49
stress
occurs as a response to demands placed on one's body and/or mind
50
GAS: alarm reaction
Immediately when the body encounters a stressor an alarm is initiated and the fight-or-flight response begins. The person’s resistance is decreased so ideally the body transitions to the next phase before disease or death occur
51
General Adaptation Syndrome
Body's general response to stressors
52
GAS: resistance phase
the individual is still exposed to the stressor, but physiologic reserves are mobilized to increase the resistance to stress. This is the time of adaptation. It is during this stage that the factors that influence stress, such as attitude or coping abilities, will positively or negatively affect the resistance to the stressor. No physical signs or symptoms can be seen while an individual expends energy to adapt to a stressor, but the body will become strained over time.
53
GAS: Exhaustion phase
when all energy is expended, At the stage of exhaustion, it is common to become ill and even die if assistance from an outside source is not available (Fig. 8-2). This stage can often be reversed by external sources of adaptive energy, such as medication.
54
Three main systems in the physiologic response to stress:
nervous, immune, endocrine
55
Reticular Activating System (RAS)
which sends impulses contributing to alertness to the limbic system and to the cerebral cortex. When the RAS is stimulated, it increases its output of impulses, leading to wakefulness. Stress usually increases the degree of wakefulness and can lead to sleep disturbances.
56
coping
a person's cognitive and behavioral efforts to manage specific external or internal stressors that seem to exceed available resources
57
emotion-focused coping
involves managing the emotions that an individual feels when a stressful event occurs. Examples of emotion-focused coping include discussion of feelings with a friend or taking a hot bath.
58
problem-focused coping
attempts to find solutions to resolve the problems causing the stress. For example, setting priorities or collecting information and seeking advice would be considered problem-focused coping.
59
synovium
the inner layer of the articular capsule surrounding a freely movable joint. It is loosely attached to the external fibrous capsule and secretes a thick fluid to lubricate the joint and absorb shock.
