Description
The superior mesenteric ganglion is a prevertebral sympathetic ganglion of the abdomen. It is located at the root of the superior mesenteric artery as it emerges from the aorta. The superior mesenteric ganglion may be interconnected with the celiac ganglia.
The superior mesenteric ganglion receives primary input from preganglionic lesser thoracic splanchnic nerve, and postganglionic fibers form the superior mesenteric plexus. In this way, it provides sympathetic innervation of the vascular territory of the superior mesenteric artery, the midgut.
