Flashcards in CNS vasc Deck (45):
1

vertebral arteries (R and L)

ascend through the transverse foramina of the cervical vertebra and enter the cranial cavity via the foramen magnum.

2

internal carotid arteries

ascend through the neck to the base of the skull and enter the cranial cavity through the carotid canal.

3

The vertebral arteries contribute to the -------

circulation

The vertebral arteries contribute to the posterior circulation

4

Vertebral arteries

, ascend through the transverse foramina of the cervical vertebra and enter the cranial cavity via the foramen magnum.

5

pontomedullary junction,

the right and left vertebral arteries unite to form the basilar artery.

6

The anterior and posterior spinal arteries

arise from the vertebral arteries

7

supply the spinal cord

anterior and posterior spinal arteries

8

travel midline spinal cord (

Anterior Spinal Artery

9

travel just posterior to the dorsal horn of the spinal cord (bilateral)

Posterior Spinal Arteries

10

spinal arteries braches from the vertebral artery provide

sufficient blood supply to the upper cervical spinal cord levels only.

11

one anterior and two posterior spinal arteries extend -----to supply the spinal cord

one anterior and two posterior spinal arteries extend caudally to supply the spinal cord

12

radicular arteries.

reinforce anterior and posterior spinal arteries

13

radicular arteries

branches off of the posterior intercostal arteries.

14

radicular artery at ~T12 spinal cord level

called the great radicular artery

may provide the entire arterial supply for the lumbosacral spinal cord.

15

vertigo and ipsilateral deafness

occlusion of  internal auditory or labyrinthine artery

16

basilar artery terminates by bifurcating

into the two posterior cerebral arteries

17

which of the following isnt a branch of the basilar art

basilar artery

22

rostral pontine levels

basilar artery and superior cerebellar artery

23

Most of the midbrain is supplied by the ------ ----- ---- and their branches

Most of the midbrain is supplied by the posterior cerebral arteries and their branches

24

Blood supply to the most dorsal aspect of the midbrain arises from the ------- ------- -------

Blood supply to the most dorsal aspect of the midbrain arises from the superior cerebellar artery.

25

Supplies the occipital lobe and medial and inferior surface of the temporal lobe

The “Circle of Willis” connects the ----- and -----

arterial cerebral circulation

The “Circle of Willis” connects the anterior and posterior arterial cerebral circulation

©Both ICAs terminate by giving rise to

a middle cerebral artery (MCA) and anterior cerebral artery (ACA).
