Psychosocial Coping Flashcards
what is stress?
Complex process that alters our psychological and physiological systems.
Actual or potential threat to homeostasis
May lead to physiological or psychological health issues
Part of life
Unique person-to-person
Eustress =
good stress
what is appraisal related to stress?
Initial reaction to POTENTIAL stress.
-Interpretation of situation and determination if it is a stressor.
what is coping?
Managing stress. Coping can mitigate or reduce the cause of stress or emotion it causes.
what is adaptation?
Outcome of coping. When a person SUCCESSFULLY adjusts or adapts to stress.
If a person is unable to adapt, pathological manifestations may occur.
How does the body maintain homeostasis?
KEEPING balance of: Blood pressure Glucose regulation Temperature regulation Acid-base balance All vital processes
what is allostasis?
Process of RESTORING homeostasis in response to stress.
Allostatic response occurs through physiological mediators:
Baroreceptors in aortic arch
Secretion of insulin
Hypothalamus
Respiratory response
individualized
What is the allostatic load?
= allostasis is sustained and homeostasis is not achieved. aka sustained allostatic state
-Cumulative burden of adaptation to stress
what can a sustained allostatic state lead to?
disease
what happens if stress is repetitive in relation to allostatic load?
If stress stimuli are excessive and repetitive, recovery to the original homeostatic levels may be incomplete
-As a result, the body adapts to anticipate the stress and creates “new” baseline for homeostasis.
example of new baseline due to repetitive allostatis?
An allostatic response may be increase in glucose level from a stressor, persistent allostasis will cause the body to adapt and allow a higher glucose level.
2 divisions of autonomic nervous system?
sympathetic
parasympathetic
what does sympathetic nervous system do?
Secretion of neurohormone norepinephrine and epinephrine. This can be excitatory or inhibitory.
Stressor–>pupil dilation, tachycardic (excitatory) but also slow down GI motility (inhibitory).
what does parasympthathic nervous system do?
- Secretion of acetylcholine.
- Following stress event, the PNS activates to return back to homeostasis.
- Example: Pupil constriction, reduce HR,…
systems involved in ANS?
Cardiovascular Respiratory GI Renal Endocrine
Neurotransmitters secreted by the sympathetic nervous system?
Norepinephrine and epinephrine
Excitatory actions?
Pupil dilation, increased heart rate, bronchial dilation, increased glucose
Inhibitory actions?
Decrease digestive function, inhibit insulin secretion, prevent urination
Major neurotransmitter for the parasympathetic nervous system?
Acetylcholine
most common glucocorticoid?
cortisol
