The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior and posterior vagal trunks. The celiac plexus proper consists of the celiac ganglia with a network of interconnecting fibers. The aorticorenal ganglia are often considered to be part of the celiac ganglia, and thus, part of the ...
The celiac ganglia or coeliac ganglia are two large irregularly shaped masses of nerve tissue in the upper abdomen. Part of the sympathetic subdivision of the autonomic nervous system (ANS), the two celiac ganglia are the largest ganglia in the ANS, and they innervate most of the digestive tract .
The celiac, or solar plexus, is located around the celiac trunk and contains the celiac ganglia. The solar plexus is the largest autonomic plexus and provides innervation to multiple abdominal and pelvic organs. The superior mesenteric plexus includes the superior mesenteric ganglia and is located around the superior mesenteric artery.
Celiac ganglia: Lesser splanchnic nerve: T10–T11: Superior mesenteric ganglia and Aorticorenal ganglia: Least splanchnic nerve: T12: Renal plexus: Lumbar splanchnic nerves: L1–2: Inferior mesenteric ganglia, ganglia of intermesenteric and hypogastric plexuses: Sacral splanchnic nerves: sacral part of sympathetic trunk
The superior mesenteric plexus is a continuation of the lower part of the celiac plexus, receiving a branch from the junction of the right vagus nerve with the plexus.. It surrounds the superior mesenteric artery, accompanies it into the mesentery, and divides into a number of secondary plexuses, which are distributed to all the parts supplied by the artery, viz., pancreatic branches to the ...
Abdominal portion of the sympathetic trunk, with the celiac plexus and hypogastric plexus. (Sympathetic trunk labeled at center left.) (Sympathetic trunk labeled at center left.) Scheme showing pathways (white/grey rami are spatially reversed, possibly for clarity?) of a typical spinal nerve.
The superior gastric plexus (gastric or coronary plexus) accompanies the left gastric artery along the lesser curvature of the stomach, and joins with branches from the left vagus nerve. The term "inferior gastric plexus" is sometimes used to describe a continuation of the hepatic plexus .
Its fibers synapse at the celiac ganglia. [4] 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.
