Understand the definition of tropic hormones: Tropic hormones are those that stimulate other endocrine glands to release hormones.
Identify the function of each hormone listed: Follicle-stimulating hormone (FSH) stimulates the gonads, Thyroid-stimulating hormone (TSH) stimulates the thyroid gland, and Adrenocorticotropic hormone (ACTH) stimulates the adrenal cortex.
Recognize that Growth hormone (GH) primarily acts on tissues to promote growth and does not stimulate another endocrine gland.
Compare the functions: FSH, TSH, and ACTH are all involved in stimulating other glands, while GH directly affects growth and metabolism.
Conclude that Growth hormone (GH) is not a tropic hormone because it does not target another endocrine gland to release hormones.
