Document Summary
Homeostasis is the process of maintaining a constant internal environment despite changing external conditions. Stress is the body"s response to a perceived threat to homeostasis. It is the body"s attempt to re-establish homeostasis. They are characterized as events or situations that trigger coping adjustments such as, exams or a rst date. Stress is a state of threat to this equilibrium, and adaptation to stress, or allostasis, confers a survival advantage. Successful adaptation requires not only the ability to respond to stress, but also the ability to control the stress response appropriately. Acute stress is a short-term type of stress that can be either positive (eustress) or distressing. This is the most common occurring type of stress. 2 stages of fight/flight response: sympathetic adrenomedullary system (sam) and hypothalamic pituitary adrenocortical axis (hpa). Short term fight/flight response (sam sympathetic adreno medullary) axis. The sam or short-term response is the primary system that is triggered within us in response to short- term threats.
