Stress Health and LifeStyle Flashcards
Stimulus based definitions
Something that disrupts your peace
Freaking out about something
Stress is how a person reacts to a stimulus
Response based definitions
Stress are the physiological experiences when dealing
with something
Bodily response that motivates you
FIght or flight
Sympathetic NS
- Epinephrine / norepinephrine
- pupils , heart rate increases, breathing increases, perspire, blood vessels constrict
Maintains homeostasis - optimal physiology for fight/flight
The Sympathetic Adrenal Medullary System
(SAM)
Stimulus -Thalamus - hypothalamus - adrenal gland (on kidney)
Adrenal gland
Middle part (medulla)
Secretes epinephrine (and norepinephrine)
Sympathetic arousal
Hypothalamic Pituitary Adrenal Axis
(HPA)
responsible for the neuroendocrine adaptation component of the stress response
Hypothalamic
Corticotropin releasing factor
Pituitary
Adrenocorticotropic H
Adrenal
Hypothalamic, Pituitary and Adrenal Axisis sent to the cortex (of adrenal gland)
Cortisol (HPA)
(main stress hormone - glucocorticoid)
+ blood sugar
Regulate blood pressure
Redirects blood flow
Suppresses immune function
slows down and suppresses production of lymphocytes (white blood cells)
Makes us more susceptible to colds and other sicknesses
Increases fat in the blood system
Hypothalamus
Adrenal medulla (SAME TIME) - via nervous system
- adrenaline
Pituitary glas (SAME TIME) - via blood stream - slower - endocrine system
- Adrenal cortex
- Cortisol
Arothema
Stress increases blood pressure
Hypertension
50% increase in having a heart attack
Chromosomes (response based definitions0
To repair split and make new ones
Tips of chromosomes - nonsense DNA
When split too much nonsense DNA is used up and you start cutting at important DNA
Increased aging, difficult repair work
Called telomeres
More stress = increased cortisol(inhibits telomerase = shorter telomeres
Telomerase builds back up
Lazarus’s appraisal model
Primary appraisal
Does this matter to me
1 YES - secondary appraisal
2 NO - no stress response
Secondair appraisal
Can i cope with it
1 YES - challenge
2 NO - stress
Stress - vasoconstriction (increased cardiac output)
Challenge - vasodialation(“”)
xStress definition
Individual perceives and responds to events that they appraise as overwhelming or threatening to their well-being
