homeostasis - correct answer--a state in which all symptoms are in balance at an ideal "set
point" despite alterations within the body
homeostatic response - correct answer--mechanistic, predictable series of orchestrated
internal events
allostasis - correct answer--addresses complexities and variable levels of activity necessary
to maintain or re-establish homeostasis
what are factors of stress? - correct answer--physical, chemical, biological, social, cultural
and emotional resulting in tension of the body or mind
alarm reaction - correct answer--fight or flight response due to stressful stimulus
allostatic state - correct answer--refers to the activity of various systems in attempting to
restore homeostasis
stage of resistance - correct answer--the activity of the nervous and endocrine systems in
returning the body to homeostasis
stage of exhaustion - correct answer--point where body can no longer return to homeostasis
(GAS) allostatic overload - correct answer--"cost" of body's organs and tissues for an
excessive or ineffectively regulated allostatic response
stressors - correct answer--agents or conditions that can produce stress and endanger
homeostasis.
catecholamines: norepinephrine and epinephrine (acute response) - correct answer--play an
integral role in allostasis
-sympathico-adrenal system response mediates the flight or fight response
adrenaocortical steroids: cortisol and aldosterone (chronic response) - correct
answer--critical to maintenance of homeostasis
-may synergize or antagonize effects of catecholamines
endorphins and enkephalon's: endogenous opioids (body's natural pain relievers) - correct
answer--raise pain threshold; produce sedation and euphoria
Sex hormones: estrogen, testosterone and dehydroepiandrosterone - correct answer--affect
stress responses, thus influencing allostasis--tend to have lower levels with chronic stress
individual stress responses - correct answer--change with time and circumstances
Ex: stress threshold over the years change and varies from person to person.
