Additional Information

The spine provides support and stability to the body, allowing for a wide range of movements and flexibility. It is also protected by muscles, ligaments, and the surrounding vertebrae, which work together to provide strength and support. In human anatomy, the spine is divided into the cervical, thoracic, lumbar, sacral, and coccyx regions, each with distinct characteristics and functions.

Furthermore, the spine is susceptible to various conditions and disorders, such as herniated discs, spinal fractures, and degenerative disc disease, which can cause pain and discomfort. Regular exercise, stretching, and proper posture can help maintain a healthy spine and reduce the risk of such issues.
