Flashcards in circulacion cerebral Deck (15):
1

from which pair of arteries fo the arteries supplying the brain arise from?

- Vertebrals: arise from the subclavian in the neck, ascend through the transverse foramina of the cervical vertebrae, and enter the foramen magnum of the skull to supply the posterior portion of the brain.
- Internal carotids: arise from the common carotid in the neck, ascend in the neck to enter the carotid canal, and traverse the foramen lacerum to terminate as the middle and anterior cerebral arteries, which anastomose with the circle of Willis around the optic chiasm, hypophysis, and basal hypothalamus

2

course and structures supplied by the vertebral artery

from subclavian artery
supplies cerebellum

3

course and structures supplied by the posterior inferior cerebellar artery

from vertebral artery
goes to posteroinferior cerebellum

4

course and structures supplied by the basilar artery

from both vertebrals
goes to brainstem, cerebellum, cerebrum

5

course and structures supplied by the anterior inferior cerebellar artery

from basilar
supplies inferior cerebellum

6

course and structures supplied by the superior cerebellar artery

from basilar
supplies superior cerebellum

7

course and structures supplied by the posterior cerebral artery

from basilar
supplies inferior cerebrum, occipial lobe

8

course and structures supplied by the posterior communicating artery

it's part of the cerebral arterial circle of Willis

9

course and structures supplied by the internal carotid artery

from common carotid
supplies cerebral lobes and eye

10

course and structures supplied by the middle cerebral artery

from internal carotid
goes to lateral aspect of cerebral hemispheres

11

course and structures supplied by the anterior communicating artery

it's part of the cerebral arterial circle of Willis

12

course and structures supplied by the anterior cerebral artery

from internal carotidgoes to cerebral hemispheres (except occipital lobe)

13

what happens when there is an occlusion of the anterior cerebral artery

it can disrupt sensory and motor functions on the contralateral lower extremity

14

what happens when there is an occlusion of the middle cerebral artery

it can disrupt sensory and motor functions on the contralateral upper extremity or, if the internal capsule is affected, the entire contralateral body

15

what happens when there is an occlusion of the posterior cerebral artery

it can disrupt visual functions from the contralateral visual field
