A decrease in cortisol triggers secretion of CRH (corticotropin-releasing hormone) by the hypothalamus which then stimulates secretion of ____ by the anterior pituitary.

A) cortisol
B) adrenocorticotropic hormone
C) thyroid stimulating hormone
D) antidiuretic hormone
E) aldosterone

Corticotropin-Releasing Hormone

A peptide hormone involved in the stress response, stimulating the release of ACTH from the pituitary gland.

Anterior Pituitary

The front portion of the pituitary gland, responsible for producing and releasing hormones that regulate various bodily functions.

Adrenocorticotropic Hormone

Adrenocorticotropic hormone (ACTH) is a peptide hormone produced by the anterior pituitary gland that stimulates the adrenal cortex to release cortisol and other steroid hormones.

  • Describe the regulatory feedback processes within the endocrine system.
  • Understand the distinct tasks performed by different endocrine glands and the hormones they release.

Final Answer :
B
Explanation :
A decrease in cortisol triggers a negative feedback loop in the HPA axis. This leads to an increase in CRH secretion by the hypothalamus, which subsequently stimulates secretion of adrenocorticotropic hormone (ACTH) by the anterior pituitary. ACTH then acts on the adrenal cortex to stimulate secretion of cortisol.
