Overview: Innervation
The myenteric (Auerbach’s) plexus lies between the layers of the muscularis externa throughout the tubular digestive system, providing autonomic innervation to the smooth muscle of muscularis externa. The plexus is a meshwork of unmyelinated axons and ganglia, whose large neuronal cell bodies give rise to the postganglionic parasympathetic fibers in the plexus. 1000x
