Which hormone is part of the FLAT acronym for anterior pituitary tropic hormones?

• A. FSH
• B. GH
• C. PRL
• D. MSH

Answer: (A)

Tropic hormones are those from the anterior pituitary that stimulate other endocrine glands to release their hormones. The FLAT group specifically includes Follicle-stimulating hormone, Luteinizing hormone, Adrenocorticotropic hormone, and Thyroid-stimulating hormone. These four act on ovaries/testes, adrenal cortex, and thyroid to drive hormone production. Among the options, Follicle-stimulating hormone is part of this group, so it is the correct choice. Growth hormone, prolactin, and melanocyte-stimulating hormone do not primarily stimulate another endocrine gland; they act on non-endocrine targets or have broad roles rather than gland-stimulating effects.
