62thyrotropin-releasing hormone — /thuy reuh troh pin ri lee sing, thuy ro treuh /, Biochem. a small peptide hormone, produced by the hypothalamus, that controls the release of thyrotropin by the pituitary. Also called thyrotropin releasing factor. Abbr.: TRH [1965 70] * * * …
63growth hormone–releasing hormone — (GH RH) a neuropeptide elaborated in the hypothalamus that binds to specific receptors on the somatotrophs of the adenohypophysis and stimulates the secretion of growth hormone. Called also somatocrinin, somatoliberin, and somatotropin releasing… …
64corticotrophin-releasing hormone — a peptide hypothalamic hormone (of 41 amino acids) stimulating the release of ACTH (adrenocorticotrophic hormone) from the anterior pituitary. Its own release is suppressed by a negative feedback loops involving cortisol, and its action is… …
65thyrotrophin-releasing hormone — (TRH) a hormone from the hypothalamus (in the brain) that acts on the anterior pituitary gland to stimulate the release of thyroid stimulating hormone. TRH may be given by intravenous injection to test thyroid gland function and to estimate… …

67thyrotrophin-releasing hormone — TRH a hormone from the hypothalamus (in the brain) that acts on the anterior pituitary gland to stimulate the release of thyroid stimulating hormone. A preparation of TRH (protirelin) may be given by intravenous injection to test thyroid gland… …
68gonadotropin-releasing hormone — GnRH. A hormone made by the hypothalamus (part of the brain). GnRH causes the pituitary gland to make luteinizing hormone (LH) and follicle stimulating hormone (FSH). These hormones are involved in reproduction. Also called GnRH …

70prolactin-releasing hormone — any of various hormones elaborated by the hypothalamus that stimulate the release of prolactin by the adenohypophysis. Most such activity is exerted by vasoactive intestinal peptide, although in humans thyrotropin releasing h. can also have this… …
