Corpus: Phrenic plexus

The phrenic plexus is a nerve plexus that accompanies the inferior phrenic artery to the diaphragm.

The phrenic plexus receives its fibres from the upper section of the ganglia coeliaca and from the phrenic nerve. On the right side of the body there is a small ganglion, the phrenic ganglion, at the junction of the phrenic plexus and the phrenic nerve.

The fibres of the phrenic plexus run with the artery into the diaphragm. Smaller parts supply the adrenal glands and run to the inferior vena cava.
