myenteric plexus

It is also known as the "myenteric plexus".

These cells are connected to the smooth muscle via gap junctions and the myenteric plexus.

Achalasia is due to the loss of ganglion cells of the myenteric plexus.

Gall bladder contraction is regulated by an interaction of the myenteric plexus with intestinal hormones.

The effects of serotonin on gastrointestinal motor function are generally believed to be mediated through myenteric plexus neurons.

The nerve bundles of the submucous plexus are finer than those of the myenteric plexus.

Electron microscopy of the bowel from one of these patients (patient 1) also showed atrophic and shrunken neurones in the myenteric plexus.

The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility.

PAC is expressed in the adrenal medulla, pancreatic acini, uterus, myenteric plexus and brain.

Synaptosomes can also be isolated from tissues other than brain such as spinal cord, retina, myenteric plexus or the electric ray electric organ.

Gershon and Tamir provided convincing data that an intraenteric barrier separates the myenteric plexus from the enterochromaffin cells in the epithelium.

Both command neurons and interneurons are spread throughout two layers of gut tissue called the myenteric plexus and the submuscosal plexus.

A Heller myotomy involves an incision to disrupt the LES and the myenteric plexus that innervates it.

This indicates that somatostatin - and probably also octreotide - has no direct effect on the gall bladder but exerts its inhibitory action by the myenteric plexus.

The lack of ganglion cells is in the myenteric plexus (Auerbach's Plexus), which is responsible for moving food in the intestine.

Neurones in the myenteric plexus were not identified in the colon and were sparse and appeared degenerate in the appendix and ileum.

Loperamide is an opioid-receptor agonist and acts on the μ-opioid receptors in the myenteric plexus of the large intestine; by itself it does not affect the central nervous system.

The myenteric plexus and submucosal plexus are both located in the gut wall and receive sensory signals from the lumen of the gut or the CNS.

It works similarly to morphine, by decreasing the activity of the myenteric plexus, which in turn decreases the tone of the longitudinal and circular smooth muscles of the intestinal wall.

In the remaining three subjects (patients 1, 2, and 3) silver staining revealed a neuropathic abnormality with absent or severely depleted and ill defined argyrophilic neurones in the myenteric plexus.

From this source, they run to the myenteric plexus (Auerbach's plexus) of nerves and ganglia situated between the circular muscular fibers and the longitudinal muscle fibers of the muscularis externa.

In the one subject (patient 4) from whom routine sections only of large bowel and ileum were available, histological examination showed an inflammatory process predominantly affecting the myenteric plexus particularly in the appendix but extending to the small intestine.

Serotonin in mammals is made by two different tryptophan hydroxylases: TPH1 produces serotonin in the pineal gland and the enterochromaffin cells, while TPH2 produces it in the raphe nuclei and in the myenteric plexus.

Biopsy, the removal of a tissue sample during endoscopy, is not typically necessary in achalasia but if performed shows hypertrophied musculature and absence of certain nerve cells of the myenteric plexus, a network of nerve fibers that controls esophageal peristalsis.

All three subjects with a tachygastria (patients 1, 2, and 3) had a proven neuropathy of the myenteric plexus whereas three of the five patients with a continuously irregular frequency of the electrical control activity had clear evidence of a myopathy of the muscle coats on ultrastructural studies.
