Pancreas enteric nervous system

The gut contains a collection of nerves called the enteric nervous system. Various activities of the gut, such as peristaltic contractions, and certain activities of the pancreas and gall bladder, are controlled in a manner that is relatively independent of the central nervous system. The central nervous system consists of the brain and spinal cord. Five type,s of activity are controlled by the enteric nervous system (1) contraction of smooth muscles that create the peristaltic waves used to mix and propel food through the intestines (2) release of juices by secretory cells (5) release of hormones from endocrine ceils of the gut (4) patterns of blood flow through the arteries of the gut (variations in blood flow occur because of the opening of blood vessels (vasodilation) or the dosing of blood vessels (vasoconstriction)] and (5) activities of immune cells of the gut (GoyaI and Hirano, 1996).
