The enteric nervous system in humans consists of some 500 million neurons [11] (including the various types of Dogiel cells), [1] [12] 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, [13] and about 2 ⁄ 3 as many as in the whole nervous system of a cat. The enteric ...
The enteric nervous system also makes use of more than 30 neurotransmitters, most of which are identical to the ones found in CNS, such as acetylcholine, dopamine, and serotonin. More than 90% of the body's serotonin lies in the gut, as well as about 50% of the body's dopamine; the dual function of these neurotransmitters is an active part of ...
The anatomical basis of the gut–memory connection includes the gastrointestinal tract (GIT), which has its own intrinsic nervous system, called the enteric nervous system (ENS). The ENS controls intestinal function and can theoretically operate independently from the central nervous system (CNS). [15]
A part of the enteric nervous system, the myenteric plexus exists between the longitudinal and circular layers of muscularis externa in the gastrointestinal tract. It is found in the muscles of the esophagus, stomach, and intestine. [citation needed] The ganglia have properties similar to the central nervous system (CNS). These properties ...
The enteric nervous system directly controls the gut motility, whereas the extrinsic nerve pathways influence gut contractility indirectly through modifying this enteric innervation. [3] In almost all cases of neurogenic bowel dysfunction it is the extrinsic nervous supply affected and the enteric nervous supply remains intact.
The digestive system has a complex system of motility and secretion regulation which is vital for proper function. This task is accomplished via a system of long reflexes from the central nervous system (CNS), short reflexes from the enteric nervous system (ENS) and reflexes from GI peptides working in harmony with each other.

Enteric neuropathy is a degenerative neuromuscular condition of the digestive system. [1] In simple terms the gut stops functioning, due to degradation of the nerves and muscles. The condition affects all parts of the digestive tract. There is no known cure or treatment for enteric neuropathy at this time; it is only possible to work on symptom ...
