Question

Which of the following is not an artery of the base of the brain?
A)Subclavian artery
B)Basilar artery
C)Posterior communicating artery
D)Vertebral artery
E)All of these are arteries of the base of the brain.

Accepted Answer

The subclavian artery is not considered an artery of the base of the brain as it originates in the chest rather than the head/neck region. The other options (basilar artery, posterior communicating artery, and vertebral artery) are all arteries that contribute to the blood supply of the base of the brain.
