The autonomic plexuses of the abdomen are a collection of parasympathetic and sympathetic nerve fibers that coalesce to innervate the viscera of the abdomen.
The major autonomic plexuses of the abdomen are the celiac, superior mesenteric, intermesenteric, inferior mesenteric, and superior hypogastric plexuses. The renal plexus lies along the renal vessels.
The named prevertebral or preaortic ganglia in the abdomen are the paired celiac, the superior mesenteric, paired aorticorenal, and the inferior mesenteric. These ganglia are all sympathetic, of course, since all parasympathetic fibers (below the head, that is) synapse in the wall of the target organ. |  |
