activation of the hpa axis allows the body to
Homework Answers
The HPA or (Hypothalamic-Pituitary-Adrenal) Axis is a unit of interaction between the hypothalamus, pituitary, and adrenal gland. It is our central stress management system and plays a key role in homeostasis. Apart from this it also allows the body to maintain metabolic, cardiovascular, immune, reproductive, and central nervous systems. The HPA activation leads to an increased level of cortisol in the body when we encounter any fear and decide to fight or flight.
When Corticotropin-Releasing Factor (CRF) binds with its receptor in the pituitary gland a hormone named Adrenocorticotropic Hormone (ACTH) is released, and ACTH binds the receptor to the adrenal cortex. Finally the adrenal cortex releases cortisol.

Discuss how glucocorticoid negative feedback suppresses the hypothalamic pituitary adrenal axis (HPA) for the suppression of the stress axis with a reference to experimental evidence. Your answer should include discussion of the receptor signaling pathways glucocorticoids signal through, the time course of action and the cellular functions which are altered following glucocorticoid receptor activation.
