Explanation:
Detailed explanation-1: -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: -The hypothalamic-pituitary axis regulates TSH release through hypothalamic neurons that secrete thyroid releasing hormone (TRH), a hormone that stimulates thyrotrophs in the anterior pituitary to secrete TSH.
Detailed explanation-3: -When the level of thyroid hormones (T3 & T4) drops too low, the pituitary gland produces Thyroid Stimulating Hormone (TSH) which stimulates the thyroid gland to produce more hormones.
