Knowledge is Spinal Health: Getting to Know the Spinal Motion Segment
Good spinal health begins with having all the facts in hand: have you heard of spinal motion segments?
Spinal motion segments have two main functions: facilitating movement of the upper body and stabilizing the spine in order to prevent injury from excessive movement. They consist of: 2 vertebrae, 2 facet joints, 1 intervertebral disc and a whole network of supportive soft tissue. The vertebrae, intervertebral disc and facet joints form the articular triad; these are the structures that allow for minute articulation between vertebrae and thus, when all the spinal motion segments are put together, for the overall articulation of the spine and upper body.
