The Merger of These Two Arteries Forms the Basilar Artery

Question

The merger of these two arteries forms the basilar artery.
A) Internal carotid arteries
B) Subclavian arteries
C) Vertebral arteries
D) Brachiocephalic arteries

Accepted Answer

The vertebral arteries merge together to form the basilar artery, which supplies blood to the brainstem and cerebellum. The internal carotid arteries and subclavian arteries are separate from the vertebral arteries and do not merge to form the basilar artery. The brachiocephalic arteries are located in the chest and supply blood to the arms and head, not to the brainstem or cerebellum.
