The spinal cord is surrounded by the vertebral column, which consists of a number of discrete bones called the vertebrae. Each vertebra consists of a cylindrical bone anteriorly called the body, two lateral processes called transverse processes, and a dorsal process called the spinal process. The transverse processes are connected to the vertebral body by the pedicles and to the spinous process by the laminae. The hollow in the ring is formed by the posterior vertebral body, pedicles, laminae, medial transverse process and anterior spinous process forms part of the spinal canal. The successive vertebrae articulate with one another intervened by discs and facet joints (Figure 38-1).
