Overview: Mucosal innervation
The submucosa of the digestive system is composed of dense connective tissue, possessing an extensive meshwork of axons and ganglia called the submucosal (Meissner’s) plexus. This plexus supplies autonomic innervation to muscularis mucosae and glands. Ganglia in the plexus contain postganglionic parasympathetic nerve cell bodies. Trichrome stain, 100x, 800x
