Document Summary

Insulinotropic peptide (gip: secretin, s c ells, circular movement opens where the food is, contracts before the food, pushing motion, segmentation= mixing. 1 target cell: cck, triggered by fatty acid and aa in the small intestine it will make the pancreas secrete more enzymes and make the gall bladder contract to help them be absorbed, presence of peptide/ amino acids, will increase hcl release and stomach motility, small intestine, found in k cells, sees glucose and releases insulin, sees acidic environment enter the small intestine, this is bad. It stops hcl and stomach motility, and increases bicarbonate secretion: pacemaker slow wave cells, but need hormonal input to go from spontaneous depol to an action potential that meets threshold, the # ap fired is proportional to the force of contraction to neural input. Stomach will activiate cck, secretin, and gip: anorexigenic (less intake) , leptin (adipose), insulin (pancreas), peptide yy (intestine), melanocortin (hypothalamus).
