Description. The vertebral artery is a major artery in the neck. It branches from the subclavian artery, where it arises from the posterosuperior portion of the subclavian artery.

The vertebral artery usually originates from the posterior surface of the subclavian artery as the first branch of the subclavian artery, but it can also originate from the aortic arch and common carotid artery.
