|
Gastrin cell? |
G cells in stomach and upper small intestine in response to products of digestion, extrinsic nerve stimulation (Vagus), astral distension (PSNS ACh and GRP, ENS ACh). |
|
|
Gastrin effect? |
Increase secretion of HCL, pepsinogen, intrinsic factor. Trophic effect on gastric acid secreting mucosa. |
|
|
CCK cell? |
I cell in upper intestine in response to products of digestion (fat, protein,...) |
|
|
CCK effect? |
- Contraction of gall bladder -release of zymogen granules from acing cell soft pancreas. -Relaxation of the sphincter of Oddi -Trophic effect on pancreatic acinar cells. -Increased gastric emptying. |
|
|
Secretin cell? |
S cell in upper intestine in response to FA and decreased pH |
|
|
Secretin effect? |
-Increased bile flow from liver and pancreatic ducts (H2O and HCO3-) |
|
|
GIP cells?
|
K cells in upper small intestine in response to fat, amino acids and proteins.
|
|
|
GIP effect? |
Release of insulin from the beat cells of pancreas |
|
|
Proglucagon derived peptides,enteroglucoagon, GLP cells? |
L cells in distal ileum and colon in response to glucose and fat. |
|
|
Proglucagon derived peptides,enteroglucoagon, GLP effect? |
Enhanced intestinal uptake of glucose, trophic effect on intestinal crypt cells. |
|
|
Somatostatin cells? |
D cells in stomach in response to H+ D cells in proximal stomach in response to CCK and Ach D cells in intestine and pancreatic islets in response to glucose, fat and bile salts in intestinal lumen |
|
|
Somatostatin effects? |
Stomach: decreased gastrin release Proximal stomach: decreased gastric acid, histamine, pepsinogen secretion + inhibit trophic effect of gastrin Intestine/pancreas: decreased pancreatic enzyme secretion, insulin and glucagon release. |
