Multiple Choice

The secretion of GnRH (gonadotropin-releasing hormone) directly causes which of the following?

Release of insulin from the pancreas

Production of testosterone in the testes

Secretion of cortisol from the adrenal cortex

Release of FSH and LH from the anterior pituitary

Verified step by step guidance

Understand the role of GnRH: Gonadotropin-releasing hormone (GnRH) is secreted by the hypothalamus and plays a key role in regulating the reproductive system by stimulating the anterior pituitary gland.

Identify the target of GnRH: GnRH binds to receptors on the anterior pituitary gland, signaling it to release gonadotropins, specifically follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

Clarify the function of FSH and LH: FSH and LH are responsible for regulating reproductive processes, such as gamete production and hormone secretion in the gonads (testes and ovaries).

Eliminate incorrect options: Insulin secretion from the pancreas, testosterone production in the testes, and cortisol secretion from the adrenal cortex are not directly caused by GnRH. These processes are regulated by other hormones and mechanisms.

Conclude the correct answer: The secretion of GnRH directly causes the release of FSH and LH from the anterior pituitary gland, which is the correct answer to the problem.
