What will happen to the levels of TRH and TSH if T3 & T4 are low in the body (a condition known as hypothyroidism)? What causes a goiter in Graves' disease? Does hypothyroidism cause immunodeficiency? How does hypothyroidism cause pleural effusion? Is the thyroid gland an endocrine gland?
An impetus to research into the thyroid subsystem applicable to psychiatric disorders was given by the observation that one of the hormones — thyrotropin-releasing hormone (TRH), which regulates the thyroid subsystem — is secreted by hypothalamus (Prange et al. 1987)....
Thyrotropin-releasing hormone (TRH) is a neurohormone that is secreted by the neuroendocrine or neurosecretory cells of the hypothalamus. TRH acts on the anterior lobe of the pituitary gland and stimulates the release of thyroid-stimulating hormone (TSH)....
One class of hypothalamic hormones is the releasing hormones, which work by stimulating the production of other hormones. For example, the hypothalamus secretes thyrotropin releasinghormone(TRH), which stimulates the pituitary gland to producethyroidstimulating hormone (TSH). TSH causes the thyroid to ...
The hypothalamus and the pituitary gland, which are located in the brain, help control the thyroid gland.The hypothalamus releases thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to release thyroid-stimulating hormone (TSH). ...
How can you tell the difference between secondary and tertiary hypothyroidism? Secondary hypothyroidism occurs when thehypothalamus produces insufficientthyrotropin-releasing hormone (TRH) or the pituitary produces insufficient TSH. Sometimes, deficient TSH secretion due to deficient TRH secretion is termed ter...
现分别向正常人和甲亢病人静脉注射一定剂量的促甲状腺激素释放激素(TRH),并于注射前和注射后连续取血测定血清中促甲状腺激素(TSH)的浓度,请回答下列相关问题: (1)通常采取抽取血样方法来检测内分泌系统的疾病,是利用激素调节具有___的特点。注射TRH后,与正常人相比,甲亢病人的血液中TSH浓度无明显变化的原因是:甲亢...
produces a hormone called thyroxine, and its secretion is controlled by the thyrotropin releasing hormone (trh) from the hypothalamus and the thyroid stimulating hormone (tsh) from the anterior pituitary. when the level of thyroxine in the blood reduces, the hypothalamus stimulates the thyroxine ...
Stimulate the secretion of thyroid hormones from the thyroid gland by binding to a receptor on the surface of the cells of the thyroid (G protein -coupled receptors).TSH is stimulated by TRH hormone of the hypothalamus and is inhibited by Somatostatin hormone, as well as by thyroid hormones ...
The finding that thyrotropin-releasing hormone does not always act as a thyrotropin (TSH)-releasing factor in non-mammalian vertebrates has led researchers... Bert De Groef and Serge Van der Geyten and Veerle M. Darras and Eduard R. Kühn - 《General & Comparative Endocrinology》 被引量: 149...
