ANATOMY

Detailed explanation-1: -TSH is a peptide hormone produced by the anterior pituitary. It consists of two chains: an alpha chain and a beta chain. It has a molecular mass of approximately 28, 000 Da. The composition is very similar to other glycoprotein hormones made by the anterior pituitary.

Detailed explanation-2: -The pituitary gland (located near the base of the brain) makes, stores, and releases thyroid-stimulating hormone (TSH). When TSH is secreted by the pituitary gland, it causes the thyroid gland to release more T3 and T4.

Detailed explanation-3: -The hypothalamus releases thyrotropin-releasing hormone (TRH) into the hypothalamic-hypophyseal portal system to the anterior pituitary gland. TRH stimulates thyrotropin cells in the anterior pituitary to the release of thyroid-stimulating hormone (TSH).

Detailed explanation-4: -Your pituitary gland makes the following hormones: Adrenocorticotropic hormone (ACTH or corticotropin). Antidiuretic hormone (ADH, or vasopressin). Follicle-stimulating hormone (FSH).
