Between the vertebral bodies are the intervertebral discs, providing cushioning and shock absorption. The vertebral bodies also provide (in combination with other parts of the vertebra) the boundaries for the spaces through which the spinal cord travels, as well as branching nerves that exit the spine on their way to all parts of the body.
Vertebral artery. The vertebral arteries are major arteries of the neck. They arise as branches from the subclavian arteries or can arise from aortic arch and merge to form the single midline basilar artery. As the vertebrobasilar system, they supply blood to the upper spinal cord, brainstem, cerebellum, and posterior part of brain.
