Function of the spine

The spine is an ingenious structure of the human body that enables many different functions. First of all, it keeps the body upright and is therefore not called the “backbone” for nothing. A complex interplay of bony structures, ligaments and muscles makes it possible to stabilize the trunk, neck and head.

In this respect, the upright gait distinguishes humans from other vertebrates. Towards the top, the spine supports the skull and at the same time allows the head to move freely to all sides. Furthermore, the spine is connected to the ribs by many small joints and is connected to the shoulder girdle.

The sacrum as the lower end of the spine contributes to the formation of the pelvis by forming the so-called pelvic ring with other bones. Another important function of the spine is that it provides bony protection around the sensitive spinal cord.The spinal cord passes through a bony opening in the skull bone and then runs through the spinal canal or spinal canal (Canalis vertebralis), which is formed by the individual vertebral bodies lying one above the other. The spinal canal has an opening on each side, the intervertebral hole (Foramen intervertebrale). This is always formed by two vertebrae lying one above the other and is the exit point for the so-called spinal nerves (spinal cord nerves).
