Describe how the hypothalamus and pituitary gland function in the negative feedback control of cortisol secretion when a person is under stress. Mention all relevant hormones involved in the process
What will be an ideal response?
Under stress, the hypothalamus secretes corticotropin-releasing hormone (CRH), which causes the pituitary gland to release adrenocorticotropic hormone (ACTH, also called corticotropin). The ACTH stimulates the adrenal cortex to secrete cortisol, which promotes metabolic changes that help resist stress. An increase in cortisol levels causes the hypothalamus to secrete less CRH, and this inhibition ultimately causes a decrease in the amount of cortisol secreted.
