Question 1

increases gastric H secretion, stimulates growth of gastric mucosa. for this hormone, what are its stimulators and inhibitors?

Answer 1

Gastrin

stimulated by:
small peptides
amino acids 
distention of the stomach
vagus- GRP 

inhibited by:
H in the stomach and Somatostatin

Question 2

stimulates contraction of gallbladder, relaxation of the oddi sphincter, increases pancreatic HCO3, growth of exocrine pancreas/gallbladder, and inhibits gastric emptying. for this compound, what are its stimulators and inhibitors?

Answer 2

CCK from I cells in the Duodenum and Jejunum

stimulated by:
small peptides
amino acids
fatty acids

inhibited by (not given)
