The spinal cord is comprised of neural pathways. In order for a message to go from the brain to the body, the message is passed form neuron to neuron. The spinal chord is the main conduit between the brain and the body.

There are four segments of the spinal chord. Going from top to bottom there are the cervical, thoracic, lumbar and sacral segments. Injury to a certain segment of the cord will effect parts of the body below the point of injury.
