38:05,460 | |
| hemisphere مع ده except upper part ال upper part | |
| 442 | |
| 00:38:05,460 --> 00:38:08,520 | |
| ال super lateral قولنا باخد وين شرحنا من ال | |
| 443 | |
| 00:38:08,520 --> 00:38:12,460 | |
| anterior cerebral artery ال lower part تبع ال | |
| 444 | |
| 00:38:12,460 --> 00:38:15,900 | |
| timbral loop باخد من ال posterior cerebral artery | |
| 445 | |
| 00:38:16,790 --> 00:38:20,510 | |
| والـ occipital loop بتاخد من وين؟ من posterior | |
| 446 | |
| 00:38:20,510 --> 00:38:23,630 | |
| cerebral artery يعني ال middle cerebral artery | |
| 447 | |
| 00:38:23,630 --> 00:38:26,930 | |
| بيغضي أن كل ال lateral surface of cerebral | |
| 448 | |
| 00:38:26,930 --> 00:38:30,690 | |
| الهيمسفير معدى ال superior lateral الجزء العلوي | |
| 449 | |
| 00:38:30,690 --> 00:38:34,590 | |
| بياخد من ال anterior cerebral artery تمام و ال | |
| 450 | |
| 00:38:34,590 --> 00:38:38,130 | |
| occipital loop بتاخد من ال posterior cerebral | |
| 451 | |
| 00:38:38,130 --> 00:38:42,670 | |
| artery و ال lower temporal loop بتاخد من وين؟ من | |
| 452 | |
| 00:38:42,670 --> 00:38:45,070 | |
| posterior cerebral artery | |
| 453 | |
| 00:38:48,800 --> 00:38:52,200 | |
| Central branches of the middle cerebral artery | |
| 454 | |
| 00:38:52,200 --> 00:38:56,780 | |
| بيغدو بيزل نوكلياي Internal capsule خاصة لـ | |
| 455 | |
| 00:38:56,780 --> 00:39:01,290 | |
| posterior part of internal capsule والجينيوone of | |
| 456 | |
| 00:39:01,290 --> 00:39:04,570 | |
| these arteries is large في واحد منهم شريان كبير | |
| 457 | |
| 00:39:04,570 --> 00:39:09,350 | |
| هذا الشريان بيسموه artery of hemorrhage artery of | |
| 458 | |
| 00:39:09,350 --> 00:39:12,650 | |
| cerebral hemorrhage او اللي اسمه تشاركوت ارتريه | |
| 459 | |
| 00:39:12,650 --> 00:39:15,790 | |
| راح ناخده ان شاء الله في سنة رابعة لما نتكلم على | |
| 460 | |
| 00:39:15,790 --> 00:39:19,230 | |
| محاضرة ال cerebral hemorrhage او النزيف الدماغي | |
| 461 | |
| 00:39:19,230 --> 00:39:24,510 | |
| الشريان هذا كثير بيصير فيه حالات نزيف و ليه بيصير | |
| 462 | |
| 00:39:24,510 --> 00:39:29,510 | |
| فيه نزيف لأن ال smooth muscle layer thin وUnder | |
| 463 | |
| 00:39:29,510 --> 00:39:33,690 | |
| high blood pressure بيحدث له ربشر وبيقدي الى | |
| 464 | |
| 00:39:33,690 --> 00:39:42,030 | |
| Intracerebral Hemorrhage هاي عندي middle cerebral | |
| 465 | |
| 00:39:42,030 --> 00:39:50,490 | |
| artery تعتبر lateral branch Lateral Branch هاي | |
| 466 | |
| 00:39:50,490 --> 00:39:54,650 | |
| و أنا أجانوين في lateral sulcus او lateral fissure | |
| 467 | |
| 00:39:54,650 --> 00:40:00,900 | |
| وبيغضي ايه اللي هي موسCerebral هي مصير المعدة | |
| 468 | |
| 00:40:00,900 --> 00:40:07,660 | |
| الجزء العلوي تأخذ من أنتريو سيريبرال آرتري | |
| 469 | |
| 00:40:07,660 --> 00:40:13,760 | |
| الأكسيبيتال تأخذ من بوستيريو سيريبرال آرتري | |
| 470 | |
| 00:40:13,760 --> 00:40:18,040 | |
| والإنفيريور سيرفيس بتاعة ال timber loop تأخذ من | |
| 471 | |
| 00:40:18,040 --> 00:40:19,860 | |
| بوستيريو سيريبرال آرتري | |
| 472 | |
| 00:40:37,540 --> 00:40:41,640 | |
| هي واضح عندي في الصورة هذه اللي هو middle cerebral | |
| 473 | |
| 00:40:41,640 --> 00:40:46,180 | |
| artery as lateral branch إله cortical branches | |
| 474 | |
| 00:40:46,180 --> 00:40:50,560 | |
| وإله إيه هنا نسميهم central branches اللي هم | |
| 475 | |
| 00:40:50,560 --> 00:40:56,400 | |
| أسريات ال branches | |
| 476 | |
| 00:40:56,400 --> 00:41:01,180 | |
| واضح | |
| 477 | |
| 00:41:01,180 --> 00:41:05,040 | |
| حلو هنا عندي ال middle cerebral artery إله lateral | |
| 478 | |
| 00:41:05,040 --> 00:41:10,830 | |
| branchesوالو central branches اللي هما striate | |
| 479 | |
| 00:41:10,830 --> 00:41:17,090 | |
| arteries في منهم short striate artery واضحين هنا | |
| 480 | |
| 00:41:17,090 --> 00:41:22,070 | |
| short striate arteries وفي long striate arteries | |
| 481 | |
| 00:41:26,090 --> 00:41:28,990 | |
| واحد منهم دول الشرايين لسرية الارتريز بيكون | |
| 482 | |
| 00:41:28,990 --> 00:41:33,050 | |
| labelled to bleeding واسمه artery of cerebral | |
| 483 | |
| 00:41:33,050 --> 00:41:37,510 | |
| hemorrhage او بنسميه charcoal artery لذلك اكتر | |
| 484 | |
| 00:41:37,510 --> 00:41:43,520 | |
| مكان بيحدث فيه نزيف دماغي هو ال basal nucleiلحد | |
| 485 | |
| 00:41:43,520 --> 00:41:47,420 | |
| الآن بن .. بن اكتفي في الجزء الأول من المحاضرة، | |
| 486 | |
| 00:41:47,420 --> 00:41:50,240 | |
| الجزء الثاني ان شاء الله من المحاضرة راح يكون على | |
| 487 | |
| 00:41:50,240 --> 00:41:54,700 | |
| vertebral basilar system هو ال diural venous | |
| 488 | |
| 00:41:54,700 --> 00:41:56,960 | |
| drainage، يعطيكوا العافية | |
