Although its name may sound lighthearted, restless leg syndrome (RLS) can be a troubling disorder. Symptoms include itching, burning, or aching in the legs, particularly when youâre at rest, and an overwhelming desire to move your legs.
secretin. a hormone secreted by the mucosa of the duodenum and jejunum when acid chyme enters the intestine; carried by the blood, it stimulates the secretion of pancreatic juice and, to a lesser extent, bile and intestinal secretion.secretin test. hormone, formed by the epithelial cells of the duodenum under the stimulus of acid contents from the stomach, which incites secretion of pancreatic juice; used as a diagnostic aid in the diagnosis of pancreatic exocrine disease and as an adjunct in obtaining desquamated pancreatic cells for cytologic examination.
Primary hormones secreted by the pancreas include: 1  Gastrin: This hormone aids digestion by stimulating certain cells in the stomach to produce acid. 2  Glucagon: Glucagon helps insulin maintain normal blood glucose by working in the opposite way of insulin. It stimulates your cells to release glucose, and this raises your blood glucose levels. Insulin: This hormone regulates blood glucose by allowing many of your bodyâs cells to absorb and use glucose. In turn, this drops blood glucose levels. Somatostatin: When levels of other pancreatic hormones, such as insulin and glucagon, get too high, somatostatin is secreted to maintain a balance of glucose and/or salt in the blood. Vasoactive intestinal peptide (VIP): This hormone helps control water secretion and absorption from the intestines by stimulating the intestinal cells to release water and salts into the intestines.
