What is "vertebral artery"?

The vertebral artery is a major blood vessel that plays a crucial role in supplying oxygenated blood to the brain and spinal cord. It arises from the subclavian artery in the chest and ascends through the vertebrae of the neck, eventually entering the skull to join with its counterpart and form the basilar artery. The vertebral artery supplies vital nutrients and oxygen to the posterior regions of the brain, contributing to various functions such as balance, coordination, and sensory processing. It is a critical component of the circulatory system, ensuring the proper functioning of the central nervous system.
