00:00:07,540 --> 00:00:13,840
وبركاته الجزء الثاني من محاضرة الأسبوع الخامس رح 

3
00:00:13,840 --> 00:00:18,200
تكون على ventricles of the brain and CSF 

4
00:00:18,200 --> 00:00:24,430
circulation. The brain and spinal cord float within

5
00:00:24,430 --> 00:00:30,170
a protective bath of cerebrospinal fluid. الدماغ و

6
00:00:30,170 --> 00:00:38,810
الحبل الشوكي بيسبحوا في حوض من السائل الدماغي 

7
00:00:38,810 --> 00:00:46,040
الشوكي. CSF is produced by the choroidal plexus 

8
00:00:46,040 --> 00:00:49,960
واحنا عارفين في ال ventricular system في ال

9
00:00:49,960 --> 00:00:53,640
choroidal plexus أصلها جاية من invagination of the

10
00:00:53,640 --> 00:00:59,920
pia mater و ال choroidal plexus contains ependymal

11
00:00:59,920 --> 00:01:03,140
cells و ال ependymal cells تقوم بـ production لـ ال

12
00:01:03,140 --> 00:01:09,410
CSF. Each part of the central nervous system contains

13
00:01:09,410 --> 00:01:14,210
a component of the ventricular system. يعني لو 

14
00:01:14,210 --> 00:01:18,530
اتكلمنا على ال cerebral hemisphere في lateral

15
00:01:18,530 --> 00:01:23,250
ventricle، diencephalon في third ventricle، في

16
00:01:23,250 --> 00:01:26,510
الcerebellum و المَـدُلة و ال pons في fourth

17
00:01:26,510 --> 00:01:31,510
ventricle، في ال midbrain في silvius aqueduct أو

18
00:01:31,510 --> 00:01:37,470
بنسميها cerebral aqueduct. الـ ventricles contain

19
00:01:37,470 --> 00:01:46,150
about 35 milliliter of cerebrospinal fluid. The 

20
00:01:46,150 --> 00:01:50,850
ventricles of the brain there 

21
00:01:50,850 --> 00:01:54,310
are four interconnected ventricles of the brain.

22
00:01:54,310 --> 00:02:00,410
في عندنا four ventricles. lateral ventricles البطين 

23
00:02:00,410 --> 00:02:05,900
الجانبي right and left lateral ventricle. third

24
00:02:05,900 --> 00:02:11,700
ventricle. البطين الثالث and fourth ventricle

25
00:02:11,700 --> 00:02:17,220
البطين الرابع. يبقى عندنا four interconnected

26
00:02:17,220 --> 00:02:22,980
ventricles. two lateral ventricles and one third

27
00:02:22,980 --> 00:02:30,720
ventricle and a fourth ventricle. اللحظة هنا عندي 

28
00:02:30,720 --> 00:02:33,800
lateral ventricle.

29
00:02:36,730 --> 00:02:42,830
left and right lateral ventricle. بعدها بيجي third 

30
00:02:42,830 --> 00:02:47,870
ventricle وفي الآخر في عندي ايه؟ fourth ventricle.

31
00:02:47,870 --> 00:02:56,530
هنا عندي في الصورة واضح cavity

32
00:02:56,530 --> 00:03:03,090
of right lateral ventricle. بعدين هنا في بتكون 

33
00:03:03,090 --> 00:03:09,820
cavity of third ventricle. وهنا فيه اللي هي cavity 

34
00:03:09,820 --> 00:03:15,940
of a fourth ventricle. و ال connection القناة اللي 

35
00:03:15,940 --> 00:03:20,520
بتوصل ما بين ال third ventricle و ال fourth 

36
00:03:20,520 --> 00:03:26,520
ventricle اسمها silvius aqueduct أو cerebral

37
00:03:26,520 --> 00:03:33,270
aqueduct. اسمها silvius aqueduct أو cerebral

38
00:03:33,270 --> 00:03:48,290
aqueduct أو بنسميها aqueduct of midbrain. نبدأ 

39
00:03:48,290 --> 00:03:53,270
بـ lateral ventricle. لدينا two lateral ventricles.

40
00:03:53,270 --> 00:03:58,510
right and left lateral ventricles side.

41
00:03:59,940 --> 00:04:03,360
lateral ventricles عبارة عن cavity of cerebral

42
00:04:03,360 --> 00:04:06,660
hemispheres. يعني انها right cerebral hemisphere و

43
00:04:06,660 --> 00:04:10,120
left cerebral hemisphere. كل cerebral hemisphere

44
00:04:10,120 --> 00:04:12,660
اللي لهم cavity اسمه lateral ventricles. يعني انها

45
00:04:12,660 --> 00:04:16,700
right and left lateral ventricles. لو اتكلمنا عن ال

46
00:04:16,700 --> 00:04:22,400
origin of lateral

47
00:04:22,400 --> 00:04:25,600
ventricles بيكون جاي من telencephalon أو 

48
00:04:25,600 --> 00:04:28,820
prosencephalon. communication 

49
00:04:31,580 --> 00:04:41,000
no any direct connections between right and left

50
00:04:41,000 --> 00:04:44,480
lateral ventricles. يعني مافي انها direct

51
00:04:44,480 --> 00:04:46,820
connection between right and left lateral 

52
00:04:46,820 --> 00:04:53,260
ventricle. نرسمهم مع بعض الآن. هي ان انا برسم

53
00:05:24,530 --> 00:05:33,650
أنا رسمت right وهي برسم فيه left lateral 

54
00:05:33,650 --> 00:05:35,250
ventricle. يعني عندي 

55
00:05:44,560 --> 00:05:56,420
right lateral ventricle و left lateral ventricle.

56
00:05:56,420 --> 00:06:02,540
okay. no direct connection between both lateral 

57
00:06:02,540 --> 00:06:05,460
ventricles. تمام. بعدها بدنا نرسم

58
00:06:11,790 --> 00:06:13,170
third ventricle.

59
00:06:36,980 --> 00:06:42,700
بين ال lateral ventricle و ال third ventricle في 

60
00:06:42,700 --> 00:06:51,760
foramen. left interventricular foramen of Monro و

61
00:06:51,760 --> 00:06:59,320
هنا في right interventricular foramen of Monro.

62
00:06:59,320 --> 00:07:05,210
يعني احنا رسلنا left lateral ventricle و right

63
00:07:05,210 --> 00:07:09,010
lateral ventricle و رسمنا third ventricle. no

64
00:07:09,010 --> 00:07:12,630
direct connection between both lateral ventricles

65
00:07:12,630 --> 00:07:18,170
but presented indirect connection. من خلال ايه؟ 

66
00:07:19,470 --> 00:07:23,570
interventricular foramen of Monro. كم Monro فينا؟

67
00:07:23,570 --> 00:07:28,050
فينا two foramen of Monro. فينا left foramen of 

68
00:07:28,050 --> 00:07:32,150
Monro و في right foramen of Monro. يبقى ال

69
00:07:32,150 --> 00:07:36,410
communication بتاع ال lateral ventricle. H lateral

70
00:07:36,410 --> 00:07:41,410
ventricle communicates with the third ventricle

71
00:07:41,410 --> 00:07:45,770
through interventricular foramen of Monro. right 

72
00:07:45,770 --> 00:07:46,510
and left.

73
00:07:50,300 --> 00:07:53,360
What's the part of the lateral ventricle؟ إيش 

74
00:07:53,360 --> 00:07:56,220
أجزاء ال lateral ventricle؟ ال lateral ventricle 

75
00:07:56,220 --> 00:08:02,140
contains anterior horn أو frontal horn. located in 

76
00:08:02,140 --> 00:08:08,180
frontal lobe، posterior horn أو occipital horn

77
00:08:08,180 --> 00:08:13,330
located in occipital lobe، inferior horn أو

78
00:08:13,330 --> 00:08:17,690
temporal horn. located in temporal lobe. مين راح 

79
00:08:17,690 --> 00:08:21,550
يزعل؟ ال parietal lobe ما يزعلش. ال parietal lobe و

80
00:08:21,550 --> 00:08:26,270
في جزء اسمه body أو central part of the lateral

81
00:08:26,270 --> 00:08:30,990
ventricle which is located in the parietal lobe. و

82
00:08:30,990 --> 00:08:36,530
في شيء اسمه trigon أو atrium. دي dilation at the

83
00:08:36,530 --> 00:08:41,070
meeting of the inferior and posterior horn. وين

84
00:08:41,070 --> 00:08:44,570
بتقابل ال anterior و ال posterior horn. نشوف مع بعض 

85
00:08:44,570 --> 00:08:51,390
على الصورة. هنا في الخلف عندي هنا posterior horn

86
00:08:51,390 --> 00:09:00,210
posterior horn و في الأمام بيكون anterior horn. وهنا 

87
00:09:00,210 --> 00:09:05,570
إيش ال body أو ال central part. body أو ال central 

88
00:09:05,570 --> 00:09:09,330
part مش هينبين انها الأجزاء الثانية. يعني يعني عندي

89
00:09:09,330 --> 00:09:12,310
في posterior horn بتكون في ال occipital lobe. في

90
00:09:12,310 --> 00:09:16,070
anterior horn بتكون في ال frontal lobe وفي body 

91
00:09:16,070 --> 00:09:25,330
بتكون في parietal lobe. في parietal lobe. واضح 

92
00:09:25,330 --> 00:09:25,770
عندي هنا 

93
00:09:28,940 --> 00:09:34,000
anterior horn, posterior horn، و تحت في ال temporal 

94
00:09:34,000 --> 00:09:40,630
lobe في inferior horn. يعني frontal horn، occipital 

95
00:09:40,630 --> 00:09:45,310
horn، temporal horn. أو اسم ثاني: anterior horn،

96
00:09:45,310 --> 00:09:50,550
posterior horn، inferior horn. طب و المكان تلاقي 

97
00:09:50,550 --> 00:09:54,790
الـ inferior horn مع الـ posterior horn. هذا المكان 

98
00:09:54,790 --> 00:10:01,470
بنسميه trigon، بنسميه trigon أو atrium of lateral

99
00:10:01,470 --> 00:10:02,290
ventricle.

100
00:10:08,870 --> 00:10:15,950
لاحظوا هنا على شاشة تلفزيون عندي anterior horn,

101
00:10:17,650 --> 00:10:26,870
posterior horn, inferior horn, body، و هذا المكان 

102
00:10:26,870 --> 00:10:34,830
بنسميه atrium أو trigon. هو مكان تلاقي ال posterior

103
00:10:34,830 --> 00:10:38,510
horn مع ال inferior horn، لكن الأصح لو قلنا أصح 

104
00:10:38,510 --> 00:10:45,310
كمان هو عبارة عن تلاقي ما بين posterior horn مع ال

105
00:10:45,310 --> 00:10:51,140
inferior horn و ال body. مكان بتلاقى فيه ال body مع 

106
00:10:51,140 --> 00:10:53,140
ال posterior horn و ال inferior horn. لكن الكتب 

107
00:10:53,140 --> 00:10:56,240
بيكتبوا هو عبارة عن مكان وين بتلاقى فيه ال

108
00:10:56,240 --> 00:10:59,860
posterior horn مع ال inferior horn. الأصح تلاقي ما

109
00:10:59,860 --> 00:11:05,240
بين posterior horn و inferior horn and body of 

110
00:11:05,240 --> 00:11:09,060
lateral ventricle and body of lateral ventricle.

111
00:11:09,060 --> 00:11:16,710
لاحظوا هنا في foramen. هنا واحد، اثنين. واحد بيكون مع ال 

112
00:11:16,710 --> 00:11:18,430
left lateral ventricle و مع ال right lateral

113
00:11:18,430 --> 00:11:21,810
ventricle. هذول communication مع مين؟ مع ال third 

114
00:11:21,810 --> 00:11:25,390
ventricle. مع ايه؟ مع ال third ventricle. مع ال

115
00:11:25,390 --> 00:11:28,990
third ventricle. اسمه Interventricular Foramen of

116
00:11:28,990 --> 00:11:41,650
Monro. Interventricular Foramen of Monro. هذا 

117
00:11:41,650 --> 00:11:47,320
واضح على ال axial cut. هذا anterior horn و هذا 

118
00:11:47,320 --> 00:11:53,100
posterior horn أو هذا posterior horn و هذا trigon 

119
00:11:53,100 --> 00:12:05,980
أو atrium. تجي هنا trigon أو atrium. ننتقل

120
00:12:05,980 --> 00:12:15,020
الآن لـ third ventricle. third ventricle عبارة عن cavity. هو

121
00:12:15,020 --> 00:12:19,600
cavity of diencephalon. it is a narrow cavity situated

122
00:12:19,600 --> 00:12:25,780
in the midline between the right and left thalamus

123
00:12:25,780 --> 00:12:32,270
و الهيبوثلامس. بين ال right و ال left. في adhesion 

124
00:12:32,270 --> 00:12:36,610
بنسميها interthalamic adhesion. هي هذي اللي أنا 

125
00:12:36,610 --> 00:12:40,230
رسمتها. هي عبارة عن interthalamic adhesion.

126
00:12:40,230 --> 00:12:44,430
interthalamic ايه؟ adhesion. يعني هذا المكان

127
00:12:44,430 --> 00:12:49,730
connection between right and left thalami. okay. ال

128
00:12:49,730 --> 00:12:55,690
origin of third ventricle from diencephalon أو 

129
00:12:55,690 --> 00:12:57,810
كمان صح prosencephalon.

130
00:13:00,320 --> 00:13:07,440
هنا عندي ال axial cut. هذا هو ال third ventricle اللي 

131
00:13:07,440 --> 00:13:11,220
بيجي في النصف من المنتصف و بيحده من الشمال و

132
00:13:11,220 --> 00:13:18,980
اليمين left thalamus و right thalamus. غير هيك بيمر

133
00:13:18,980 --> 00:13:25,240
في شيء اسمه interthalamic adhesion. connections

134
00:13:25,240 --> 00:13:30,200
between left and right ثلامي. يبقى هي عبارة عن 

135
00:13:30,200 --> 00:13:34,340
connection between left and right ثلامي. كام third 

136
00:13:34,340 --> 00:13:38,620
ventricle؟ عندنا one third ventricle. عندنا one

137
00:13:38,620 --> 00:13:44,240
third ventricle. ننتقل لـ communications of third 

138
00:13:44,240 --> 00:13:48,000
ventricle. أول communication أنا اتكلمت عنها 

139
00:13:49,130 --> 00:13:56,090
anterior superiorly. من الأمام ومن أعلى the third 

140
00:13:56,090 --> 00:14:01,690
ventricle communicates with a lateral ventricle.

141
00:14:01,690 --> 00:14:06,570
يعني ال third ventricle communicates with both

142
00:14:06,570 --> 00:14:13,490
lateral ventricles. Okay. كمان مرة اللي هو ال third

143
00:14:13,490 --> 00:14:19,170
ventricle communicates anterior superiorly with 

144
00:14:19,170 --> 00:14:23,910
both lateral ventricles. من طريق ايه؟ أو عن طريق

145
00:14:23,910 --> 00:14:29,270
ايه؟ عن طريق interventricular foramen of Monro. كم 

146
00:14:29,270 --> 00:14:34,070
Monro عندي؟ left and right Monro. يبقى خلصنا من 

147
00:14:34,070 --> 00:14:35,990
الاعلى. طب من أسفل 

148
00:14:40,160 --> 00:14:47,600
Posterior inferiorly. Posterior

149
00:14:47,600 --> 00:14:53,820
inferiorly communicates with fourth ventricle. with 

150
00:14:53,820 --> 00:14:57,220
ايه؟

151
00:14:57,220 --> 00:15:04,940
with fourth ventricle. عن طريق ايه؟ هذه fourth

152
00:15:04,940 --> 00:15:07,680
ventricle.

153
00:15:09,860 --> 00:15:16,180
عن طريق aqueduct أو بنسميه cerebral... cerebral

154
00:15:16,180 --> 00:15:25,180
aqueduct أو له اسم ثاني: silvius aqueduct. يعني 

155
00:15:25,180 --> 00:15:29,400
silvius aqueduct أو cerebral aqueduct تعمل 

156
00:15:29,400 --> 00:15:32,440
connection ما بين ال third ventricle مع ال fourth

157
00:15:32,440 --> 00:15:37,060
كمان مرة نعيد. communication of third ventricle.

158
00:15:38,550 --> 00:15:42,530
anterior superiorly. من الأمام ومن أعلى 

159
00:15:42,530 --> 00:15:45,790

160
00:15:45,790 --> 00:15:51,450
مع both lateral ventricles. عن طريق ايه؟

161
00:15:51,450 --> 00:15:55,670
Interventricular foramen of Monro. two Monro.

162
00:15:55,670 --> 00:16:01,930
اثنين. posterior inferiorly. من الخلف ومن تحت 

163
00:16:01,930 --> 00:16:10,380
communicates with fourth ventricle. عن طريق ايه؟ 

164
00:16:10,380 --> 00:16:15,200
sylvius أو cerebral aqueduct اللي هو يعتبر cavity

165
00:16:15,200 --> 00:16:22,120
of midbrain. cavity of midbrain. هاي عندنا

166
00:16:22,120 --> 00:16:29,880
interthalamic adhesion. هاي Monro foramen. وهي عندي

167
00:16:29,880 --> 00:16:33,880
ايه؟ cerebral aqueduct اللي بربط ما بين 

168
00:16:38,960 --> 00:16:49,740
third ventricle مع مين؟ مع fourth ventricle. و 

169
00:16:49,740 --> 00:17:03,620
anterior superior ليه؟ عندي من عندي 

170
00:17:03,620 --> 00:17:04,280
في ايه؟

00:17:08,720 --> 00:17:13,100
Monro foramen. Right 

172
00:17:13,100 --> 00:17:17,600
and left بيعمل connection بين ال lateral ventricle

173
00:17:17,600 --> 00:17:21,680
مع مين؟ مع ال third ventricle. يعني هي عندي lateral 

174
00:17:21,680 --> 00:17:26,340
ventricles عن طريق Monro ارتبطوا مع ال third 

175
00:17:26,340 --> 00:17:29,800
ventricle. ال third ventricle عن طريق cerebral aqueduct

176
00:17:29,800 --> 00:17:34,710
مع مين؟ مع ال fourth ventricle. هاد ال 

177
00:17:34,710 --> 00:17:40,870
communication between the ventricular system. واضح 

178
00:17:40,870 --> 00:17:45,290
ان دي lateral ventricle communicates مع ال third

179
00:17:45,290 --> 00:17:47,530
ventricle عن طريق interventricular foramen of 

180
00:17:47,530 --> 00:17:51,410
Monro and right and left Monro. بعدين third 

181
00:17:51,410 --> 00:17:54,690
ventricle عن طريق cerebral aqueduct أو sylvius 

182
00:17:54,690 --> 00:17:58,410
aqueduct communicates with ايش؟ with fourth 

183
00:17:58,410 --> 00:17:58,990
ventricle.

184
00:18:19,220 --> 00:18:25,960
الآن بنتقل لل fourth ventricle.

185
00:18:25,960 --> 00:18:31,960
هذا 

186
00:18:31,960 --> 00:18:38,020
left lateral ventricle.

187
00:18:38,020 --> 00:18:42,800
okay. fourth

188
00:18:42,800 --> 00:18:50,070
ventricle. it is cavity of hindbrain و ممكن اقول it

189
00:18:50,070 --> 00:18:55,770
is cavity of rhombencephalon. وين موجود؟ located

190
00:18:55,770 --> 00:19:00,010
between cerebellum 

191
00:19:00,010 --> 00:19:05,470
and pons medulla oblongata. يعني بيحدوا من الخلف 

192
00:19:05,470 --> 00:19:12,990
ال cerebellum و بيحدوا من الأمام ال pons و ال upper 

193
00:19:12,990 --> 00:19:18,170
medulla أو open medulla. طيب بكلام ثاني لو بدي أصيغه 

194
00:19:18,17

201
00:20:05,590 --> 00:20:11,190
superior angle و inferior angle و lateral angle

202
00:20:11,190 --> 00:20:19,030
superior angle بفتح فيه اللي هو the silvius aqueduct

203
00:20:19,030 --> 00:20:24,270
أو the cerebral aqueduct من أعلى ال superior angle

204
00:20:24,270 --> 00:20:30,470
inferior angle بيمر في ال central spinal canal

205
00:20:30,470 --> 00:20:35,530
بيمر في ال closed medulla طيب و ال lateral angle

206
00:20:35,530 --> 00:20:41,470
right and left lateral angle بيمر فيه foramen اسمه

207
00:20:41,470 --> 00:20:45,530
right luschka foramen و left luschka foramen كمان

208
00:20:45,530 --> 00:20:54,110
مرة في عندي superior angle تشوف مع الصورة هيهم هي

209
00:20:54,110 --> 00:21:02,290
superior angle مين فاتح فيه فاتح اللي هو

210
00:21:07,180 --> 00:21:13,880
the cerebral aqueduct هذا في ال superior angle طب في

211
00:21:13,880 --> 00:21:21,020
ال inferior angle هي inferior angle بفتح

212
00:21:21,020 --> 00:21:26,120
فيه the central

213
00:21:26,120 --> 00:21:29,260
central

214
00:21:30,080 --> 00:21:34,500
the Central Spinal Canal اللي بيمر وين؟

215
00:21:34,500 --> 00:21:37,680
أول شي بيمر في الـ Closed Medulla وبعدين بيمر في

216
00:21:37,680 --> 00:21:43,320
the Spinal Cord يبقى عندي Inferior Angle فاتح فيه اللي

217
00:21:43,320 --> 00:21:47,840
هو the Central Spinal Canal وفي Superior Angle فاتح

218
00:21:47,840 --> 00:21:53,520
the Cerebral أو the Silvius Aqueduct وفي عندي Lateral

219
00:21:53,520 --> 00:22:01,080
Angle the Lateral Angle Right and Left lateral angle

220
00:22:01,080 --> 00:22:06,680
بفتح فيهم foramen على ال right اسمه right luschka foramen

221
00:22:06,680 --> 00:22:10,680
وعلى ال left اسمه left luschka foramen يبقى

222
00:22:10,680 --> 00:22:15,120
بالطريقة هذه أنا شرحتلكم ال angles of the fourth

223
00:22:15,120 --> 00:22:22,400
ventricle الآن

224
00:22:22,400 --> 00:22:27,480
صار الموضوع سهل communications of the fourth

225
00:22:27,480 --> 00:22:32,860
ventricle انا اتكلمت عن communication بين ال fourth

226
00:22:32,860 --> 00:22:40,720
ventricle ها هي و ال third ventricle اسمها the silvius

227
00:22:40,720 --> 00:22:44,140
أو the cerebral aqueduct بتكون فاتحة في ال superior

228
00:22:44,140 --> 00:22:49,560
angle طب في ال inferior angle في communications

229
00:22:49,560 --> 00:22:57,400
اسمها the central

230
00:23:01,100 --> 00:23:09,160
spinal canal طيب

231
00:23:09,160 --> 00:23:16,420
في ال lateral angle على ال right و على ال left في

232
00:23:16,420 --> 00:23:24,340
right and left foramina

233
00:23:24,340 --> 00:23:27,720
luschka

234
00:23:30,810 --> 00:23:34,810
طيب في ال media .. بصير ال media في ال .. في ال

235
00:23:34,810 --> 00:23:40,490
report فيها foramen

236
00:23:40,490 --> 00:23:44,670
مجندي

237
00:23:44,670 --> 00:23:50,970
.. foramen مجندي أو مجندي يقول عندي كام صاروا ..

238
00:23:50,970 --> 00:23:54,970
صاروا أربعة صاروا كام foramen أو communication أربعة

239
00:23:55,910 --> 00:24:00,810
the Cerebral Aqueduct أو the Central أو the Sylvius Aqueduct

240
00:24:00,810 --> 00:24:04,690
هو عبارة عن connection between the fourth and the third

241
00:24:04,690 --> 00:24:10,390
ventricle the Central Spinal Canal بيصرف جزء من ال CSF

242
00:24:10,390 --> 00:24:16,800
على ال central spinal canal لمين؟ لل spinal cord و

243
00:24:16,800 --> 00:24:21,160
ثلاثة foramina .. يعني ثلاثة foramina لوشكا foramina

244
00:24:21,160 --> 00:24:24,340
بيكون ال lateral أو ماجيندي foramen بيكون

245
00:24:24,340 --> 00:24:30,450
posterior هدول بيصرفوا ال CSF من ال fourth

246
00:24:30,450 --> 00:24:36,530
ventricle لل subarachnoid space and the subarachnoid

247
00:24:36,530 --> 00:24:40,210
cistern the subarachnoid space and the subarachnoid

248
00:24:40,210 --> 00:24:45,970
cistern واحنا اتفجنا أن ال cistern هي عبارة عن

249
00:24:45,970 --> 00:24:54,690
widening place of the subarachnoid space هاي

250
00:24:54,690 --> 00:24:58,630
ممكن مرة نشرحهم هنا communications أو نشوف صورة

251
00:24:58,630 --> 00:24:58,950
ثانية

252
00:25:02,160 --> 00:25:05,680
هنا واضح هي ال communication بتاعة ال fourth

253
00:25:05,680 --> 00:25:10,960
ventricle نرسم ال fourth ventricle هذا هو ال ايه

254
00:25:10,960 --> 00:25:18,400
fourth ventricle أول

255
00:25:18,400 --> 00:25:22,500
communication مع ال superior angle عن طريق

256
00:25:22,500 --> 00:25:29,040
the cerebral aqueduct أو the sylvius aqueduct هي أول واحد

257
00:25:30,920 --> 00:25:35,680
the Central Spinal Canal في الـ Closed Medulla وبعدين

258
00:25:35,680 --> 00:25:41,900
في the Spinal Cord ثلاثة وأربعة في الـ Lateral بيكون

259
00:25:41,900 --> 00:25:47,740
عندي فرع من the Luschka Right and Left و posteriorly

260
00:25:47,740 --> 00:25:53,070
بيكون فرع من the Magendie السيلفياس اكويداكت أو

261
00:25:53,070 --> 00:25:56,470
the cerebral aqueduct بربط ال third ventricle مع ال

262
00:25:56,470 --> 00:26:03,670
fourth ventricle the Central spinal canal بعمل

263
00:26:03,670 --> 00:26:06,970
connection ما بين ال fourth ventricle مع ال

264
00:26:06,970 --> 00:26:11,090
the central spinal canal بتاعة ال spinal cordفورا من

265
00:26:11,090 --> 00:26:15,370
اللوشكا أو ماجيندي بيصرفوا ال CSF من ال fourth

266
00:26:15,370 --> 00:26:20,010
ventricle لال the subarachnoid space وال the subarachnoid

267
00:26:20,010 --> 00:26:24,190
cistern وقولنا ال cistern هي عبارة عن the widening

268
00:26:24,190 --> 00:26:32,310
place of the subarachnoid space هيك بيكون أنا شرحتلكم

269
00:26:32,310 --> 00:26:39,700
ال ventricular system هاي واضح the sylvius aqueduct أو

270
00:26:39,700 --> 00:26:43,140
the cerebroacviduct واضح عندي the central spinal canal

271
00:26:43,140 --> 00:26:47,720
واضح عن اللوشكا ماجيندي foramen وفي ال lateral

272
00:26:47,720 --> 00:26:54,080
بيكون two luschka foramina the cerebrospinal fluid أخر

273
00:26:54,080 --> 00:26:58,340
جزئية في المحاضرة the cerebrospinal fluid هي عبارة عن

274
00:26:58,340 --> 00:27:04,040
fluid which circulates in the ventricles and the

275
00:27:04,040 --> 00:27:11,200
central canal of the CNS وأيضًا تدفع إلى الـ

276
00:27:11,200 --> 00:27:18,340
the Subarachnoid space الـ production of the CSF بتتم من

277
00:27:18,340 --> 00:27:23,220
ال ependymal cells موجودة في the choroid plexuses of

278
00:27:23,220 --> 00:27:27,560
the lateral third and fourth ventricle لكن أكتر شيء

279
00:27:27,560 --> 00:27:33,410
بيكون في ال lateral ventricle بين دايما بتعمل

280
00:27:33,410 --> 00:27:40,610
extraction أو production لل CSF من ال capillaries

281
00:27:40,610 --> 00:27:45,630
بتاعة ال arteries وبتعمل عملية فلترة وبتخرج ال CSF من

282
00:27:45,630 --> 00:27:48,210
ال blood من ال arterial blood في ال ventricular

283
00:27:48,210 --> 00:27:53,910
system the circulation of the CSF سيبونا من ال slide هذا

284
00:27:53,910 --> 00:27:58,410
نتبع مع بعض على the slide هنا أو بتقول على ال slide

285
00:27:58,410 --> 00:28:01,730
اللي أنا رسمته نفس الشيء على الصورة اللي رسمتها الـ

286
00:28:01,730 --> 00:28:07,190
CSF اللي تم اله production من الـ third ventricle

287
00:28:07,190 --> 00:28:11,910
بعبر عن طريق الـ interventricular foramen of Monro

288
00:28:11,910 --> 00:28:16,690
right and left و بيروح لوين؟ لل third ventricle ها

289
00:28:16,690 --> 00:28:25,090
ايه دخل و راحوا لوين؟ ل .. نرسم بلون ثاني و راحوا

290
00:28:25,090 --> 00:28:29,350
ل .. لل third ventricle

291
00:28:35,420 --> 00:28:39,120
هيو بيسلموا على ال third ventricle و بياخدوا ال

292
00:28:39,120 --> 00:28:43,660
CSF من ال third ventricle و بيدخلوا لوين؟

293
00:28:43,660 --> 00:28:48,640
ل the cerebral aqueduct و

294
00:28:48,640 --> 00:28:53,320
بيروحوا لوين؟ لال third من ال third ventricle

295
00:28:53,320 --> 00:28:57,980
بيروحوا لال fourth ventricle جزء بسيط من ال CSF

296
00:28:58,630 --> 00:29:03,510
بيروح ل the central spinal canal ل the central spinal

297
00:29:03,510 --> 00:29:08,730
canal الجزء الأكبر بيغادر ال ventricles عن طريق

298
00:29:08,730 --> 00:29:12,570
ماجيندي foramina و لوشكا foramina right and left

299
00:29:12,570 --> 00:29:17,710
بيغادروا من لوشكا و من ماجيندي foramina و أين

300
00:29:17,710 --> 00:29:25,070
بيطلعوا؟ ال the subarachnoid space of the brain and the

301
00:29:25,070 --> 00:29:30,710
subarachnoid space of the spinal cord هيك بالطريقة هذه

302
00:29:30,710 --> 00:29:35,570
أنا شرحتلكوا كله على ال slide واضح و سلس و سهل و

303
00:29:35,570 --> 00:29:42,250
مش صعب نتبع

304
00:29:42,250 --> 00:29:46,850
مع بعض السلس اللي جابنا نشوفه The CSF in each

305
00:29:46,850 --> 00:29:49,490
lateral ventricle بيمورف الـ the Interventricular

306
00:29:49,490 --> 00:29:54,010
Foramen of Monroe بعد ذلك للثيرد Ventricle عن طريق

307
00:29:54,010 --> 00:29:58,090
the Aqueduct of Silvius أو the Silvius Aqueduct بيمورفيه

308
00:29:58,090 --> 00:30:02,110
وبعدها بنتجل لل fourth ventricle جزء من ال CSF

309
00:30:02,110 --> 00:30:06,090
بيروح لل the Central Spinal Canal والجزء الأكبر بيروح

310
00:30:06,090 --> 00:30:10,230
عن طريق ثلاثة foramina ماجيندي و لوشكا foramina

311
00:30:10,230 --> 00:30:14,930
بيروح لها ال the subarachnoid space و ال the subarachnoid

312
00:30:14,930 --> 00:30:19,150
cistern من ضمنهم the cerebellum medullary cistern و

313
00:30:19,150 --> 00:30:23,590
pontine cistern كمان هدول موجودين في ال the subarachnoid

314
00:30:23,590 --> 00:30:28,740
space منهم بيروح لل the subarachnoid space بتاعة ال

315
00:30:28,740 --> 00:30:32,500
brain وال the spinal cord هيك بيكون عاملنا واتكلمنا

316
00:30:32,500 --> 00:30:38,570
على ال circulation of the CSF طب absorption of the CSF؟ ال

317
00:30:38,570 --> 00:30:43,390
absorption of the CSF بتتم عن طريق اللي هي the arachnoid

318
00:30:43,390 --> 00:30:47,370
villi and the arachnoid granulation شرحت لكم بيام في

319
00:30:47,370 --> 00:30:51,350
the arachnoid مطر و بيتم absorption و reabsorption

320
00:30:51,350 --> 00:30:56,050
بتاعة ال CSF لل the dural venous sinuses و من ال

321
00:30:56,050 --> 00:30:58,910
the dural venous sinuses بتروح على ال the jugular vein و

322
00:30:58,910 --> 00:31:02,430
منهم بتروح على ال the venous blood و ال the venous blood

323
00:31:02,430 --> 00:31:10,100
stream لل the right atrium of the heart هذا واضح

324
00:31:10,100 --> 00:31:13,560
عندي اللي هم the arachnoid granulation الـ the arachnoid

325
00:31:13,560 --> 00:31:16,300
villi بيكونوا microscopic بياخدوا ال CSF من ال the sub

326
00:31:16,300 --> 00:31:19,660
the arachnoid space و بيسلموه لل the dural venous sinuses

327
00:31:19,660 --> 00:31:23,700
what's the function of the CSF؟ ايش ال functions تبع

328
00:31:23,700 --> 00:31:29,120
ال CSF؟ أول شي support and protect the CNS against

329
00:31:29,120 --> 00:31:34,420
trauma بيعملوا عملية امتصاص للصدماتTake place of

330
00:31:34,420 --> 00:31:38,620
the lymph بعملوا protection لل CNNS من ال micro

331
00:31:38,620 --> 00:31:44,700
organism the Regulation of the intracranial pressure

332
00:31:46,010 --> 00:31:49,250
لأنه احنا أول شي برجع لرقم اتنين قلنا بيعملوا

333
00:31:49,250 --> 00:31:52,590
عملية protection against microorganism لإنه ال CNS

334
00:31:52,590 --> 00:31:56,810
مافيش في ال CNS the lymph أو the lymph nodes أو the lymphatic

335
00:31:56,810 --> 00:32:01,730
vessels مين بيقوم في الحاجة هذه اللي هو ال CSF زاد

336
00:32:01,730 --> 00:32:06,670
اللي هو the microglial cells the regulation of the

337
00:32:06,670 --> 00:32:10,330
intracranial pressure remove metabolites and

338
00:32:10,330 --> 00:32:13,810
toxics from the central nervous system and

339
00:32:13,810 --> 00:32:18,970
the nourishment function of the CNS بيعملوا عملية تغذية لل

340
00:32:18,970 --> 00:32:23,290
the CNS هنا بزيلوا المواد والفضلات اللي بتخرج من

341
00:32:23,290 --> 00:32:27,310
الميتابوليزم والمواد السامة من ال brain الـ

342
00:32:27,310 --> 00:32:32,430
Characters of the normal CSF the Appearance بيكون

343
00:32:32,430 --> 00:32:35,970
Clear Water Fluid the Isotonic بيكون لون لون الماء ال

344
00:32:35,970 --> 00:32:39,510
the amount حوالي 100 ل 150 ملي لتر ال the replacement

345
00:32:39,510 --> 00:32:45,150
بتغير تلات مرات هذا ال CSF بيحدث the production تقريبا

346
00:32:45,150 --> 00:32:48,590
تلاتة من عشرة لاربع من عشرة ملي لتر بالدقيقة

347
00:32:48,590 --> 00:32:53,770
الواحدة في اليوم بيصنع جسمنا من أربع مية لخمس مائة

348
00:32:53,770 --> 00:32:59,380
ملي لتر the CSF ال pressure بتاعه 100 ل 180 millimeter

349
00:32:59,380 --> 00:33:02,720
of water ال the blood pressure بيكون of mercury هنا

350
00:33:02,720 --> 00:33:06,960
of water ال the rate of the production قلناه the cells بيكونوا

351
00:33:06,960 --> 00:33:10,100
ال cells ال the white blood cells بيكونوا من 0 ل 5 و

352
00:33:10,100 --> 00:33:13,580
بيكونوا كلهم the lymphocytes بيكونوا كلهم the lymphocytes

353
00:33:13,580 --> 00:33:17,440
ولا واحدة neutrophils ال the RBCs كلوات الدم الحمراء

354
00:33:17,440 --> 00:33:19,900
لازم تكون zero مش موجودة كلوات الدم الحمراء

355
00:33:20,390 --> 00:33:25,450
the glucose 60 ميلي جرام لديسلتر و أصحى نقول 70% من

356
00:33:25,450 --> 00:33:27,530
the Ceramic Glucose لأنه ممكن المريض يكون مريض

357
00:33:27,530 --> 00:33:30,770
سكر، سكره عالي أو العكس، سكره محروق يبقى بتتم

358
00:33:30,770 --> 00:33:33,830
المقارنة مع الـ the Ceramic Glucose و الـ the Total

359
00:33:33,830 --> 00:33:39,090
the Protein من 15 ل 50 ميلي جرام لديسلتر، أنا بدي أشرح

360
00:33:39,090 --> 00:33:43,600
بس لو .. لو حدث the tumor هنالو اجت the tumor في ال

361
00:33:43,600 --> 00:33:49,120
the midbrain أو في ال the cerebellum وضغط على ايه؟ على اللي

362
00:33:49,120 --> 00:33:52,220
هو ال the Sylvius aqueduct، the cerebral aqueduct في

363
00:33:52,220 --> 00:33:56,940
الحالة هذه بيحدث عندنا حاجة اسمها the hydrocephalus،

364
00:33:56,940 --> 00:34:00,450
بيصير انتفاخ في البطين في الحالة هاد راح يصير

365
00:34:00,450 --> 00:34:04,130
the dilatation في ال third ventricle و ال both

366
00:34:04,130 --> 00:34:09,150
ventricles لكن لو حدث the exclusion في one monroe يصير

367
00:34:09,150 --> 00:34:12,910
the dilatation في one lateral ventricle two monroe في

368
00:34:12,910 --> 00:34:15,770
ال two lateral ventricles و هكذا

369
00:34:18,850 --> 00:34:21,890
بهيك بنكون إن شاء الله وصلنا لنهاية المحاضرة بتاعة

370
00:34:21,890 --> 00:34:25,070
ال mini G و هي ال the ventricular system of the brain

371
00:34:25,070 --> 00:34:27,870
and the cerebrospinal fluid circulation
