Anatomy of the Spine

The spinal column is the body’s main support structure. It has thirty-three bones, called vertebrae, which are divided into five regions: cervical, thoracic, lumbar, sacral and coccygeal. It surrounds and protects your spinal cord much like a conduit around an electrical cord. The spinal cord is a bundle of nerves that run from your brain through your spinal column and branch out to the rest of the body.  The spinal cord connects the brain to the rest of the body.
