Document Summary
Walter cannon noted that the physical responses to stressors was rather general even though that stressors can come from a variety of sources like biological, cognitive, or social. Fight or flight response: a set of physiological changes that occur in response to psychological or physical threats. Hans selye looked past the fight or flight response and found that there is a larger pattern during the stress response. Gas (general adaptation syndrome): a theory of stress response involving stages of alarm, resistance, and exhaustion. Alarm- recognition of the stressor and the physiological responses that come with it (increase in blood pressure, etc. , ) Resistance- an individual using his or her physical and mental resources to respond to the stressor in a appropriate way. Exhaustion- when the stressful experience depletes all your physical resources and the physiological response declines. Hypothalamus stimulates the sympathetic nervous system causing the adrenal glands, specifically the adrenal medulla, to release epinephrine and norepinephrine.
