Final answer:
The negative feedback by a steroid at all levels of the hypothalamus-anterior pituitary-adrenal cortex stress response implies that each of these components has receptors for glucocorticoids.
Step-by-step explanation:
The negative feedback by a steroid at all levels of the hypothalamus-anterior pituitary-adrenal cortex stress response implies that each of these components has receptors for glucocorticoids.
Glucocorticoids are steroid hormones, such as cortisol, that are secreted by the adrenal cortex.
When the levels of glucocorticoids in the blood rise, they provide negative feedback to the hypothalamus and pituitary gland, inhibiting the release of corticotropin-releasing hormone (CRH) from the hypothalamus and adrenocorticotropic hormone (ACTH) from the pituitary gland.
