|
|
phenylalanine & tryptophan stimulate:
|
gastrin
|
|
|
increased by fatty acids, amino acids, oral glucose
|
GIp
|
|
|
increased by acid, decreased by vagal stimulation

somatostatin
|
|
|
increased by acid, fatty acid in lumen of duodenum
|
secretin
|
|
|
increased by fatty acids and amino acids
|
CCK
|
|
|
increased by stomach distention, amino acids, peptides, vagal stimulation. decreased by stomach pH <1.5
|
gastrin
|
|
|
increased by distention and vagal stimulation
decreased by adrenergic input |
VIP
|
|
|
action: decreases gastric acid secretion and increases insulin release
|
GIP
|
|
|
action: increases intestinal water and electrolyte secretion, increases relaxation of intestinal smooth muscle and sphincters
|
VIP
|
|
|
reason why oral load of glucose is used more rapidly than equiv by IV
|
GIP
|
