Thyroid-stimulating hormone (also known as thyrotropin, thyrotropic hormone, or abbreviated 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. [1]
Thyroid-stimulating hormone (TSH) released from the anterior pituitary (also known as the adenohypophysis) binds the TSH receptor (a G s protein-coupled receptor) on the basolateral membrane of the cell and stimulates the endocytosis of the colloid. The endocytosed vesicles fuse with the lysosomes of the follicular cell.
Thyroid-stimulating hormone, or thyrotropin, triggers the release of thyroxine (T 4) and triiodothyronine (T 3) from the thyroid gland. [1] Thyrotropes comprise around 5% of the anterior pituitary lobe cells. [2] H&E staining of the pituitary gland. Thyrotrophs appear basophilic.
“Selenium is an essential mineral that acts as an antioxidant and helps regulate thyroid hormone metabolism, potentially reducing thyroid antibodies and thyroid stimulating hormone (TSH) levels ...
The thyroid hormones influence the metabolic rate and protein synthesis and growth and development in children. Calcitonin plays a role in calcium homeostasis. [1] Secretion of the two thyroid hormones is regulated by thyroid-stimulating hormone (TSH), which is secreted from the anterior pituitary gland.

Thyroid stimulating hormone (TSH) is produced by the pituitary gland, another hormone-producing organ in the head. This in turn causes the thyroid to produce T3 and T4, which play a role in the ...
The pituitary gland secretes thyrotropin (TSH; Thyroid Stimulating Hormone) that stimulates the thyroid to secrete thyroxine (T4) and, to a lesser degree, triiodothyronine (T3). The major portion of T3, however, is produced in peripheral organs, e.g. liver, adipose tissue, glia and skeletal muscle by deiodination from circulating T4.
