The vertebral artery is a major artery of the neck that passes through the cervical vertebrae. There are two vertebral arteries, one on each side, and each branches off from the subclavian artery. They merge to form the single basilar artery at the base of the brain.
These arteries supply blood, oxygen, and nutrients to vital brain structures, such as your brainstem, occipital lobes, and cerebellum. A condition called atherosclerosis can reduce or stop blood flow through the vertebrobasilar system. Atherosclerosis is a hardening and blockage of the arteries.
