Which blood glucose-lowering hormone is produced by the pancreatic islet cells?

Question

Quizplus · Accepted Answer

Insulin is the hormone produced by the pancreatic islet cells that helps to lower blood glucose levels by promoting the uptake of glucose by cells and the storage of glucose as glycogen in the liver and muscles. Glucagon, on the other hand, is produced by the pancreas but acts to raise blood glucose levels by stimulating the liver to break down glycogen and release glucose into the bloodstream. Somatostatin is also produced by the pancreas, but it inhibits both insulin and glucagon release, so it does not have a direct effect on blood glucose levels. Thyroid hormones and calcitonin are produced by the thyroid gland and have no direct effect on blood glucose levels.
