Sergeu [11.5K]
<span>The correct answer is c. ​hypothalamus to pituitary gland to adrenal glands.
</span>
When it comes to stress, hypothalamus-pituitary-adrenal axis (HPA) is responsible for stress response. Hypothalamus releases corticotropin-releasing hormone (CRH) which binds to its receptors on the anterior pituitary gland. As a result, adrenocorticotropic hormone (ACTH) is released and it stimulates the release of cortisol from the adrenal gland. At a certain levels of cortisol, this steroid hormone exerts negative feedback to the hypothalamic release of CRH.
