|Nerve: Phrenic plexus|
The celiac ganglia with the sympathetic plexuses of the abdominal viscera radiating from the ganglia. (Phrenic plexus labeled at upper left.)
It arises from the upper part of the celiac ganglion, and is larger on the right than on the left side.
It receives one or two branches from the phrenic nerve.
At the point of junction of the right phrenic plexus with the phrenic nerve is a small ganglion (ganglion phrenicum).
