The human spine from the left side. The spine supports the head, holds the body upright, and protectively encircles the spinal cord which passes through its central cavity. The spine consists of 33 vertebrae, articulated by intervertebral discs which allow flexibility and movement. Damage to the intervertebral discs that lie between the vertebrae (such as a 'slipped disc or disc protrusion) is a common condition that can resolve spontaneously, but may require surgery such as discectomy.
