Question

Cortisol is secreted by the adrenal cortex in response to stress

In addition to its function in a stress response, it functions in negative feedback by ______.

Options

• Inhibiting the hypothalamus, so that corticotropin releasing hormone (CRH) secretion is reduced.

• Inhibiting the anterior pituitary’s ability to respond io CRH by reducing the pituitary’s sensitivity to CRH.

• Both inhibiting the hypothalamus, so that corticotropin releasing hormone (CRH) secretion is reduced and Inhibiting the anterior pituitary’s ability to respond to CRH by reducing the pituitary’s sensitivity to CRH is correct.

• None of the above

Answer 1

Cortisol is secreted by the adrenal cortex in response to stress.

In addition to its function in a stress response, it functions in negative feedback by inhibiting the hypothalamus, so that corticotropin releasing hormone (CRH) secretion is reduced and inhibiting the anterior pituitary’s ability to respond to CRH by reducing the pituitary’s sensitivity to CRH.
