Which of the Following Hormones Exerts Negative Feedback Control on the Secretion

Question

Which of the following hormones exerts negative feedback control on the secretion of ACTH?
A) PTH
B) Glucagon
C) Cortisol
D) Corticotrophin-releasing hormone

Accepted Answer

Cortisol exerts negative feedback control on the secretion of ACTH by the anterior pituitary gland. When cortisol levels are high, it signals the pituitary to decrease its secretion of ACTH, which then leads to a decrease in cortisol production by the adrenal gland. This negative feedback loop helps to maintain a balance of cortisol in the body.
