Endocrine System and Pancreatic Hormone Secretion Quiz

Hormones and Their Functions

• Glucagon is released by the alpha cells of the endocrine pancreas.
• Insulin's primary target in the body is to regulate glucose levels.
• Somatostatin inhibits the release of both glucagon and insulin.
• Gastrin stimulates the release of hydrochloric acid in response to stomach distention.
• The kidney produces erythropoietin in response to low oxygen levels.

Hormones and Appetite

• Cholecystokinin (CCK) produces a feeling of satiety after a meal, thereby reducing appetite.

Hormones and Organ Function

• The liver secretes insulin-like growth factor, angiotensinogen, thrombopoietin, and hepcidin.

Hormones and Glucose Regulation

• Insulin stimulates glycogenesis in the liver and skeletal muscle, and inhibits enzymes involved in glycogenolysis and gluconeogenesis.
• Glucagon is responsible for stimulating gluconeogenesis, glycogenolysis, and the release of glucose into the circulation, thereby raising blood glucose levels.

Glycogenolysis and Glucose Regulation

• Glycogenolysis is the process of releasing glucose from glycogen stores, and can occur in both the liver and skeletal muscle.

Hormones and Development

• Testosterone is primarily responsible for the development of secondary sex characteristics in males, such as deepened voice, body hair, and increased muscle mass.
