By another definition, local hormones are any hormones acting in a paracrine , autocrine signalling autocrine , and or intracrine manner. Classification According to structural and functional similarity, many local hormones fall into either the gastrin or the secretin family.

Migrating motor complexes or migrating myoelectric complex or migratory motor complex or migratory myoelectric complex or MMC are waves of activity that sweep through the intestines in a regular cycle during fasting state. These motor complexes help trigger peristalsis peristaltic wave s, which facilitate transportation of indigestible substances such as bone, fiber, and foreign bodies from the stomach , through the small intestine , past the ileocecal sphincter , and into the colon anatomy colon . The MMC originates in the stomach roughly every 75 to 90 minutes during the interdigestive phase between meals and is responsible for the Borborygmus rumbling experienced when hungry. The MMC lasts for approximately 15 minutes. It also serves to transport bacteria from the small intestine to the large intestine , and to inhibit the migration of colonic bacteria into the terminal ileum. The MMC is thought to be partially regulated by motilin , which is initiated in the stomach as a response to Vagus nerve vagal stimulation, and does not directly depend on extrinsic nerves.

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. Pancreatic polypeptide function is most apparent in control of gastrointestinal motility and satiation Amylin controls glucose homeostasis and gastric motility Glucose dependent insulinotropic polypeptide possesses an acute influence on food intake through its effects on adipocytes Glucagon like peptide 1 has an effect on incretin activit ... more details
