What stabilizes the spine?

Ligaments, tendons and muscles are like small ropes that help stabilize and balance the spinal column. Spinal ligaments connect bone to bone, help hold vertebrae in place, and limit movement to help prevent injury. (Fig. 1) The spine's tendons connect bone to muscle and serve as anchors to aid muscles when they contract during joint movement.

Each spinal structure works together as a team to balance the spine at rest and during movement. The spinal muscles are important. Building and preserving spinal strength is central to staying healthy and active at any age. When there is an injury our nervous system inhibits the function of some muscles.
