Nerve: Auerbach's plexus The myenteric plexus from the rabbit. X 50. LAYERS:
Latin plexus myentericus Gray's subject #248 1177 MeSH Myenteric+Plexus
A part of the enteric nervous system, Auerbach's plexus (or myenteric plexus), exists between the longitudinal and circular layers of muscularis externa in the gastrointestinal tract and provides motor innervation to both layers of the mucosa, having both parasympathetic and sympathetic input, whereas Meissner's plexus has only parasympathetic fibers and provides secretomotor innervation to the mucosa nearest the lumen of the gut.
It arises from cells in the nucleus ala cinerea, the parasympathetic nucleus of origin for the tenth cranial nerve (vagus), located in the medulla oblongata. The fibers are carried by both the anterior and posterior vagal nerves. It is found in the muscles of the esophagus, stomach, and intestine. The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility.
