The suprarenal plexus is formed by branches from the celiac plexus, from the celiac ganglion, and from the phrenic and greater splanchnic nerves, a ganglion being formed at the point of junction with the latter nerve.
The nerve contributes to the celiac plexus, a network of nerves located in the vicinity of where the celiac trunk branches from the abdominal aorta. The greater splanchnic nerve modulates the activity of the enteric nervous system of the foregut. It stimulates contraction of the splanchnic vasculature, increasing blood pressure. [5]
The adrenal medulla (Latin: medulla glandulae suprarenalis) is the inner part of the adrenal gland. [1] It is located at the center of the gland, being surrounded by the adrenal cortex. [1]
The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar splanchnic nerve and aortic plexus. [1] The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them.

A blunt injury to the celiac plexus normally resolves with rest and deep breathing. A celiac plexus block by means of fluoroscopically guided injection is sometimes used to treat intractable pain from cancers [2] such as pancreatic cancer. Such a block may be performed by pain management specialists and radiologists, with CT scans for guidance.
The plexus receives pre-ganglionic parasymathetic afferents primarily [1] from the anterior vagal trunk, [1] [2] with a lesser contribution from [1] the posterior vagal trunk. [1] [2] The anterior vagal trunk issues one or more hepatic branches of anterior vagal trunk that pass in the superior portion of the lesser omentum to reach the hepatic plexus.
The superior hypogastric plexus receives contributions from the two lower lumbar splanchnic nerves (L3-L4), which are branches of the chain ganglia. They also contain parasympathetic fibers which arise from pelvic splanchnic nerve (S2-S4) and ascend from inferior hypogastric plexus; it is more usual for these parasympathetic fibers to ascend to the left-handed side of the superior hypogastric ...
