Question

Quizplus · Accepted Answer

The correct sequence of puberty hormone production starts with the hypothalamus in the brain, which releases gonadotropin-releasing hormone (GnRH), stimulating the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones then signal the gonads (ovaries or testes) to produce estrogen or testosterone. Additionally, the hypothalamus also controls the adrenal glands through the release of corticotrophin-releasing hormone (CRH), which stimulates the pituitary gland to release adrenocorticotropic hormone (ACTH), which signals the adrenal glands to produce cortisol. Therefore, the correct sequence is hypothalamus, pituitary, adrenal axis. Option A is the only choice that correctly identifies this sequence.
