Week 5 Flashcards
What two adaptation forms maintain physiologic homeostasis?
-Local Adaptation system -General Adaptation syndrome
What is the Local Adaptation System (LAS) What are its two main parts?
-Localized adaptations in response to physical stressors. –Reflex pain response –Inflammatory response
What is the General Adaptation Syndrome? (GAS) Who is attributed with it?
The biochemical model of stress. How the mody adapts to stress that cant be controlled locally Hans Selye
What are the three stages of General Adaptation Syndrome
-Alarm reaction -Stage of resistance -Stage of exhaustion
What occurs during the Alarm reaction stage of GAS
-Stressor is perceived and defense mechanisms are activated -Fight or flight -Hormone levels rise -Shock and counter shock
What occurs during the Stage of resistance?
-Body attempts to adapt -Systems and vitals return to normal -Balance is achieved or Adaptation fails
What occurs if Adaptation fails during the stage of resistance?
Then the stage of Exhaustion occurs
What occurs during the stage of exhaustion?
The body enters rest and mobilizes defenses or it dies
What are the three major needs of psychological homeostasis?
-Love and belonging -Safety and Security -Self-esteem
What are the three main emotion responses to stress?
- Mind-Body interaction - Coping/defense mechanisms -Anxiety
What is the most common emotional reaction to stress?
Anxiety
What are the 4 levels of anxiety?
-Mild -Moderate -Severe -Panic
What happens to vitals during mild anxiety?
nothing
What happens to vitals during moderate anxiety?
They begin to slightly increase
What happens to vitals during severe anxiety?
-Tachycardia -Hyperventilation
