Question

Two pairs of arteries supply the brain. They are .
A) vertebrals and internal carotids
B) internal and external carotids
C) internal carotids and brachiocephalics
D) common carotids and vertebrals

Accepted Answer

The vertebral arteries merge to form the basilar artery, which along with the internal carotid arteries, contributes to the Circle of Willis, a ring of arteries that provides multiple pathways for blood to supply the brain.
