The hypothalamic-pituitary-thyroid axis is a complex set of interactions between the hypothalamus, pituitary gland, and thyroid gland that regulates metabolism and energy balance in the body. This axis starts with the hypothalamus releasing thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to secrete thyroid-stimulating hormone (TSH), prompting the thyroid gland to produce thyroid hormones T3 (triiodothyronine) and T4 (thyroxine). These hormones play a crucial role in controlling metabolic processes and influencing growth, development, and overall homeostasis.
