Overview: Innervation
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
