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 ...
Auerbach's plexus, also known as the myenteric plexus, is a collection of fibers and postganglionic autonomic cell bodies that lie between the circular and longitudinal layers of the muscularis externa in the gastrointestinal tract. [citation needed] It was discovered and named by German neuropathologist Leopold Auerbach. These neurons provide ...
Between the two muscle layers is the myenteric plexus (Auerbach's plexus). This controls peristalsis. Activity is initiated by the pacemaker cells (interstitial cells of Cajal). The gut has intrinsic peristaltic activity (basal electrical rhythm) due to its self-contained enteric nervous system.
He is credited with the discovery of Plexus myentericus Auerbachi, or Auerbach's plexus, a layer of ganglion cells that provide control of movements of the gastro-intestinal tract, also known as the "myenteric plexus". "Friedreich–Auerbach disease" is named after Auerbach and pathologist Nikolaus Friedreich (1825–1882).
A nerve plexus is a plexus (branching network) of intersecting nerves. [1] ... Auerbach's plexus (myenteric plexus) – serves the gastrointestinal tract;
Myenteric interstitial cells of Cajal (ICC-MY) serve as pacemaker cells that generate the bioelectrical events known as slow waves. [3] Slow waves conduct to smooth muscle cells and cause phasic contractions. [4] [5] An isolated Interstitial cell of Cajal from the myenteric plexus of the mouse small intestine grown in a primary cell culture.
Between the circular and longitudinal muscle layers is the myenteric plexus. This controls peristalsis. Activity is initiated by the pacemaker cells, (myenteric interstitial cells of Cajal). The gut has intrinsic peristaltic activity (basal electrical rhythm) due to its self-contained enteric nervous system.
The myenteric plexus extends the full length of the gut, situated between the circular and longitudinal muscle layers. Beyond its primary motor and secretomotor functions, the myenteric plexus exhibits projections to submucosal ganglia and enteric ganglia in the pancreas and gallbladder, showcasing the interconnectivity within the ENS.
