Question

Choose the correct answer from the alternatives given.
The blood cortisol level controls the secretion of:

• A. a releasing hormone from the hypothalamus
• B. adrenocorticotropic hormone (ACTH) from the anterior pituitary
• C. cortisol from the adrenal cortex.
• D. all of the above

Answer 1

Answer: (D)

all of the above

Adrenocorticotropic hormone or ACTH is secreted by the corticotropic cells of the anterior pituitary. It stimulates the flow of blood to the adrenal cortex, increases the concentration of cholesterol and steroids within the gland and increases the output of steroid hormones, especially cortisol. ACTH stimulates the synthesis and secretion of steroid hormones called glucocorticoids.

So the correct answer is all of the above.
