Originally found in the gut, these hormones have since been shown to be present in various parts of the nervous system . Like many other active peptides they are synthesized as larger protein precursors that are enzymatically converted to their mature forms. They are found in several molecular forms due to tissue specific post translational processing. The biological activity of gastrin and CCK is associated with the last five C terminal residues.

They are also considered a type of enteroendocrine cells enteroendocrine cell . ref MeshName Enterochromaffin like Cells ref Function Image Histamine.png thumb left Histamine ECL cells synthesize and secrete histamine . These cells are stimulated by the hormones gastrin and pituitary adenylyl cyclase activating peptide . ECL cells are stimulted by vagal stimulation through the neurotransmitter gastrin releasing peptide . Note that this circuit is not activated by acetylcholine, which is of particular importance because the administration of atropine will not block the vagal stimulation of the G cells, as ACh is not used. Gastrin is transferred from a specific type of G cell in the gastric epithelium to the ECL cells by blood . Histamine and gastrin act synergistically as the most important stimulators of hydrochloric acid secretion from parietal cells and stimulators of secretion of different pepsin s from chief cell s. The most important inhibitor of the ECL cell is somatostatin from oxyntic D cells. Enterochromaffin like cells also produce pancreastatin and probably other peptide hormone s and growth factor s. Pathology A prolonged stimulation of these cells causes their hyperplasia . This is especially important in gastrinoma the tumor s in which there is an excessive secretion of gastrin , as this is one of the factors contributing to Zollinger Ellison s syndrome .

No footnotes date February 2011 The gastrointestinal hormones or gut hormones constitute a group of hormone s secreted by enteroendocrine cell s in the stomach , pancreas , and small intestine that control various functions of the digestive organs. Later studies showed that most of the gut peptides, such as secretin , cholecystokinin or substance P , were found to play a role of neurotransmitter s and neuromodulator s in the central and peripheral nervous systems. Enteroendocrine cells do not form endocrine glands but are spread throughout the digestive tract. They exert their autocrine and paracrine actions that integrate all of gastrointestinal function. Types of Gastrointestinal hormones The gastrointestinal hormones can be divided into three main groups based upon their chemical structure . Gastrin family Gastrin cholecystokinin family gastrin and cholecystokinin Secretin family secretin , glucagon , vasoactive intestinal peptide and gastric inhibitory peptide Somatostatin family Motilin family Substance P . Ghrelin is a peptide hormone released from the stomach and is often referred to as the hunger hormone since high levels of it are found in individuals that are fasting. Ghrelin antagonistic treatments can be used to treat illnesses such as anorexia and loss of appetites in cancer patients. Ghrelin treatments for obesity are still under intense scrutiny and no conclusive evidence has been reached. This hormone stimulates growth hormone release. Cholecystokinin is responsible for gall bladder secretions, gastrointestinal motility as well as pancreatic exocrine secretions. Peptide YY is involved mostly in satiation modulation.

Unreferenced date December 2009 Orphan date October 2008 The Enterogastric reflex is one of three extrinsic reflexes of the Gastrointestinal Tract . The reflex is stimulated by the presence of acid levels in the duodenum at a pH of 3 4 or in the stomach at a pH of 1.5. Upon stimulation of the reflex, the release of gastrin from G cells in the antrum of the stomach is shut off. This in turn inhibits gastric motility and secretion of gastric acid HCl . In addition to the Enterogastric reflex, the other two extrinsic reflexes of the Gastrointestinal Tract include the Gastrocolic reflex and the Colonoileal reflex . Enterogastric reflex activation thus, causes decreased motility.

The cephalic phase of gastric secretion occurs even before food enters the stomach , especially while it is being eaten. It results from the sight, smell, thought, or taste of food, and the greater the appetite , the more intense is the stimulation . Neurogenic signals that cause the cephalic phase of gastric secretion originate from the cerebral cortex and in the appetite centers of the amygdala and hypothalamus .They are transmitted through the dorsal motor nuclei of the vagi and then through the vagus nerve to the stomach. This phase of secretion normally accounts for about 20 percent of the gastric secretion associated with eating a meal. Effects On Gastric Secretion Cephalic phase cause ECL cells to secrete histamine and increase HCl acid in the stomach. There will also be an influence on G cells to increase gastrin circulation.
