Neural and hormonal regulation of pancreatic secretion

Neural hormonal regulation of exocrine pancreatic secretion.

Exocrine pancreatic secretion is regulated by hormone-hormonal and neural-hormonal interactions involving several regulatory peptides and neurotransmitter from the gut, the pancreas and the vagus nerve. The roles of the gastrointestinal peptides including secretin, CCK, neurotensin, motilin, PYY and pancreatic islet hormones including insulin, pancreatic polypeptide and somatostatin have been e...

Neural, hormonal, and paracrine regulation of gastrin and acid secretion.

Physiological stimuli from inside and outside the stomach coverage on gastric effector neurons that are the primary regulators of acid secretion. The effector neurons comprise cholinergic neurons and two types of non-cholinergic neurons: bombesin/GRP and VIP neurons. The neurons act directly on target cells or indirectly by regulating release of the hormone, gastrin, the stimulatory paracrine a...

Hormonal Regulation of Bile Secretion

Hormones transported to the liver by the portal and systemic circulation regulate many hepatic functions. The mechanisms by which these hormones regulate gene expression and protein functions have been under intensive investigation in recent years. It is clear that hepatic metabolic responses to steroid and peptide hormones are generally similar to those for other hormone-sensitive tissues. Thu...

Regulation of Pancreatic Secretion

The exocrine pancreas secretes digestive enzymes, fluid, and bicarbonate in response to food ingestion. This is a critical digestive process that is regulated by neural reflexes, gastrointestinal hormones, and absorbed nutrients. Secretion is highly regulated by both stimulatory and inhibitory influences that coordinate the delivery of digestive enzymes with food emptying into the intestine to ...
