stressor - correct answer - a physical (external), chemical (internal), or
psychological (mental) factor resulting in tension of the body or mind
goal of stress response - correct answer - maintain or re-gain homeostasis
4 normal stress responses of the body - correct answer - 1. sympathetic
activation (within 2-3 seconds)
2. activation of adrenal medulla (20-30 seconds)
3. HPA axis activation (mins, hrs, or days)
4. cortisol neg feedback suppresses stress response (return to normal state
after stress)
Stress response: Sympathetic activation - correct answer - - HR increase,
vasoconstriction, sodium/water retention lead to higher BP and better blood
circulation
- Glycogenolysis, neoglucogenesis, lipolysis make nutrients more available
- Bronchial dilation results in more O2 intake
, Page |2
- Pupil dilation - more sensory info sent to brain
- Reduced digestion and bladder relaxation direct resources and attention
to stressor
- Increased bloodflow to skeletal muscle - Sympathetic innervation of blood
vessels of skeletal muscle is cholinergic in animals and is mediated by
E/beta2 receptors in both animals and humans but to a lesser degree
Stress response: Adrenal medulla activation - correct answer - - release
Epinephrine, similar function as Sympathetic activity
- sympathetic activity wanes quickly, E is more long lasting
Stress response: HPA axis - correct answer - - Glucocorticoids : breaking
down proteins, fatty acids, and glycogen; gluconeogenesis;
vasoconstriction; immunosuppression
- Minerolocorticoids : sodium/water retention to increase blood
volume/pressure
continue to support fight or flight
Stress response : Cortisol neg feedback to suppress response - correct
answer - return to normal state after stress
HPA axis not meant to sustain the response
Defining symptoms of PTSD - correct answer - 1. Intrusive memories -
recurrent, unwanted memories of traumatic event, nightmares, etc
