Question

Quizplus · Accepted Answer

Growth hormone stimulates the secretion of somatomedins, which in turn stimulate bone and tissue growth. Choice A is incorrect because growth hormone levels initially correlate with growth, but eventually plateau and do not continue to increase with continued growth throughout life. Choice C is incorrect because growth hormone actually stimulates osteoblast activity, leading to bone formation, not osteoclast activity, which is involved in bone resorption. Choice D is incorrect because excessive growth hormone in adults actually causes acromegaly, characterized by overgrowth of bones in the face, hands, and feet, not gigantism.
