Brain vasculature

Question 1

internal carotid artery

Answer 1

Branch of common and goes through carotid canal. feeds the anterior and middle cerebral arteries

Question 2

anterior cerebral artery

Answer 2

supplies medial portions of the frontal and parietal lobes

branches from internal carotid

Question 3

middle cerebral artery

Answer 3

supplies lateral portions of the frontal parietal, and temoral lobes. branches from internal carotid

Question 4

anterior communicating artery

Answer 4

communicating branch between the two anterior cerebral arteries

Question 5

anterior choroidal artery

Answer 5

supplies the choroid plexus beginning in the temmporal lobe

Question 6

posterior communicating artery

Answer 6

communicating branch between the internal carotid and the posterior cerebral arteries. supplies posterior thalamus

Question 7

Vertebral arteries

Answer 7

originate from subclavian. pass through cervical transverse foramen and enter through foramen magnum

Question 8

posterior inferior cerebellar artery

Answer 8

branch of the vertebral artery supplies the lateral brain stem and the posterior inferior cerebellum

Question 9

anterior spinal artery

Answer 9

originates from the vertebral artery and supplies the ventral and intermediate grey matter of the spinal cord

Question 10

basilar artery

Answer 10

the two vertebral arteries join to form this at the junction of the pons and medulla. becomes posterior cerebral arteries

Question 11
