Stress Flashcards
Homeostasis
A state of balance,
RAAS System
Allostasis
-A process of restoring homeostasis in response to a stressor.
-Ability to successfully adapt to challenges
-Dynamic
Stress
-Physical, chemical, or emotional factor that results in tension of the body or mind.
-Real or Perceived: Modern Day perceived
-Perception is most important in determining response
Chronic Stress can Cause
Hypertension
High Blood Sugar
Depression
Stressors
-Agents that produce stress
-Can endanger homeostasis
-Positive or Negative
Risk Factors
-Conditions or Situations
-Increase likelihood of encountering stressor
Seyle’s General Adaptation Syndrome
Alarm
Resistance
Exhaustion
Alarm
-Fight or Flight Response
-Result of stress
-Hypothalamic-pituitary axis
-Glucocorticoids
Catecholamines (dopamine, norepinephrine, and epinephrine)
Catecholamines
(dopamine, norepinephrine, and epinephrine)
Parasympathetic
responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding
Sympathetic
“fight or flight”
Resistance or Adaptation
Activity of Neuroendocrine system
Returning body to Homeostasis
An allostatic state
Adaptation
-Biophsychosocial process
-Response to altered circumstances
-The way the body copes
Exhaustion
-Body can no longer return to homeostasis
-Allostatic Overload
-“Wear and Tear” may ensue
Habituation
-Diminishing Physical or Emotional Response
-After Repeated Exposure
Desensitization
-Delibrate habituation
-Therapy
Biofeedback
Visualization
Meditation
Endorphins
any of a group of hormones secreted within the brain and nervous system and having a number of physiological functions. They are peptides which activate the body’s opiate receptors, causing an analgesic effect.
Natural painkillers, mood boosters, activate opiate receptors.
Enkephalins
either of two compounds that occur naturally in the brain. They are peptides related to the endorphins, with similar physiological effects.
Glucocorticoids
-are a type of corticosteroid hormone that is very effective at reducing inflammation and suppressing the immune system. Inflammation is the way our immune system responds to harmful substances and trauma and is part of our healing process.
-Released from the adrenal cortex during stress.
