phrenic nerve Provides motor innervation to the diaphragm; The main muscles of breathing. Since the phrenic nerves are bilateral, each nerve supplies the ipsilateral side of the diaphragm (the hemidiaphragm on the same side as itself).

Why is the diaphragm innervated by the phrenic nerve?

nerve is Important for breathing as it provides exclusive motor control of the diaphragm, the main muscle of breathing. In humans, the left and right phrenic nerves are primarily supplied by the C4 spinal nerve, but there are also contributions from the C3 and C5 spinal nerves.

How does the phrenic nerve control the diaphragm?
