Scientific definitions for somatostatin

[ sō-măt′ə-stătn, sō′mə-tə- ]

A polypeptide produced by the hypothalamus and the pancreas. Somatostatin produced by the hypothalamus acts as a neurohormone that inhibits the secretion of other hormones, especially growth hormone and thyrotropin. Somatostatin secreted by the pancreas acts as a hormone that inhibits the secretion of the other pancreatic hormones, insulin and glucagon, and reduces the activity of the digestive system.
