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.
Carotid arteries are located on each side of the neck, just below the jaw line. They supply blood to the anterior (front) brain where sensory and motor function as well as speech, vision, personality and thinking reside. Two smaller arteries -- the vertebral arteries -- supply blood to the back of the brain, the cerebellum and brainstem.
