Appraisal
What happens when stress overwhelms existing coping mechanisms?
Patients lose emotional balance and crisis results

What is the arousal of the sympathetic nervous system which prepares a person for action?
Flight-or-fight response
What are the 3 structures in the body that control the response of the body to a stressor?
Medulla oblangata
Reticular formation
Pituitary glad
What are the physiological responses to a stressor?
Increased mental activity
Dilated Pupils
Bronchiolar dilation
Increased respiratory rate
Increased HR
Increased CO
Increased arterial blood pressure
Increased glucose
Increased fatty acids
Increased blood flow to skeletal muscles
What does the medulla oblangata do?
controls HR, blood pressure, and respirations
What does the reticular formation do?
continuously monitor the physiological status of the body through connections with sensory and motor tracts
What does the pituitary glad do?
produces hormones necessary for adaptation to stress (adrenocorticotropic, thyroid, gonadal, parathyroid hormones)
What are the three stages of the General Adaptation Syndrome (GAS)?
Alarm Reaction
Resistance Stage
Exhaustion Stage
How does a person progress from the alarm reaction stage to the resistance stage of the GAS?
the stressor poses an extreme threat to life or remains for a long time
What happens if the stress response during the resistance stage of the GAS is chronically activated?
a state of allostasis which causes excessive wear and tear on the person
What is primary appraisal?
evaluating an event for it’s personal meaning
