Hypothalamus secretes corticotropin-releasing hormone (CRH) to activate

the Sympathetic Nervous System which stimulates the adrenal medulla

(inner portion of the adrenal gland) to release the catecholamines.


Negative Feedback Loop - Returning to Homeostasis from Fight-or-Flight

(occurs simultaneously)


Hypothalamus secretes CRH stimulate the anterior pituitary gland to

release adrenocorticotropic hormone (ACTH). ACTH then causes the

adrenal cortex (outer portion of the adrenal gland) to release

corticosteroids.


Resistance/Adaptive Phase - Answer✔️✔️-Allostasis is essentially the

activation of these stress responses to evoke changes that return the

organism to homeostasis.


Exhaustion - Answer✔️✔️-If the alarm stage were to persist (homeostasis

doesn't return), the body would suffer undue wear and tear and become

subject to permanent damage and even death.


Catecholamines - Answer✔️✔️-Epinephrine and Norepinephrines
