The spine is an important structure of the human body. It consists of 24 vertebrae (7 cervical, 12 thoracic and 5 lumbar), one sacrum and one coccyx connected by ligaments, joints and intervertebral discs. The spine supports the skull, the hip bones, the ribs, and serves as the posterior wall of the thoracic, abdominal, and pelvic cavities. The spinal canal, which is longitudinally shaped inside the spine, houses the spinal cord. The spine has two main functions: stability and mobility, which are mediated through a complex neuromusculoskeletal system.
