The enteric nervous system (ENS) regulates many key aspects of the gastrointestinal tract including: motility, secretion and blood flow. In the body region, neural crest cells form the entire enteric nervous system, both neurons and glia, of the gastrointestinal tract.
The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube. These cells migrate to many different locations and differentiate into many cell types within the embryo. This means that many different systems (neural, skin, tooth, head, face, heart, adrenal glands, gastrointestinal tract) will also have a contribution fron the neural crest cells.
Vagal neural crest cells initially migrate into the foregut splanchnic mesoderm of the developing gastrointestinal tract, these cells then migrate caudally along the gut into the midgut. A second population of sacral neural crest cells have been identified as migrating into the region of the hindgut.
The two gastrointestinal plexuses are located between the longitudinal and circular smooth muscle layers (myenteric plexus, Auerbach's plexus) and in the submucosal layer (submucosal plexus, Meissner's plexus). Interstitial cells of Cajal (ICCs) within the myenteric plexus are pacemaker cells that control peristaltic contraction waves.

Interstitial Cells of Cajal
Interstitial cells of Cajal (ICCs) are located within the gastrointestinal tract and also within the pancreas, placenta, and female reproductive tract.
Interstitial cells of Cajal (ICCs) Subtypes
- ICCdmp - deep muscular plexus region between the circular thin and thick muscle layers, only in the small intestine.
- ICCim - intramuscular located in the circular and longitudinal muscle layers, mediate motor neuronal input.
- ICCmy - myenteric plexus are the primary pacemaker cells in the small intestine, generating and propagating the electrical slow waves.
- ICCss subserosal found in the small intestine and colon (around the submucosa of the pylorus and colon).
- week 7 - rostro-caudal neural crest cell colonization of the gut complete and differentiated into neurons and glia. Interstitial cells of Cajal (ICCs) localized in the ganglion plexus.
- foregut neurons and glia were aggregated into ganglion plexus (myenteric region) not in submucosa.
- hind gut neurons and glia are dispersed within the mesenchyme.
- week 9 - myenteric plexus, longitudinal and circular muscle layers formed along the entire gut.
- week 12 - scattered and individual neurons and glia, and small ganglion plexuses were detected in the foregut and midgut submucosa. Muscularis mucosae formed at the foregut and midgut.
- week 14 - ganglion plexus seen in the hind gut submucosa. Muscularis mucosae formed at the hindgut.
- week 20 - ICCs preferentially localized at the periphery of the plexus.
Mouse enteric plexus GFP
In the chicken gut, neural crest cells from both vagal (somite level 1-7) and sacral (somite level 28 and posterior) levels differentiate into the neurons and glial cells of the enteric nervous system.
See also Nicole Le Douarin's research.
(myenteric plexus) In 1864 Auerbach first described the neural plexus lying between the longitudinal and circular smooth muscle layers of the gastrointestinal tract. The plexus has both parasympathetic and sympathetic input and is involved in the rhythmic peristaltic contractions of the gut wall. Plexus named after Leopold Auerbach (1828 – 1897) a German anatomist and neuropathologist born in Breslau.
(submucosal plexus) Part of the enteric nervous system lying in the submucosa layer of the gastrointestinal tract is associated with mucosal secretion (secretomotor). Embryologically derived from neural crest cells. Named after Georg Meissner (1829-1905) a German histologist, physiologist and anatomist.

LB16.1 Hirschsprung disease
|ICD-11 LB16.1 Hirschsprung disease - This is a developmental anomaly affecting the intestinal tract characterized by congenital absence of myenteric ganglion cells (aganglionosis) in a segment of the large bowel. Due to the absence of intrinsic innervation of the muscle layers of the affected segment, there is a loss of motor function. This results in an abnormally large or dilated colon (congenital megacolon) with intestinal occlusion or constipation. This condition becomes evident shortly after birth.|
Hirschsprung disease (intestinal aganglionosis, Hirschsprung's disease, aganglionic colon, megacolon, congenital aganglionic megacolon, congenital megacolon) is a condition caused by the lack of enteric nervous system (neural ganglia) in the intestinal tract responsible for gastric motility (peristalsis). In general, its severity is dependent upon the amount of the GIT that lacks intrinsic ganglia, due to developmental lack of neural crest migration into those segments. (More? neural crest abnormalities)
Historically, Hirschsprung's disease takes its name from Dr Harald Hirschsprung (1830-1916) a Danish pediatrician (of German extraction). In 1886, he presented at the German Society of Pediatrics conference in Berlin a case of 2 infants who died of complications of bowel obstruction (H. Hirschsprung, Stuhltragheit Neugeborener in Folge von Dilatation und Hypertrophie des Colons, Jhrb f Kinderh 27 (1888), pp. 1-7). Later autopsies identified a dilatation and hypertrophy of large intestine, and the rectum appeared normally narrow. Hirschsprung suggested that the condition was an inborn disease and named it congenital megacolon.
The first indication in newborns is an absence of the first bowel movement, other symptoms include throwing up and intestinal infections. Clinically this is detected by one or more tests (barium enema and x ray, manometry or biopsy) and can currently only be treated by surgery. A temoporary ostomy (Colostomy or Ileostomy) with a stoma is carried out prior to a more permanent pull-through surgery.

|Short section of the colon without smooth muscle neural ganglia||Aganglionic segment removed||Reattachment|
Hirschsprung’s disease (1.3 per 10,000 births) ICD-10 Q43.1
- A condition characterised by partial or complete bowel obstruction resulting from absence of peristalsis in a segment of bowel due to an aganglionic section of the bowel.
- More than two-thirds (66.7%) of the babies born with this anomaly were males.
- Women aged 40 years or older had the highest rate of affected pregnancies.
