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 [[pancreas]]; intestinal branches to the [[small intestine]]; and [[ileocolic]], right colic, and middle colic branches, which supply the corresponding parts of the great intestine.
The nerves composing this plexus are white in color and firm in texture; in the upper part of the plexus close to the origin of the [[superior mesenteric artery]] is a [[ganglion]] ('''ganglion mesentericum superius''').
