(ENS) neural network within the gastrointestinal tract wall that locally controls and coordinates intestinal functions (motility, epithelial secretion and blood flow) derived mainly from the neural crest. (More? Neural Crest Notes

controls the gut musculature and is part of the autonomic nervous system

The nervous system of the gut, i.e., the neuronal networks of the submucosal and myenteric (Auerbach's) plexuses in the walls of the gut. A variety of experiments show that this nervous system can function essentially normally in the absence of autonomic inputs, whose effects are modulatory.

portion of the nervous system pertaining to the small intestines; plays a role in most digestive disorders

A set neurons within the wall of the digestive tract that regulate many aspects of digestive function.

The local nervous system of the digestive tract.

The enteric nervous system (ENS) is the part of the nervous system that directly controls the gastrointestinal system. It is capable of autonomous functions such as the coordination of reflexes, although it receives considerable innervation from the autonomic nervous system and thus is often considered a part of it. Its study is the focus of neurogastroenterology.
