301-GI Hormones
Question | Answer |
---|---|
GASTRIN | PROTEINS stimulate G CELLS(OF THE STOMACH) to release GASTRIN which releases HISTAMINE(BY ECL) AND ACID(BY PARIETAL) |
SOMATOSTATIN | ACIDIC CONDITIONS stimulate D CELLS(OF THE STOMACH) to release SOMATOSTATIN which inhibits ACID RELEASE(BY PARIETAL) |
SECRETIN | ACIDIC CONDITIONS stimulate S CELLS(IN THE SI) to release SECRETIN which stimulate DUCTAL PANCREAS CELLS to release BICARBONATE. |
CCK | FATTY ACIDS AND PROTEINS stimulate I CELLS(IN THE SI) to release CCK which stimulate ACINAR PANCREAS CELLS to release NA, CL, K, BICARB, AND DIGESTIVE ENZYMES. ALSO GALL BLADDER CONTRACTION AND ODI RELAXATION. |
PEPTIDE YY | FATTY ACIDS, GLUCOSE, AND PROTEINS stimulate L CELLS(IN THE SI) to release PEPTIDE YY which inhibits ALL GI SECRETIONS |
GIP | FATTY ACIDS AND GLUCOSE stimulate K CELLS(IN THE SI) to release INSULIN |
GLP 1-2 | FATTY ACIDS, GLUCOSE, AND PROTEINS stimulate L CELLS(IN THE SI) to release GLP which MAINTAINS GLUCOSE HOMEOSTASIS AND EPITHLIAL CELL PROLIFERATION |
