| hormone,t4 | Thyroxine, a thyroid hormone. The number 4 is usually in subscript. (12 Dec 1998) |
| hormone therapy | Treatment which results in the raising or lowering of hormone levels. Changes in levels can effect some breast cancers, those that need hormones for growth. (16 Dec 1997) |
| hormone, thyroid | Chemical substance made by the thyroid gland which is located in the front of the neck. The thyroid gland uses iodine to make thyroid hormones. The two most important thyroid hormones are thyroxine (t4) and triiodothyronine (t3). (12 Dec 1998) |
| hormone, thyroid stimulating | A hormone produced by the pituitary gland (at the base of the brain) that promotes the growth of the thyroid gland (in the neck) and stimulates it to produce its thyroid hormones. Normally, the rate of thyroid hormone production is controlled by the pituitary. When there are insufficient thyroid hormones in the body for normal functioning of the cells, the pituitary releases tsh. Tsh in turn stimulates the thyroid gland to produce more thyroid hormones. In contrast, when there is excessive amount of thyroid hormones, the pituitary gland stops producing tsh. The tsh level then falls and thyroid hormone production is reduced. This mechanism maintains a relatively constant level of thyroid hormones circulating in the blood. This phenomenon is analogous to a thermostat used for temperature regulation in a room: when the temperature rises, the thermostat shuts the heater off and the room temperature falls back to normal. High levels of thyroid hormones cause the tsh level to fall, resulting in no further stimulation of the thyroid gland. In hyperthyroidism, there are continuously elevated levels of the thyroid hormones. Tsh is also known as thyrotropin. (12 Dec 1998) |
| hormone, thyrotropin | A hormone produced by the pituitary gland (at the base of the brain) that promotes the growth of the thyroid gland (in the neck) and stimulates it. The suffix -tropin indicates an affinity for. Thyrotropin has an affinity for the thyroid. Thyrotropin is known also as thyroid stimulating hormone (tsh). (12 Dec 1998) |
| hormone, thyroxine | A chemical substance made by the thyroid gland the thyroid gland uses iodine to make thyroid hormones. Thyroxine (t4), one of the most important thypoid hormones, has four iodine molecules attached to its molecular structure. (12 Dec 1998) |
| hormone, triiodothyronine | A hormone made by the thyroid gland. The thyroid gland uses iodine to make thyroid hormones. Triiodothyronine (t3) has three iodine molecules attached to its molecular structure. Iodine is found in seafood, bread, seaweed, and ordinary table salt. (12 Dec 1998) |
| hormone, tsh | Stands for Thyroid Stimulating Hormone. Also known as thyrotropin. (12 Dec 1998) |
| human chorionic somatomammotropic hormone | human placental lactogen |
| human growth hormone | <endocrinology> A protein produced in the pituitary gland that stimulates the liver to produce somatomedins, which stimulate growth of bone and muscle. (09 Oct 1997) |
| sex hormone | <endocrinology> Hormone that is secreted by gonads or that influences gonadal development. Examples are oestrogen, testosterone, gonadotrophins. (18 Nov 1997) |
| sex hormone-binding globulin | A glycoprotein migrating as a beta-globulin. Its molecular weight, 52,000 or 95,000-115,000, indicates that it exists as a dimer. The protein binds testosterone, dihydrotestosterone, and estradiol in the plasma. Changes in its concentration significantly affect the ratio of unbound (biologically active) testosterone to estradiol in plasma. (12 Dec 1998) |
| hypophysiotropic hormone | A hormone that stimulates the rate of secretion of hypophysial hormone's; e.g., a releasing factor. (05 Mar 2000) |
| somatotropic hormone | <protein> Hormone (191 amino acids) released by anterior pituitary that stimulates release of somatomedin, thereby causing growth. (18 Nov 1997) |
