It is capable of acting independently of the sympathetic and parasympathetic nervous systems, although it may be influenced by them.
(The enteric nervous system (ENS) is now usually referred to as separate from the autonomic nervous system since it has its own independent reflex activity.)

Neural crest

It is derived from neural crest cells.
Neural crest cells are a temporary group of cells unique to chordates of the group Cristozoa that arise from the embryonic ectoderm cell layer, and in turn give rise to a diverse cell lineage—including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurons and glia.

Autonomic nervous system

autonomicautonomous nervous systemautonomic functions
The enteric nervous system (ENS) or intrinsic nervous system is one of the main divisions of the autonomic nervous system (ANS) and consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract.
The autonomic nervous system has three branches: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

Serotonin

5-HTserotonergic5-hydroxytryptamine
These neurons communicate through many neurotransmitters similar to the CNS, including acetylcholine, dopamine, and serotonin.
Serotonin is primarily found in the enteric nervous system located in the gastrointestinal tract (GI tract).

Prevertebral ganglia

Prevertebral ganglionpre-aortic gangliapreaortic ganglia
The enteric nervous system is capable of operating independently of the brain and spinal cord, but does rely on innervation from the autonomic nervous system via the vagus nerve and prevertebral ganglia in healthy subjects.
Some of the targets present in the pelvic viscera include the enteric nervous system, as well as the renal system, bladder, and any other organs present in the abdomen.

Myenteric plexus

Auerbach's plexusmyentericAuerbach's (Myenteric) plexus
The neurons of the ENS are collected into two types of ganglia: myenteric (Auerbach's) and submucosal (Meissner's) plexuses.
A part of the enteric nervous system, the myenteric plexus exists between the longitudinal and circular layers of muscularis externa in the gastrointestinal tract.

Dogiel cells

cells of DogielDogiel cell
The enteric nervous system in humans consists of some 500 million neurons (including the various types of Dogiel cells), 0.5% of the number of neurons in the brain, five times as many as the one hundred million neurons in the human spinal cord, and about 2/3 as many as in the whole nervous system of a cat.
They play a role in the enteric nervous system.

Gastrointestinal wall

intestinal wallgut wallgastrointestinal tract
Meissner's plexus is a collection of the plexuses of parasympathetic nerves that run from Auerbach's plexus to the muscularis mucosae of the gastrointestinal wall.
It contains the submucous plexus, and enteric nervous plexus, situated on the inner surface of the muscular layer.

European Society of Neurogastroenterology and Motility

The ESNM has over 3,100 European members, who are involved in the study of neuroscience and the pathophysiology of gastrointestinal function, and more generally in the advancement of neurogastroenterology.

Digestive enzyme

The secretion of gastrointestinal enzymes, such as gastrin and secretin, is regulated through cholinergic neurons residing in the walls of the digestive tract.
Secretion by the previous cells is controlled by the enteric nervous system.

Gut–brain axis

gut-brain axisbiochemical signaling that takes place between the gastrointestinal tract and the central nervous systembrain-gut
Broadly defined, the gut–brain axis includes the central nervous system, neuroendocrine and neuroimmune systems, including the hypothalamic–pituitary–adrenal axis (HPA axis), sympathetic and parasympathetic arms of the autonomic nervous system, including the enteric nervous system and the vagus nerve, and the gut microbiota.

Basal electrical rhythm

The physical contractions of the smooth muscle cells can be caused by action potentials in efferent motor neurons of the enteric nervous system, or by receptor mediated calcium influx.
