The vertebrae and the soft tissues come together and constitute the spine. As the vertebra structure changes according to the region of the spine, the all vertebrae consists an anterior part namely vertebral body, which is durable for compressive and tensile loads and a posterior part (neural arch) consisting and protecting the spinal cord meanwhile allows movement of the spine. Intervertebral discs, which absorb the load applied to the vertebrae and regularize the load distribution as having a viscoelastic structure, are positioned between two adjacent vertebrae. The whole construction of the spine is tied together by ligaments and muscles.
