5 Cards in this Set

  • Front
  • Back
Gastrin
Produced by: enteroendocrine cells of stomach
Target: stomach muscle, gastric glands
Function : increase stomach motility, increase gastric gland secretions
Regulated by: increased by increase in stomach pH due to presence of proteins/food, parasympathetic
NS
Cholecystokinin
Produced by: enteroendocrine cells of duodenum
Target: liver, pancreas, gallbladder, hepatopancreatic sphincter
Function: increase secretion of pancreatic enzymes, contact gallbladder to release bile, increase bile
production and release from the liver, open hepatopancreatic sphincter.
Regulated by: increase in release when increase fally chime in duodenum, especially if protein-rich
Secretin
Produced by: enteroendocrine cells of duodenum
Target: stomach, pancrease and liver
Function: decrease stomach motility and gastric secretions, increase bicarbonate release from pancreas,
increase bile production
Regulated by: increase in release when increase fally chime in duodenum, especially if protein-rich
Insulin
Produced by: pancreas
Target: most cells especially muscle cells
Function: decrease blood glucose levels by increasing cellular uptake and use of glucose for glycogenolysis, lipogenesis, and protein synthesis
Secretion regulated by: concentrations of glucose, fats and amino acids in the blood, and somatostatin.
glucagons
Produced by: pancreas
Target: liver hepatocytes
Function: increase blood glucose levels by glycogenolysis and gluconeogenesis
Secretion regulated by: concentrations of glucose and amino acids in the blood, and somatostatin.
