What are the phrenic nerves?

The phrenic nerve originates from the anterior rami of the C3 through C5 nerve roots and consists of motor, sensory, and sympathetic nerve fibers. It provides complete motor innervation to the diaphragm and sensation to the central tendon aspect of the diaphragm.

What happens if cranial nerve 5 is damaged?

A trigeminal nerve injury may affect a small area, like part of your gum, or a large area, like one side of your face. The injury can cause problems with chewing and speaking.
