When It’s Healthy

Your spine is made up of more than 30 bones, called vertebrae, and consists of three main sections: cervical, thoracic, and lumbar. Your vertebrae are held together by ligaments, muscles, and “shock absorbing” discs. In a healthy spine, there is space between the spinal nerves and the borders of the spinal canal. This space allows the spinal sac of nerves and nerves leaving the spine to exit the spinal canal freely and extend to different parts of the body.
