Question

Which of the following is an INCORRECT statement about the stress response?

a. The anterior pituitary secretes adrenocorticotropic hormone (ACTH)
b. The adrenal medulla secretes cortisol
c. The hypothalamus secretes corticotropin-releasing hormone (CRH)
d. The posterior pituitary does not play a major role in the stress response

Answer 1

Answer:

b. The adrenal medulla secretes cortisol

Explanation:

Under stress conditions, anterior pituitary gland secretes adrenocorticotropic hormone (ACTH) which in turn stimulates secretion of glucocorticoids from the adrenal cortex. One of the main glucocorticoid hormone is cortisol.

The cells of the zona fasciculata of the adrenal cortex secrete cortisol. Cortisol increases the breakdown of proteins and lipids to facilitate the release of more energy to fight the stress conditions.
