Hormones - Pancreas

Question 1

Glucagon

Answer 1

• Secreted from alpha (A) cells
• Targets the liver
• Glycogenolysis and gluconeogenesis (increasing glucose levels)

Question 2

Insulin

Answer 2

• Secreted by beta (B) cells
• Target tissue - Diffuse, but mostly liver, fat, and muscle
• Glycogenesis (increases glycogen levels); increases fatty acid
  synthesis; increases glucose and amino acid uptake by tissues

Question 3

Somatostatin
(GHIH)

Answer 3

• Secreted by delta (D) cells
• Targets the pancreas and GI tract
• Inhibits insulin and glucagon secretion; slows absorption of
  nutrients in GI tract

Question 4

Pancreatic
Polypeptide

Answer 4

• Secreted by F cells
• Targets the pancreas and gallbladder
• Inhibits secretion of somatostatin and digestive enzymes in
  pancreas; inhibits gallbladder contraction

Question 5

Grehlin

Answer 5

• Secreted by epsilon (E) cells
• Targets the brain
• Stimulates hunger
