The pancreas contains islets that secrete hormones involved in regulating blood glucose. Which hormones are produced there?

Pancreatic islets regulate blood glucose through two hormones: insulin and glucagon. Insulin, produced by beta cells, lowers blood glucose by promoting uptake of glucose into muscle and fat and by encouraging the liver to store glucose as glycogen. Glucagon, produced by alpha cells, raises blood glucose by stimulating the liver to break down glycogen and to synthesize glucose (gluconeogenesis), especially during fasting. This push-pull keeps glucose levels steady. The other hormone groups come from different glands: adrenaline and cortisol from the adrenal glands, thyroxine and calcitonin from the thyroid, and estrogen and testosterone from the gonads.
