Q

sympathetic nervous system

A

division of the autonomic nervous system responsible for the “fight or flight” response through the release of adrenaline
this system is known to increase heart rate, respiration, blood pressure, glucose release, and to dilate the pupils and decreases salivation/digestion

Q

James-Lange Theory of Emotion

A

idea that the physiological response to an event precedes the experience of emotion, and it is the interpretation of this physiological response that causes the emotion to be felt

25
stress
a physiological response to a threatening event or the perception of pressure
26
stessor
an event capable of causing physiological arousal
27
significant life change stressor
event that impacts a person in a drastic way, such as marriage, moving, job loss, having a child, or losing a loved one
28
Holmes and Rahe Stress Scale
test that gives a numerical value to the amount of stress that could be caused by 43 different significant lief changes used as an attempt to estimate the risk of stress-related illnesses
29
catastrophe stressor
an event that is threatening to nearly all people in a community, such as a natural disaster or war
30
daily hassle stressors
events that happen on a day to day basis that are appraised as irritable or generally negative, such as traffic, loud neighbors, bickering with a spouse, etc.
31
ambient stressors
anything that negatively impacts the population as a whole, such as pollution, noise, or overcrowding
32
stress reaction
the way in which a person copes with a threatening event or circumstance
33
appraisal
an evaluation of an event that determines the emotional and/or behavioral response
34
primary appraisal of stress
when an event is first evaluated as threatening or nonthreatening
35
secondary appraisal of stress
the evaluation of a person's ability to cope with a situation that has been deemed threatening this is when the person examines the harm that has already been experienced, the existing threat, and the probability that the threat can be overcome
36
fight or flight response
the body's reaction to a stressful event through sympathetic nervous system activation typically mediated by acetylcholine
37
adrenal gland
the endocrine gland located on top of the kidney that releases epinephrine/adrenaline and norepinephrine
38
adrenal medulla
the interior portion of the adrenal gland that is activated by the sympathetic nervous system and releases catecholamines (epinephrine and norepinephrine)
39
catecholamines
a class of hormones produced by the adrenal gland that includes epinephrine, norepinephrine, and dopamine
40
adrenal cortex
the exterior portion of the adrenal gland that releases hormones as part of the stress response, including aldosterone and cortisol
41
cortisol
a glucocorticoid hormone released by the adrenal cortex
42
glucocorticoids
``` a class of steroid hormones often released in response to stress (eg cortisol) ```
43
tend and befriend
a response to stress that revolves around creating and using social support
44
oxytocin
a hormone that contributes to social bonding, pair bonding, and childbirth
45
general adaptation syndrome
description of the body's response to stress that uses three stages: alarm, resistance, and exhaustion
46
alarm phase
initial reaction to stress that prepares the body for a fight or flight response heart rate and cortisol levels are elevated
47
resistance phase
period of time spent actively coping with a stressor | stress hormones including cortisol remain elevated, and breathing rate and blood pressure are elevated
48
exhaustion
after a prolonged period of stress, the body depletes its coping resources and enters this period of fatigue and decreased stress tolerance
49
hypertension
perpetually high blood pressure often caused by long-term stress-related elevations in blood pressure that increase muscle mass around blood vessels, which in turn increase rigidity, increasing blood pressure further indefinitely
50
vascular disease
a condition that affects blood vessels | caused by high blood pressure damaging the vessels, resulting in plaque buildup and narrowing of the vessels
51
coronary artery disease
type of vascular disease that occurs when there is plaque buildup in the coronary artery results in the heart not getting the nutrients it requires, which can cause a heart attack
52
glucagon
hormone that promotes the conversion of glycogen to glucose | it is released during the fight or flight response (among other times)
53
innate immune system
division of the immune system that is nonspecific and defends against pathogens using barriers, inflammation, and phagocytes this system can be upregulated with stress and potentially attack the body, or it can be repressed with chronic stress and fail to protect the body
54
depression
mood disorder characterized by a prolonged period of intense sadness and a loss of interest in previously enjoyed activities can be an effect of chronic stress
55
anhedonia
inability to feel pleasure | a classic symptom of depression
56
anterior cingulate
portion of the frontal cortex that is affected in depression and stops responding to serotonin, causing an increase in the perception of stressors
57
learned helplessness
a lost ability to identify and pursue coping mechanisms due to repeated inability to successfully cope with stressors
58
anxiety
excessive fear or worrying | can be an effect of chronic stress due to over-activation of the amygdala
59
addiction
some type of behavior that the sufferer feels compelled to perform, often impeding daily functioning often results when drug use is used as a coping mechanism for stress
60
coping with stress
act of putting conscious effort into reducing personal problems or conflicts or minimizing their effects success in this is related to the amount of perceived control the person feels they have over the situation, optimism, and social support
61
managing stress
many methods, including exercise, meditation, faith, and cognitive flexibility
