What does the anterior pituitary release to stimulate the thyroid gland?

• A. Adrenocorticotropic hormone
• B. Thyroid stimulating hormone
• C. Growth hormone
• D. Luteinizing hormone

Answer: (B)

The anterior pituitary releases thyroid-stimulating hormone (TSH) to stimulate the thyroid gland. TSH plays a crucial role in regulating thyroid function; it binds to receptors on the thyroid gland, leading to the production and release of thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). These thyroid hormones are essential for the regulation of metabolism, growth, and overall energy levels in the body. The link between the anterior pituitary and the thyroid gland is primarily part of the hypothalamic-pituitary-thyroid axis, where the hypothalamus produces thyrotropin-releasing hormone (TRH) to signal the anterior pituitary to secrete TSH. The release of TSH is vital for maintaining appropriate levels of these hormones in the bloodstream, ensuring that metabolic processes function optimally.
