The vertebral column, also known as the backbone or spine, is part of the axial skeleton. The vertebral column is the defining characteristic of a vertebrate, in which the notochord a flexible rod of uniform composition found in all chordates has been replaced by a segmented series of bones—vertebrae separated by intervertebral discs.[1] The vertebral column houses the spinal canal, a cavity that encloses and protects the spinal cord.
