The spinal cavity, also known as the vertebral canal or spinal canal, is a hollow space within the vertebral column that houses and protects the spinal cord. It is formed by the stacked vertebrae and the intervertebral discs between them. The main function of the spinal cavity is to provide a protective and supportive environment for the spinal cord, which is a crucial part of the central nervous system. It acts as a physical barrier, shielding the delicate spinal cord from external pressure, trauma, and other potential injuries. The spinal cavity also helps to maintain the stability and alignment of the vertebral column.
