Abnormal enteric nervous system morphology

What it means

A structural anomaly of nerves of the enteric nervous system.

The enteric nervous system represents a collection of about 500 million neurons that control virtually all gut functions (including motility), largely independent from the central nervous system. The enteric nervous system is located in the gut wall and extends throughout its length from the esophagus to the internal anal sphincter.
