Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Auerbach's plexus or myenteric plexus provides motor innervation to both layers of the tunica muscularis, having both parasympathetic and sympathetic input, whereas Meissner's plexus has only parasympathetic fibers and provides secretomotor innervation to the mucosa nearest the lumen of the gut. A few studies, however, failed to show evidence of infection as a cause for achalasia[ 2526 ].

The myenteric plexus (or Auerbach's plexus) provides motor innervation to both layers of the The myenteric plexus is the major nerve supply to the gastrointestinal tract and It is found in the muscles of the esophagus, stomach, and intestine. The myenteric plexus functions as a part of the enteric nervous system.

Screening the genome for rheumatoid arthritis susceptibility genes: a replication study and combined analysis of multicase families. The disease is likely to be multi-factorial involving host genetic factors, autoimmunity, and environmental factors such as infections. Achalasia is an esophageal motor disorder characterized by aperistalsis of the esophageal body and lack of relaxation of the lower sphincter in response to swallows.
