internal secretion - the secretion of an endocrine gland that is transmitted by the blood to the tissue on which it has a specific effect endocrine, hormone secretion - a functionally specialized substance (especially one that is not a waste) released from a gland or cell ACTH, adrenocorticotrophic hormone, adrenocorticotrophin, adrenocorticotropic hormone, adrenocorticotropin, corticotrophin, corticotropin - a hormone produced by the anterior pituitary gland that stimulates the adrenal cortex Adrenalin, adrenaline, epinephrin, epinephrine - a catecholamine secreted by the adrenal medulla in response to stress (trade name Adrenalin); stimulates autonomic nerve action gastrointestinal hormone, GI hormones - hormones that affect gastrointestinal functioning glucagon - a hormone secreted by the pancreas; stimulates increases in blood sugar levels in the blood (thus opposing the action of insulin) gonadotrophic hormone, gonadotrophin, gonadotropic hormone, gonadotropin - hormone secreted by the anterior pituitary gland and placenta; stimulates the gonads and controls reproductive activity insulin - hormone secreted by the isles of Langerhans in the pancreas; regulates storage of glycogen in the liver and accelerates oxidation of sugar in cells melatonin - hormone secreted by the pineal gland neurohormone - a hormone that is released by nerve impulses (e.g., norepinephrine or vasopressin) oxytocin, Pitocin - hormone secreted by the posterior pituitary gland (trade name Pitocin); stimulates contractions of the uterus and ejection of milk parathormone, parathyroid hormone - hormone synthesized and released into the blood stream by the parathyroid glands; regulates phosphorus and calcium in the body and functions in neuromuscular excitation and blood clotting relaxin - hormone secreted by the corpus luteum during the last days of pregnancy; relaxes the pelvic ligaments and prepares the uterus for labor hypothalamic releasing factor, hypothalamic releasing hormone, releasing factor, releasing hormone, RH - any of several hormones produced in the hypothalamus and carried by a vein to the anterior pituitary gland where they stimulate the release of anterior pituitary hormones; each of these hormones causes the anterior pituitary to secrete a specific hormone growth hormone, human growth hormone, somatotrophic hormone, somatotrophin, somatotropic hormone, somatotropin, STH - a hormone produced by the anterior pituitary gland; promotes growth in humans thymosin - hormone secreted by the thymus; stimulates immunological activity of lymphoid tissue thyroid hormone - any of several closely related compounds that are produced by the thyroid gland and are active metabolically ADH, antidiuretic hormone, Pitressin, vasopressin - hormone secreted by the posterior pituitary gland (trade name Pitressin) and also by nerve endings in the hypothalamus; affects blood pressure by stimulating capillary muscles and reduces urine flow by affecting reabsorption of water by kidney tubules sex hormone, steroid hormone, steroid - any hormone affecting the development and growth of sex organs adrenosterone - a steroid having androgenic activity; obtained from the cortex of the adrenal gland glucocorticoid - a steroid hormone that is produced by the adrenal cortex of animals; affects functioning of gonads and has anti-inflammatory activity catecholamine - any of a group of chemicals including epinephrine and norepinephrine that are produced in the medulla of the adrenal gland melanocyte-stimulating hormone, MSH - a hormone secreted by the anterior pituitary gland that controls the degree of pigmentation in melanocytes thyroid-stimulating hormone, thyrotrophic hormone, thyrotrophin, thyrotropic hormone, thyrotropin, TSH - anterior pituitary hormone that stimulates the function of the thyroid gland protirelin, thyrotropin-releasing factor, thyrotropin-releasing hormone, TRF, TRH - hormone released by the hypothalamus that controls the release of thyroid-stimulating hormone from the anterior pituitary
