1 Somatostatin inhibits growth hormone release in response to GHRH and to other stimulatory factors such as low blood glucose concentration. 2  Ghrelin is a peptide hormone secreted from the stomach. 3  Ghrelin binds to receptors on somatotrophs and potently stimulates secretion of growth hormone.
Some of the signals which trigger the release of hormones include: Hormones from other endocrine glands - Most hormones are released as a result of another hormone being released. For example, thyrotropin releasing hormone (TRH) triggers the release of thyroid stimulating hormone (TSH), which, in turn, triggers the release of thyroxine from the thyroid gland. Blood composition - For example, insulin is released by the pancreatic beta cells in response to a rise in blood sugar after a meal.
