How Is the Diaphragm Innervated

The diaphragm is primarily innervated by the phrenic nerve which is formed from the cervical nerves C3, C4 and C5.

What is the innervation of the diaphragm?

The phrenic nerve is a bilateral, mixed nerve that originates from the cervical nerves in the neck and descends through the thorax to innervate the diaphragm. It is the only source of motor innervation to the diaphragm and therefore plays a crucial role in breathing.

Is the diaphragm innervated by the autonomic nervous system?

The human phrenic nerve serves as a morphological conduit for autonomic nerves and innervates the caval body of the diaphragm.
