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 phrenic nerve innervates the diaphragm which is our main breathing muscle. It is a broad flat sheet that encircles our lower ribcage and separates our thoracic from our ab â¦ dominal cavities. The phrenic nerve arises from the C3-C5 level of our vertebrae.he phrenic nerve innervates the diaphragm which is our main breathing muscle.
