Thoracic Cord

The thoracic cord is the upper and middle portion of the back. It is compromised of the 12 vertebrae. T-1 through T-5 is responsible mostly for the control of the ribcage, diaphragm, and muscle that aid in breathing, while T-6 through T-12 play a role in balance and posture.

An injury in this region of the spinal cord will most likely result in paraplegia.
