stressor - (answer)a physical (external), chemical (internal), or psychological
(mental) factor resulting in tension of the body or mind
goal of stress response - (answer)maintain or re-gain homeostasis
4 normal stress responses of the body - (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 - (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
- 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 - (answer)- release Epinephrine,
similar function as Sympathetic activity
- sympathetic activity wanes quickly, E is more long lasting
Stress response: HPA axis - (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 - (answer)return to
normal state after stress
HPA axis not meant to sustain the response
Defining symptoms of PTSD - (answer)1. Intrusive memories - recurrent,
unwanted memories of traumatic event, nightmares, etc
2. Avoidance - avoiding thinking/talking about the event, avoiding reminders of it
3. Cognitive and mood disorder - negative thoughts about self, other people and
world, memory problems, lack of interest, detached, etc
