Which statement is not associated with growth hormone?

• A. Somatotropin
• B. Secreted by posterior pituitary
• C. Hypersecretion results in acromegaly
• D. Affects lipid, carbohydrate, and protein metabolism

Answer: (B)

Growth hormone, also called somatotropin, is produced and secreted by the anterior pituitary gland. The posterior pituitary does not synthesize hormones; it releases vasopressin (ADH) and oxytocin that were made in the hypothalamus. So the statement claiming growth hormone is secreted by the posterior pituitary is not associated with growth hormone. Beyond its origin, GH promotes growth by stimulating IGF-1 production (primarily in the liver), supporting bone and tissue growth. It also has metabolic effects: it enhances lipolysis (affects fat metabolism), influences protein synthesis, and modulates carbohydrate metabolism (notably by affecting glucose use and hepatic glucose production). Hypersecretion of GH leads to acromegaly in adults (or gigantism in children), and somatotropin is simply another name for growth hormone, which aligns with the other true statements.
