What’s Primary Appraisal?
Access whether of not an event or situation is threatening. Ex, looking at a bill as threatening when you don’t have the money in the bank to cover it.
What’s Secondary Appraisal?
Determine whether or not we are in control and if we have resources to deal with the stressor. Ex, if you don’t get paid before the bill is due you may feel trapped or unable to cope.
What’s the HPA Axis?
Hypothalamus (activation to a threat), pituitary (secrete stress hormone, ACTH), and adrenal glands (release stress hormone). The is the center of stress response.
What’s General Adaptation Syndrome (G.A.S)?
Physical response is the same no matter what the source of stress. A three staged physiological stress response that appears regardless of the stressor that is encountered.
What are Chronis Stressors?
Sources of stress that occur continuously or repeatedly.
What’s Flight or Fight Response?
An emotional and physiological reaction to an emergency that increases readiness for action.
What Are the 3 Stages of G.A.S?
Alarm phase, resistance phase, exhaustion phase.
What is Alarm Phase?
In which the body rapidly mobilizes its resources to respond to the threat.
What’s Resistance Phase?
The body adapts to its high state of arousal as it tries to cope with the stressor. Continuing to draw on resources of fat and muscle, it shuts down unnecessary processes; menstruation stops; production of testosterone and sperm decreases.
What’s Exhaustion Phase?
The body’s resistance collapses. Many of the resistance-phase defenses cause gradual damage as they operate, leading to costs for the body that can include susceptibility to infection, tumor growth, aging, irreversible organ damage, or death.
What’s Telomeres?
Caps at the ends of chromosomes that prevent the chromosomes from sticking to each other.
What’s Telomerase?
An enzyme that rebuilds telomeres at the tips of chromosomes.
What’s the Immune System?
A complex response system that protects the body from bacteria, viruses and other foreign substances.
