What is the function of the spine?

The spine is an important, central part of the musculoskeletal system. It consists of 33 small bones – vertebrae. They are all connected to each other by joints and ligaments. These joints provide mobility of the spine in all planes. The spine is essential for ensuring walking and maintaining the correct position of the body in space. Its physiological curves are needed precisely for walking in an upright position. There is a bony canal inside the spine. Inside it is the spinal cord – an organ of the nervous system. The spine protects the spinal cord from external influences.
