  2. Submucosal plexus - Wikipedia

    en.wikipedia.org/wiki/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. Branches from the myenteric plexus ...

  3. Myenteric plexus - Wikipedia

    en.wikipedia.org/wiki/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 ...

  4. Enteric nervous system - Wikipedia

    en.wikipedia.org/wiki/Enteric_nervous_system

    Layers of the Alimentary Canal.The wall of the alimentary canal has four basic tissue layers: the mucosa, submucosa, muscularis, and serosa. The enteric nervous system in humans consists of some 500 million neurons [11] (including the various types of Dogiel cells), [1] [12] 0.5% of the number of neurons in the brain, five times as many as the one hundred million neurons in the human spinal ...

  5. Hirschsprung's disease - Wikipedia

    en.wikipedia.org/wiki/Hirschsprung's_disease

    This lack of ganglion cells in the myenteric and submucosal plexus is well documented in Hirschsprung's disease. [9] With Hirschsprung's disease, the segment lacking neurons (aganglionic) becomes constricted, causing the normal, proximal section of bowel to become distended with feces.

  6. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    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.

    en.wikipedia.org/wiki/Wikipedia:Osmosis/Hirsch...

    The myenteric plexus connects with the second plexus—the submucous plexus, or also known as Meissner’s plexus, which is buried in the submucosa and is responsible for helping to control blood flow and epithelial cell absorption and secretion. These groups of nerves are clearly super important for normal bowel function.

  9. Nerve plexus - Wikipedia

    en.wikipedia.org/wiki/Nerve_plexus

    The brachial plexus is formed by the ventral rami of C5-C8-T1 spinal nerves, and lower and upper halves of C4 and T2 spinal nerves. The plexus extends toward the armpit. The ventral rami of C5 and C6 form upper trunk, the ventral ramus of C7 forms the middle trunk, and the ventral rami of C8 and T1 join to form the lower trunk of the brachial ...
