ANATOMY

Detailed explanation-1: -Regulation of thyroid hormone starts at the hypothalamus. 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-2: -TSH is a peptide hormone produced by the anterior pituitary.

Detailed explanation-3: -Your body has a complex system for controlling the level of thyroid hormones in your body. First, your hypothalamus (a part of your brain located on the undersurface of it) secretes thyroid-releasing hormone (TRH), which stimulates a part of your pituitary gland to secrete thyroid-stimulating hormone (TSH).

Detailed explanation-4: -What is the function of the pituitary gland? The main function of your pituitary gland is to produce and release several hormones that help carry out important bodily functions, including: Growth. Metabolism (how your body transforms and manages the energy from the food you eat).
