Which statement correctly describes Thyroid-stimulating hormone (TSH) function?

• A. Inhibits thyroid hormone production
• B. Stimulates adrenal gland
• C. Stimulates ovaries
• D. Stimulates secretion from thyroid gland

Answer: (D)

TSH’s job is to tell the thyroid to make and release its hormones. It’s released by the anterior pituitary in response to TRH from the hypothalamus, and when it binds to receptors on thyroid follicular cells, it stimulates the production and secretion of thyroid hormones (T3 and T4) and supports thyroid growth. This explains why the statement that TSH stimulates secretion from the thyroid gland is correct. It does not inhibit thyroid hormone production, nor does it act on the adrenal glands or ovaries.
