Quick Summary
The superior mesenteric ganglion is one of three preaortic ganglia that are part of the sympathetic nervous system. These ganglia are located on the anterior surface of the aorta and distribute axons with the major arteries originating from it. Specifically, the superior mesenteric ganglion innervates the small intestine. The sympathetic nervous system is a division of the autonomic nervous system, which regulates involuntary bodily functions and prepares the body for "fight-or-flight" responses.12
