Thyroid-stimulating hormone From Wikipedia, the free encyclopedia. Thyroid-stimulating hormone (also known as thyrotropin, TSH, or hTSH for human TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T 4), and then triiodothyronine (T 3) which stimulates the metabolism of almost every tissue in the body.timulation of the receptor increases T 3 and T 4 production and secretion. Stimulating antibodies to this receptor mimic TSH and cause Graves' disease. In addition, hCG shows some cross-reactivity to the TSH receptor and therefore can stimulate production of thyroid hormones.

BenzoBuddies Community Forum The hypothalamic–pituitary–thyroid axis (HPT axis for short, aka thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland.The hypothalamus senses low circulating levels of thyroid hormone (Triiodothyronine (T3) and Thyroxine (T4)) and responds by releasing thyrotropin-releasing hormone (TRH).he TRH stimulates the pituitary to produce thyroid-stimulating hormone (TSH). The TSH, in turn, stimulates the thyroid to produce thyroid hormone until levels in the blood return to normal.

Thyroid-Stimulating Hormone (Thyrotropin) Thyroid-Stimulating Hormone (Thyrotropin) Thyroid-stimulating hormone, also known as thyrotropin, is secreted from cells in the anterior pituitary called thyrotrophs, finds its receptors on epithelial cells in the thyroid gland, and stimulates that gland to synthesize and release thyroid hormones.

The thyroid hormone effects on growth and development may be mediated by growth factors. Thyroid hormone binding to nuclear receptors is known to stimulate growth hormone (GH) synthesis, and thyroid hormones probably potentiate GH stimulation of SM production as well as the anabolic effects of SM.

Control of Thyroid Hormone Synthesis and Secretion Thyroid-releasing hormone (TRH) from the hypothalamus stimulates TSH from the pituitary, which stimulates thyroid hormone release. As blood concentrations of thyroid hormones increase, they inhibit both TSH and TRH, leading to shutdown of thyroid epithelial cells.

My Thyroid Does What? The pituitary gland releases Thyroid Stimulating Hormone (TSH), which travels directly to the thyroid gland. This hormone stimulates the thyroid gland to produce the two main hormones, T3 and T4. T3 is the more active and usable form of thyroid hormone, but only 7% of the thyroid hormones produced are in the T3 form. 93% of thyroid hormone produced is T4. T4 must be converted into T3 to become useful for the body.

The Pituitary Gland and Hypothalamus Thyroid-Stimulating Hormone. The activity of the thyroid gland is regulated by thyroid-stimulating hormone (TSH), also called thyrotropin. TSH is released from the anterior pituitary in response to thyrotropin-releasing hormone (TRH) from the hypothalamus. As discussed shortly, it triggers the secretion of thyroid hormones by the thyroid gland.

- Thyroid hormone production is regulated by thyroid-stimulating hormone (TSH), which is made by the pituitary gland in the brain. When thyroid hormone levels in the blood are low, the pituitary releases more TSH. When thyroid hormone levels are high, the pituitary responds by dropping TSH production.

The Anterior Lobe As its name suggests, TSH stimulates the thyroid gland to secrete its hormone thyroxine (T4). It does this by binding to transmembrane G-protein-coupled receptors (GPCRs) on the surface of the cells of the thyroid.

- The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). Thyroid stimulating hormone (TSH), which is produced by the pituitary gland, acts to stimulate hormone production by the thyroid gland. The thyroid gland also makes the hormone calcitonin, which is involved in calcium metabolism and stimulating bone cells to add calcium to bone.

- Thyroid-Stimulating Hormone (TSH). Guide. A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.TSH causes the thyroid gland to make two hormones: triiodothyronine (T3) and thyroxine (T4). T3 and T4 help control your body's metabolism.Triiodothyronine (T3) and thyroxine (T4) are needed for normal growth of the brain, especially during the first 3 years of life. Find the cause of an underactive thyroid gland (hypothyroidism). 2  TSH levels can help determine whether hypothyroidism is due to a damaged thyroid gland or some other cause (such as a problem with the pituitary gland or the hypothalamus).

Thyroid-stimulating hormone Hormone levels. See also: Hypothalamic–pituitary–thyroid axis. TSH (with a half life of about an hour) stimulates the thyroid gland to secrete the hormone thyroxine (T4), which has only a slight effect on metabolism. T4 is converted to triiodothyronine (T3), which is the active hormone that stimulates metabolism. About 80% of this conversion is in the liver and other organs, and 20% in the thyroid itself. TSH is secreted throughout life but particularly reaches high levels during the periods of rapid growth and development.

Thyroid stimulating hormone thyrotrophic hormone or thyroid stimulating hormone (TSH) a hormone secreted by the anterior lobe of the PITUITARY GLAND which triggers the shedding of THYROXINE from the colloidal follicles of the THYROID GLAND into the bloodstream. Excess thyroxine inhibits the production of TSH - an example of a negative FEEDBACK MECHANISM.

This is an example of a negative feedback loop.

Hormone Function (main hormones) Calcitonin. Produced by the thyroid gland and decreases the blood calcium levels by stimulating calcium deposit in the bones (calcitonin keeps the bone in). The antagonist of the parathyroid hormone.ts release is stimulated by low blood glucose levels. It stimulates the liver, its primary target organ, to break down its glycogen stores to glucose and subsequently to release glucose to the blood.

- Thyroid-stimulating hormone (TSH) is produced by the adenohypophysis. It promotes development of the thyroid gland and maintenance of its normal function. TSH stimulates the thyroid to produce and release the thyroid hormones: T4 and T3 (hypothalamus-pituitary-thyroid axis). Measurement of TSH frequently is included with that of T4 and T3 in a laboratory panel to screen for and to evaluate thyroid disease.

Endocrine system Thyroid- stimulating hormone (TSH) stimulates the thyroid gland to produce hormones. Adrenocorticotrophic hormone (ACTH) stimulates production of hormones in the adrenal glands. the posterior or rear lobe of the pituitary gland secretes antidiuretic hormone (ADH), which regulates the balance of the water in the body.
