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 diaphragm is a sheet of muscle under the lungs that plays a vital role in the breathing process, explains InnerBody. The diaphragm is a dome-shaped muscle sheet that separates the thoracic and abdominal cavity. The lungs are enclosed in the thoracic cavity, resting directly above the diaphragm.
