Question

multiple choice question
the right and left vertebral arteries merge to form the ______ artery.
o jugular
o posterior communicating
o basilar
o common carotid

Explanation:

In human anatomy, the right and left vertebral arteries merge to form the basilar artery. This is a key part of the cerebral arterial circle. The jugular is a vein, not an artery formed by vertebral - artery merger. The posterior communicating artery is part of the circle of Willis but not formed by vertebral - artery merger. The common carotid artery has a different origin and function.

Answer:

C. basilar
