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
circulationThe 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 CSFis 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 تمنا production ل ال

12
00:01:03,140 --> 00:01:09,410
CSFEach part of the central nervous system contain

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 third ventricle في

16
00:01:23,250 --> 00:01:26,510
الcerebellum و المدلة 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 aqueductالـ 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 interconnection 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 ventriclethird

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 interconnection

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 ofthird 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 او cerebral

37
00:03:26,520 --> 00:03:33,270
aqueduct اسمها silvius aqueductأو 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
ب 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 او

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 فى

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

61
00:06:51,760 --> 00:06:59,320
هنا فى right interventricular foramen of monroe

62
00:06:59,320 --> 00:07:05,210
يعني احنا رسلناleft 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 Monroe كم Monroe فينا؟

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

68
00:07:28,050 --> 00:07:32,150
Monroe و في right foramen of Monroe 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 Monroe 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 loop، posterior horn أو occipital horn

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

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

79
00:08:17,690 --> 00:08:21,550
يزعل؟ ال parietal loop مايزعلش ال parietal loop 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 loopو

82
00:08:30,990 --> 00:08:36,530
في شي اسمه trigon او atrium دي لاتيشن 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 hornوهنا

87
00:09:00,210 --> 00:09:05,570
ايش ال body او ال central part body او 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 loop في

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

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

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

93
00:09:28,940 --> 00:09:34,000
انتيريور هارن بوستيريور هارن و تحت في ال temporal

94
00:09:34,000 --> 00:09:40,630
loop في inferior horn يعني frontal hornأكسبتال

95
00:09:40,630 --> 00:09:45,310
هورن كيمبورال هورن أو اسم ثاني انتريور هورن

96
00:09:45,310 --> 00:09:50,550
بوستيريور هورن انفريور هورن طب و المكان تلاقي

97
00:09:50,550 --> 00:09:54,790
الانفريور هورن مع ال بوستيريور هورن هذا المكان

98
00:09:54,790 --> 00:10:01,470
بنسميه تريجون بنسميه تريجون او أتريوم of lateral

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

100
00:10:08,870 --> 00:10:15,950
لاحظوا هنا على سجن teleview 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
بنسمي atrium او trigonهو 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 bodyمكان 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 فرم هنا واحد اتنينواحد 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
Monroe Interventricular Foramen of Monroe هذا

117
00:11:41,650 --> 00:11:47,320
واضح على ال axial cutهذا anterior horn وهذا

118
00:11:47,320 --> 00:11:53,100
posterior horn أو هذا posterior horn وهذا تراجون

119
00:11:53,100 --> 00:12:05,980
او أتريام تجي هنا تراجون او أتريام ننتقل

120
00:12:05,980 --> 00:12:15,020
الآن لثير ذنتركل ثير ذنتركل عبارة عن cavityهو

121
00:12:15,020 --> 00:12:19,600
كفتيه of diencephalon it is 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 الهيبو ثلامس بين ال right و ال leftفي adhesion

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

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 او

129
00:12:55,690 --> 00:12:57,810
كمان صح frozen cephalon

130
00:13:00,320 --> 00:13:07,440
هنا عندي ال axial cut هذا هو ال third ventric 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 شي اسمهinterthalamic adhesion connections

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

135
00:13:30,200 --> 00:13:34,340
connection between left and right ثلمائي 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 ل communications of third

138
00:13:44,240 --> 00:13:48,000
ventricle اول communication انا 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 a both

142
00:14:06,570 --> 00:14:13,490
lateral ventricleOkay 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؟ او عن طريق

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

146
00:14:29,270 --> 00:14:34,070
Monroe عندي؟ left and right Monroe 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 communicate 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 enter او بنسميه cerebral .. cerebral

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

155
00:15:25,180 --> 00:15:29,400
silvius aqueduct او 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
communicates

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 Monroe two Monroe

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 withfourth ventricle عن طريق ايه؟

164
00:16:10,380 --> 00:16:15,200
sylvius او 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 منروفورامين 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؟

171
00:17:08,720 --> 00:17:13,100
من رو فورامن 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 من رو ارتبطوا مع ال third

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

176
00:17:29,800 --> 00:17:34,710
aqueductمع 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
Monroe and right and left Monroe 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
الان 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 hind brainو ممكن اقول it

189
00:18:50,070 --> 00:18:55,770
is cavity of rhombocephalon 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 blankata يعني بيحدوا من الخلف

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

193
00:19:12,990 --> 00:19:18,170
medulla او open medullaطيب بكلام ثاني لو بدى نصيغه

194
00:19:18,170 --> 00:19:26,490
وين موجود ال fourth ventricle located between the

195
00:19:26,490 --> 00:19:34,630
dorsal cervix of pons and open medulla and

196
00:19:35,750 --> 00:19:40,130
ventral service of cerebellum يبقى ان هو ال cavity

197
00:19:40,130 --> 00:19:46,190
هذا محصور ما بين ال ventral cavity of cerebellum

198
00:19:46,190 --> 00:19:51,970
من الخلف و ال dorsal service بتاع ال palms و ال

199
00:19:51,970 --> 00:19:59,390
upper medulla او open medulla من الأمام تمام ال

200
00:19:59,390 --> 00:20:05,590
angles الموجودة في ال fourth ventricleأول شيء فيه

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 silvius aqueduct

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

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 medullaطيب و ال lateral angle

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

207
00:20:41,470 --> 00:20:45,530
logica right logica فرمن و left logica فرمن 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
angle superior angle مين فاتح فيه فاتح اللي هو

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

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

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

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

214
00:21:30,080 --> 00:21:34,500
Spinal Canal 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
Spinal Cord يبقى عندي Inferior Angle فاتح فيه اللي

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

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

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

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

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

222
00:22:10,680 --> 00:22:15,120
بالطريقة هذه انا شرحتلكم ال angles of 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 اتكلمتعن communication بين ال fourth

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

227
00:22:40,720 --> 00:22:44,140
او 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 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 formina

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

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 فرمان

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

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

238
00:23:50,970 --> 00:23:54,970
صاروا اربعة صاروا كام فرمان او communication اربعة

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

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

241
00:24:04,690 --> 00:24:10,390
ventricle 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 cordو

243
00:24:16,800 --> 00:24:21,160
ثلاثة فرامنة .. يعني ثلاثة فرامنة تولوشكة فرامنة

244
00:24:21,160 --> 00:24:24,340
بيكون اللاترال أو وان ماجيندي فرامن بيكون

245
00:24:24,340 --> 00:24:30,450
بوستيريور هدول بيصرفوا ال CSFمن ال fourth

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

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

248
00:24:40,210 --> 00:24:45,970
cistern و احنا اتفجنا ان ال cistern هي عبارة عن

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

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

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

252
00:25:02,160 --> 00:25:05,680
هنا واضح هى 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 اول

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
cerebral aqueduct او sylvius aqueduct هى اول واحد

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

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

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

260
00:25:47,740 --> 00:25:53,070
بيكون فرع من Magendieالسيلفياس اكويداكت او

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

262
00:25:56,470 --> 00:26:03,670
fourth ventricle 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
central spinal canal بتاعة ال spinal cordفورا من

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

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

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

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

269
00:26:32,310 --> 00:26:39,700
ال ventricular system هاي واضح syllabus aqueductأو

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

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

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

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

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

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

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

277
00:27:18,340 --> 00:27:23,220
ابن دايمة ال cells موجودة في الكرويذيا لبليكساس of

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

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

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

281
00:27:40,610 --> 00:27:45,630
بتاعة الارتريز 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 circulation of CSF سيبونا من ال slide هذا

284
00:27:53,910 --> 00:27:58,410
نتبع مع بعض على slide هان او بتقول على ال slide

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

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

287
00:28:07,190 --> 00:28:11,910
بعبر عن طريق الـ interventricular forum من أومنروه

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
لcerebral 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 central spinal canal ل 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 فورامنا و لوشكا فورامنا right and left

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

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

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

302
00:29:30,710 --> 00:29:35,570
انا 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 نشوفهThe CSF in each

305
00:29:46,850 --> 00:29:49,490
lateral ventricle بمورف الـ 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
Aqueduct of Silvius أو Silvius Aqueduct بمورفيه

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 Central Spinal Canalوالجزء الأكبر بيروح

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

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

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

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

314
00:30:23,590 --> 00:30:28,740
spaceمنهم بيروح للـ subarachnoid space بتاعة ال

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

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

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

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

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

320
00:30:51,350 --> 00:30:56,050
بتاعة ال CSF للي ديورال venous sinuses و من لي

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

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

323
00:31:02,430 --> 00:31:10,100
stream لاللي هو right atrium of the heartهذا واضح

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

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

326
00:31:16,300 --> 00:31:19,660
arachnoid space و بيسلموه لديور ال venous sinuses

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

328
00:31:23,700 --> 00:31:29,120
ال CSF؟ اول 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 Regulation of the intracranial pressure

332
00:31:46,010 --> 00:31:49,250
لأنه احنا اول 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 lymph أو lymph nodes او 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 microglial cellsregulation 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
nourishment function of CNS بيعملوا عملية تغذية لل

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

341
00:32:23,290 --> 00:32:27,310
الميتاباليزم والمواد السامة من ال brainالـ

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

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

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

345
00:32:39,510 --> 00:32:45,150
بتغير تلاث مرات هذا ال CSF بيحدث 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 CSFال pressure بتاعه 100 ل 180 millimeter

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

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

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

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

353
00:33:13,580 --> 00:33:17,440
ولا واحدة نيترو فيلز ال 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
الجلوكوز 60 ميلي جرام لديسلتر و أصحى نقول 70% من

356
00:33:25,450 --> 00:33:27,530
الـ 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 Ceramic Glucose و الـ Total

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

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

361
00:33:43,600 --> 00:33:49,120
midbrain او في الcerebellum وضغط على ايه؟ على اللي

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

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

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

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

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

367
00:34:09,150 --> 00:34:12,910
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 ان شاء الله وصلنا لنهاية المحاضرة بتاعة

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

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