What is stress?
A disturbance in a resins normal balanced state.
3 step physiological response to stress is… (Seyle) GAS
- Alarm - fight or flight
- Resistance/ adaptation - coping with the stressors
- Recovery or exhaustion
What are the differences between adaptive and maladaptive coping strategies?
- Adaptive is making healthy choices to negate effects of stress.
- Maladaptive are unhealthy choices that do not promote adaptation. Can relieve temporary anxiety but do not fix the problem. (Over-eating, over-working, over-sleeping.)
What is the difference between stressors, responses, and adaptation?
Stressors are the stimuli that one sees as a challenge and offsets equilibrium.
Responses are voluntary or involuntary actions that aim to restore equilibrium.
Adaptation is the change that takes place as a result of stress and coping.
Name and describe the first step of the General Adaptive Syndrome
- Alarm- fight or flight… Autonomic and endocrine systems effected.
Two phases of the Alarm Stage?
Shock- occurs when cerebrum receives stressor and activates endocrine and autonomic NS.
Counter shock- Changes produced in shock phase are reversed.
ACTH
Stims cortisol and aldosterone production
Cortisol
Spares glucose for brain.
Anti-inflammatory effect.
Uses fat and protein for E.
Aldosterone
Promotes fluid retention.
Kidneys absorb Na+.
Maintain blood volume and BP.
ADH
Increase tubule absorption.
Inches blood volume and BP.
Decreased urination.
Endorphins
Act like opiates to promote sense of well being and reduce pain.
TSH (Thyroid Stimulating Hormone)
Increases metabolism and fat conversion to energy for cell and muscle needs.
What does the Sympathetic NS do in the Alarm Stage?
Secretes adrenaline and norepinephrine from adrenal glands. This increases alertness.
Muscles contract and field of vision increases.
What is the second phase of the GAS.
Resistance– Coping with stressor.
Everything returns to normal. If that fails the third stage occurs.
What is the third stage of the GAS?
Exhaustion or Recovery.
The Local Adaptation Syndrome
Local response (tissue, body part, ect.)
What is the first part of the LAS?
Reflex pain response
Second Stage: Inflammatory Stages….
Vascular
Cellular
Exudate formation
Healing
What does hyperemia mean?
