Regarding this, what is the main function of the myenteric plexus?

The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility. According to preclinical studies, 30% of myenteric plexus' neurons are enteric sensory neurons, thus Auerbach's plexus has also a sensory component.

Subsequently, question is, what is the submucosal plexus? The submucosal plexus (Meissner's plexus, plexus of the submucosa, plexus submucosus) lies in the submucosa of the intestinal wall. The nerves of this plexus are derived from the myenteric plexus which itself is derived from the plexuses of parasympathetic nerves around the superior mesenteric artery.

Subsequently, question is, what does the myenteric plexus regulate?

The myenteric plexus controls primarily motility; the submucosal plexus controls primarily fluid secretion and absorption. More than 20 distinct neurotransmitters have been identified in enteric neurons (e.g., ACh, substance P, serotonin, VIP, somatostatin, nitric oxide).

What is the mesenteric plexus?

Medical Definition of mesenteric plexus : either of two plexuses of the sympathetic nervous system lying mostly in the mesentery in close proximity to and distributed to the same structures as the corresponding mesenteric arteries: a : one associated with the inferior mesenteric artery.
