Question

Quizplus · Accepted Answer

Growth hormone stimulates both hypertrophy (increase in cell size) and hyperplasia (increase in cell number) in various tissues, leading to overall growth and development. A is incorrect because growth hormone actually helps keep the epiphyseal plate open during childhood and adolescence, allowing for bone lengthening and growth. C is incorrect because growth hormone secretion is primarily stimulated by the hypothalamus releasing growth hormone-releasing hormone (GHRH) and inhibited by somatostatin, not by blood glucose levels. Finally, D is incorrect because while growth hormone plays a significant role in growth and development, other factors such as genetics, nutrition, and other endocrine factors also contribute.
