Answer #1

Solution:-

First of all we have to know that the role of CRF And ACTH

Corticotropin-releasing factor(CRF) act on Anterior pituitary gland during increase in emotions and stress.

After that Anterior Pituitary secrets ACTH which act on Adrenal cortex which help in secretion of cortisol hormone.

When cortisol level rise in blood after that the level of CRF and ACTH slows down.

So the solution is both CRF and ACTH secretion will decrease which is mention in option D

The hypothalamic-pituitary-adrenal axis includes corticotropin releasing hormone (CRH) from the hypothalamus, adrenocorticotropic hormone (ACTH) from the pituitary, and cortisol from the adrenal gland. In this system, CRH stimulates the release of ACTH, which stimulates the release of cortisol that exerts a negative feedback effect on both CRH and ACTH. Until only recently, there was no good tool to measure serum ACTH. Therefore, to evaluate whether pathologically high cortisol was related to ACTH, the “Dexamethasone suppression test” was invented. The elements...
