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.
A: The phrenic nerve controls the diaphragm, a muscle located under the lungs. The phrenic nerve signals the diaphragm muscle to contract when a person is about to inhale. When the diaphragm muscle contracts, it moves downward, leaving room for the lungs to expand.
