The spinal column, also known as the vertebral column, is a flexible structure made up of individual bones called vertebrae. It extends from the base of the skull to the lower back and is divided into several regions: cervical, thoracic, lumbar, sacral, and coccygeal. The spinal column protects the spinal cord, which is a vital part of the nervous system that transmits signals between the brain and the rest of the body. In addition to providing support and stability, the spinal column allows for a range of movements, such as bending and twisting. It also serves as an attachment point for muscles and ligaments, contributing to overall posture and balance. Proper care of the spinal column is essential for maintaining mobility and preventing injuries.
