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.
As the only source of motor innervation to the diaphragm, this nerve has an important role in breathing. In this article, we shall look at the anatomy of the phrenic nerve â its anatomical course, motor and sensory functions. Nerve roots: Anterior rami of C3, C4 and C5. Motor functions: Innervates the diaphragm.
