Veins/Vessels

Question 1

The veins of the spinal cord collectively drain into

Answer 1

the internal venous plexus of Batson, which is located in the epidural space. This plexus empties into intervertebral veins and segmental veins, sequentially.

Question 2

Superficial Venous Drainage of the Cerebral Hemispheres

Answer 2

1. The superficial middle cerebral vein: the most prominent of the superficial veins.
2. located in the lateral fissure.
3. drains most of the cortex of the lateral aspect of the cerebral hemispheres.
4. empties into the cavernous sinus, the superior saggital sinus via the superior anastomotic veins, and the transverse sinuses via inferior anastomotic veins

Question 3

Deep Venous Drainage of the Cerebral Hemispheres

Answer 3

Internal cerebral vein

courses next to the parahippocampal gyrus.

receives the thalamostriate and anterior septal veins, and drains into the great vein of Galen.

Thalamostriate (Terminal) vein is located next to the medial aspect of the caudate nucleus in the floor of the lateral ventricle. The stria terminalis is also beside the vein. It drains the corpus striatum, and empties into the internal cerebral vein.

Anterior septal vein is located next to the interventricular foramen. It drains the septal area of the limbic lobe, and empties into the internal cerebral vein.

Question 4

courses next to the parahippocampal gyrus. It receives the thalamostriate and anterior septal veins, and drains into the great vein of Galen.

Answer 4

Internal cerebral vein

it courses next to the parahippocampal gyrus.

It receives the thalamostriate, anterior septal veins, and drains into the great vein of Galen.

Question 5

is located next to the medial aspect of the caudate nucleus in the floor of the lateral ventricle. The stria terminalis is also beside the vein. It drains the corpus striatum, and empties into the internal cerebral vein.

Answer 5

Thalamostriate (Terminal) vein

located next to the medial aspect of the caudate nucleus in the floor of the lateral ventricle. The stria terminalis is also beside the vein. It drains the corpus striatum, and empties into the internal cerebral vein.

Question 6

located next to the interventricular foramen. It drains the septal area of the limbic lobe, and empties into the internal cerebral vein.

Answer 6

Anterior septal vein

Question 7

adjacent to the cerebral peduncle.

Answer 7

Basal vein of Rosenthal

1. adjacent to the cerebral peduncle.
2. basal vein receives middle deep cerebral and anterior cerebral veins
3. drains into the grain vein of Galan

Question 8

located adjacent to the insula that it drains.

Answer 8

1. Middle deep cerebral vein is located adjacent to the insula that it drains. It empties into the basal vein of Rosenthal.

Question 9

located at the base of the frontal lobe, which it drains.

Answer 9

Anterior cerebral vein is located at the base of the frontal lobe, which it drains. It empties into the basal vein of Rosenthal.

Question 10

courses adjacent to the posterior portion of the corpus callosum.

Answer 10

Great vein of Galen courses adjacent to the posterior portion of the corpus callosum.

It receives the internal cerebral and basal veins, and drains into the straight sinus.

Question 11

receives the internal cerebral and basal veins, and drains into the straight sinus.

Answer 11

Great vein of Galen

Question 12

1. obstruction of this vein is usually fatal.
2. It may also become dilated and form a ___S____
3. S may compress ________

Answer 12

1. Great vein of Galen
2. venous varix.
3. the pineal body and posterior commissure.

Question 13

Dural venous sinuses

Answer 13

1. The superior sagittal sinus- drains most of the cerebral cortex, usually drains into the right transverse sinus
2. The straight sinus: formed at falx/tentorium intersection.: Great Vein of Galan empties into it
3. The confluens drains superior sagittal, straight and occipital sinuses.

Question 14

xtends from the crista galli to the confluens in the area of the attached border of the falx. It drains most of the cerebral cortex, and in most cases, it empties into the right transverse sinus.

Answer 14

The superior sagittal sinus is a large venous sinus that extends from the crista galli to the confluens in the area of the attached border of the falx. It drains most of the cerebral cortex, and in most cases, it empties into the right transverse sinus. Venous lacunae are adjacent to the sinus and drain into the sinus along with the superior cerebral veins.

Question 15

formed at the intersection of the falx and the tentorium. The great cerebral vein of Galen drains vital deep structures of the cerebrum, and empties into the straight sinus.

Answer 15

The straight sinus is formed at the intersection of the falx and the tentorium. The great cerebral vein of Galen drains vital deep structures of the cerebrum, and empties into the straight sinus. Occlusion of either of these vessels is usually fatal. In most cases the straight sinus drains into the left transverse sinus.

The confluens receives the superior sagittal, straight and occipital sinuses. It is usually asymmetrical in its drainage pattern.

.

Question 16

receives the superior sagittal, straight and occipital sinuses. It is usually asymmetrical in its drainage pattern.

Answer 16

The confluens receives the superior sagittal, straight and occipital sinuses. It is usually asymmetrical in its drainage pattern.

Question 17

1. Thrombosis of the posterior portion of the superior venous sinus or right transverse venous sinus
2. Thrombosis of the posterior portion of the straight venous sinus or left transverse venous sinus

Answer 17

Thrombosis of the posterior portion of the superior venous sinus or right transverse venous sinus results in cortical ischemia and/or necrosis.

Thrombosis of the posterior portion of the straight venous sinus or left transverse venous sinus results in ischemia and/or necrosis of structures in the deep cerebrum. This is usually fatal.

Question 19

It drains most of the cerebral cortex

Answer 19

superior sagittal sinus is a large venous sinus that extends from the crista galli to the confluens in the area of the attached border of the falx. It drains most of the cerebral cortex, and in most cases, it empties into the right transverse sinus. Venous lacunae are adjacent to the sinus and drain into the sinus along with the superior cerebral veins.
