Effects: Increase histamine and gastrin secretion Increase somatostatin (negative reg) Increase differentiation and proliferation of stomach/colon cells Amidated = all of the above Glycine extended = no acid production |
|
Cholecystekinin
|
Cell: I
Effects: Increase pancreatic growth and bicarb/water secretion Decreases gastric emptying Increases bile secretion |
|
