Myenteric plexus

At the time the article was last revised Mostafa Elfeky had no financial relationships to myenteric plexus companies to disclose. The myenteric plexus also known as the Auerbach plexus plural: plexuses refers to a network of nerves between the layers of the muscular propria in the gastrointestinal system, myenteric plexus.

The myenteric plexus or Auerbach's plexus provides motor innervation to both layers of the muscular layer of the gut, having both parasympathetic and sympathetic input although present ganglion cell bodies belong to parasympathetic innervation, fibers from sympathetic innervation also reach the plexus , whereas the submucous plexus provides secretomotor innervation to the mucosa nearest the lumen of the gut. It arises from cells in the vagal trigone also known as the nucleus ala cinerea, the parasympathetic nucleus of origin for the tenth cranial nerve vagus nerve , located in the medulla oblongata. The fibers are carried by both the anterior and posterior vagal nerves. The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility. A part of the enteric nervous system , the myenteric plexus exists between the longitudinal and circular layers of muscularis externa in the gastrointestinal tract. It is found in the muscles of the esophagus, stomach, and intestine. The ganglia have properties similar to the central nervous system CNS.

Myenteric plexus

Myenteric plexus a. Auerbach plexus refers to a local circuitry of neurons and ganglia which is situated within the gut wall from esophagus to the rectum. It is sandwiched between the inner circular and outer longitudinal layers of muscularis externa and innervates the smooth muscle of the gut. The myenteric plexus , in association with another plexus of nerves, called the submucosal plexus, make up the enteric nervous system. The enteric nervous system helps regulate the peristalsis, secretions and vasculature within the gut. While it can act independently from the central nervous system, its activity is primarily regulated by autonomic pre-ganglionic parasympathetic neurons coming from the anterior and posterior vagal trunks. These neurons synapse with the postganglionic parasympathetic neurons of the submucosal and myenteric plexus es in the gut wall. The vagal discharge leads to increased peristalsis and secretions of the gut. Dysfunction of enteric nervous system could lead to various disorders, such as Hirschprung disease, achalasia and gastroparesis. Drake, R.

Among other things, the plexus helps regulate peristalsis in the gastrointestinal tract. In other projects.

Auerbach plexus named after Leopold Auerbach , also known by the name of myenteric plexus, is a group of ganglia that run throughout the entire gastrointestinal tract and innervate its multiple layers of smooth muscle. This collection of nerves is sandwiched between two layers of the muscularis externa, the inner circular muscle layer, and the outer longitudinal muscle. Combined with another set of nerves, the submucosal Meissner plexus, they make up the enteric nervous system. The myenteric plexus is principally responsible for the peristaltic movement of the bowels.

Gastroparesis is a delayed gastric emptying in the absence of mechanical obstruction. Eur J Pediatr Surg. The most important ones responsible for intestinal relaxation are vasoactive intestinal peptide VIP , nitric oxide, pituitary adenylate cyclase-activating peptide, and purine. Hirschsprung disease is a congenital disorder defined by the absence of ganglionic cells in the submucosal and myenteric plexus, also referred to as congenital aganglionic megacolon. It may also be idiopathic, associated with neurological disorders, occur after a viral or bacterial infection, or post-surgical. Category Commons. Log out.

The enteric nervous system ENS or intrinsic nervous system is one of the main divisions of the peripheral nervous system PNS and consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract. The ENS is nicknamed the "second brain".
