secretin..
It's the master gland that secreat all the homones
the hormone CCK signals the release of leptin, a hormone that tells the brain to signal fullness.
Bilirubin is used by the liver, to make bile
The hormone that predominately signals glucose uptake by the cells is the insulin. It is secreted in the pancreas by the islets of Langerhans.
The hormone that signals the release of glucose from storage is glucagon. Glucagon is produced by the alpha cells of the pancreas and works to increase blood glucose levels when they are low, such as during fasting or between meals.
The sphincter of Oddi (hepatopancreatic sphincter), controls the release of pancreatic enzymes and bile into the duodenum. During digestion, intestinal phase signals stimulate the release of bile.
TSH stands for thyroid stimulating hormone and it signals the release of the thyroid hormones, T3 and thyroxine.
The hormone is called antidiuretic hormone.
The main hormone that signals the release of glucose into the blood is Glucagon, however, it is used in conjunction with other hormones which also cause a release of glucose into the blood. These are somatostatin, Adrenaline (epinephrine for Americans), Cortisol and ACTH.
The gland that sends signals to stop the release of hormones is the pituitary gland, specifically the posterior pituitary. It regulates hormone levels through feedback mechanisms, often in conjunction with the hypothalamus. When hormone levels reach a certain threshold, the pituitary reduces its secretion, thereby inhibiting further hormone release from target glands. This process helps maintain homeostasis in the body.
The primary stimulus for the release of growth hormone (GH) is growth hormone-releasing hormone (GHRH) produced by the hypothalamus. Additionally, factors such as sleep, exercise, stress, and low blood sugar levels can also stimulate GH release. Conversely, somatostatin inhibits its release. Overall, the regulation of GH is a complex interplay of various hormonal signals and physiological conditions.
Receptor molecules are found on cell surfaces and respond to nerve and hormone signals.
