Changes in brain activity stimulate hypothalamic secretion of gonadotropin -releasing hormone (GnRH), which initiates puberty.

Question

Quizplus · Accepted Answer

The onset of puberty is triggered by changes in brain activity, specifically in the hypothalamus, which secretes gonadotropin-releasing hormone (GnRH). This hormone then stimulates the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), leading to the development of secondary sexual characteristics and reproductive capability.
