Injury at this level of the spinal cord might injure the phrenic nerve. This nerve supplies the diaphragm, which permits inspiration and expiration. If this nerve is damaged, the impulses no longer reach the diaphragm and the diaphragm stops contracting.
The thoracic diaphragm is essentially a large muscle. Like all muscles, it has tendons that attach to the muscles and secure it. The diaphragm is attached to the inside of the ribs, to the back of the breastbone and the spine. The muscle fibers then meet in the middle of the diaphragm at the central tendon.
