The phrenic plexus (plural: plexuses) is an autonomic nerve plexus and ganglia in the upper abdomen. It is a lateral epiarterial extension of the celiac plexus.
Summary
location: the bilateral ganglia and plexuses lie along the inferior phrenic arteries
origin: preganglionic sympathetic fibers via the greater and lesser splanchnic nerves
-
branches and supply: gives origin to a complex network of small branches which follow the inferior phrenic artery
supplies the diaphragm and adrenal glands
-
relations:
posterior: diaphragmatic crura
lateral: adrenal glands
Variant anatomy
the left ganglia and plexus are absent in most people 1
