Blood vessels · Latin: Arteria vertebralis

The vertebral arteries are major arteries of the neck.

Typically, the vertebral arteries originate from the subclavian arteries.

Each vessel courses superiorly along each side of the neck, merging within the skull to form the single, midline basilar artery.

As the supplying component of the vertebrobasilar vascular system, the vertebral arteries supply blood to the upper spinal cord, brainstem, cerebellum, and posterior part of brain.
