Definition: A motion segment consists of two adjacent vertebrae, including the intervertebral disk between them, and the ligaments that bind them together. Nerves branching off from the spinal cord exit out of each spinal motion segment to receive and deliver messages for the body. If the vertebrae comprising the motion segment are aligned properly, the nerves can do their job in an uninterrupted fashion. In cases of subluxation, however, the transmission ability of the nerves become impaired. Chiropractors address subluxation with manipulation and adjustment.
