Ch 37 potter Stress and coping Flashcards
is described as an actual or alleged hazard to the balance of homeostasis.
Stress
physical, chemical, or emotional factor that produces tension in the body or the mind
stress
are any physical, psychological, or social stimuli that are capable of producing stress and endangering homeostasis
Stressors
is how a person interprets the impact of the stressor
-personal evaluation of the meaning of the event to what is happening and a consideration of the resources on hand to help manage the stressor.
Appraisal
, was the first scientist to single out the physical side effects of stress.
Hans Selye, a Vienna-born endocrinologist
a three-stage set of physiological processes that prepare, or adapt, the body for danger so that an individual is more likely to survive when faced with a threat
general adaptation syndrome (GAS)//(developed by hans seyle
identified the three stages to the stress response as (1) initial alarm, (2) resistance as a person attempts to compensate for changes induced by the alarm stage, and (3) a state of exhaustion if the person cannot adapt successfully
3 stages of GAS //(developed by hans seyle
, the three-stage reaction to stress, describes how the body responds physiologically to stressors
general adaptation syndrome (GAS)
directly by a physical event or indirectly by a psychological event.
GAS is triggered either
which responds immediately to stress
neuroendocrine mechanism
body encounters a physical demand such as an injury, the
pituitary gland initiates the GAS
body will attempt to return to a state of balance, a process referred to as
allostasis
During the alarm stage the central nervous system is aroused, and body defenses are mobilized; this is the fight-or-flight response.
alarm stage
During the alarm stage the central nervous system is aroused, and body defenses are mobilized; this is the
fight-or-flight response.
rising hormone levels result in increased blood volume, blood glucose levels, epinephrine and norepinephrine, heart rate, blood flow to muscles, oxygen intake, and mental alertness.

alarm stage (fight-or-flight) effects
also contributes to the fight-or-flight response, and the body stabilizes and responds in an attempt to compensate for the changes induced by the alarm stage
resistance stage
. Hormone levels, heart rate, blood pressure, and cardiac output should return to normal, and the body tries to repair any damage that occurred
resistance stage impact
continuous stress causes progressive breakdown of compensatory mechanisms.
-This occurs when the body is no longer able to resist the effects of the stressor and has depleted the energy necessary to maintain adaptation. T
exhaustion stage
chronic arousal with the presence of powerful hormones causes excessive wear and tear on bodily organs and is called
allostatic load
long-term physiological problems such as chronic hypertension, depression, sleep deprivation, chronic fatigue syndrome, and autoimmune disorders
persistent allostatic load can cause
the level of personal control, presence of a social support system, and feelings of competence.
Personal characteristics that influence the response to a stressor include
Evaluating an event in terms of personal meaning is
primary appraisal.
, the process by which a person considers possible available coping strategies or resources, occurs at the same time
Secondary appraisal
, because feedback cues lead to reappraisals of the original perception, coping behaviors constantly change as individuals perceive new information.
