Your spine, also referred to as the backbone, is made up of 24 vertebrae that form a column. This column spans your entire torso, from the base of your skull, all the way down to your pelvis. Discs made of a gel-like substance contained in fibrous tissue are found in between each vertebra. These discs absorb shock and allow for motion along the spine.
Through the centre of the column is the spinal cord, encased by the vertebrae for support and protection. The spinal cord is connected directly to the brain by way of the brain stem. Nerves branch off from the spinal cord to connect all areas of the body to the brain.
