Responds to danger and stress Happens automatically we don't think about it Physiological changes - heart rate, bp Adrenaline (fight or flight)
27
Describe the fight or flight response
Automatic decision we don't consider the two options, it's a personally trait or gut decision Generally one type or the other Acute stress response
28
What is an acute stress response?
Short lived stress response brought on by a stressor or situation Sometimes a good thing that it's automatic because there is not always time to think
29

System of ductless glands which secrete hormones directly in to the blood Allows hormones to be pumped around your body Interacts with nervous system Slow acting, long lasting changes to the body Regulated by hypothalamus and pituitary
44
What does the pituitary do and what are the two lobes?
Helps coordinate and release hormones | Anterior and posterior
45
What does the anterior lobe do?
Secretes hormones for growth: somatotrophic, gonadotrophic, and adrenocorticotropic hormone
46
What does the posterior lone do?
Produces oxytocin (controls contractions during labour), vasopressin (water absorption in kidneys)
47
What are the adrenal glands?
Two small glands located on top of the kidneys Each consists of adrenal medulla (epinephrine and norepinephrine) and adrenal cortex: stimulated by ACTH from the pituitary gland than releases hormones (steroids)
48
What is the adrenal medulla responsible for with the SNS under stress?
Secretion of catecholamines (fight and flight)
49
What is the adrenal cortex responsible for from the pituitary gland when under stress?
Body decreases energy expenditure in order to maintain energy for fight Makes decisions to deal with injuries after fight by inhibiting antibodies and saving energy
50
What are some disorders of the endocrine system?
``` Diabetes Osteoporosis Cushing's syndrome Menopause Obesity ```
51
What is obesity considered a disorder of the endocrine system?
Can often be lined to inappropriate levels of certain hormones regulating hunger Can also cause hormones to be released inappropriate once beginning
52
Describe the cardiovascular system

140
Define cognitive and internal cues
Cognitive: what you think about in response to an event
141
Define stress
A negative emotional experience accompanied by predictable biochemical, physiological, cognitive, and behavioural changes that are directed either toward altering the stressful event or accommodating to its effects Initiated or aggravated by exposure to a stessor
142
Define a stessor
An event, situation, experience, or trigger that causes stress Can include noise, overcrowding, large population, bad relationships, work-related activities, environmental factors
143
What are he direct physiological effects of stress?
Elevated lipids Elevated bp Decreased immunity Increased hormonal activity
144
What are the health habit effects of stress?

145
What are the health behaviour effects of stress?
Decreased compliance Increased delay in seeking care Obscured symptom profile Decreased likelihood of seeking case
146
What is the person-environment fit?
Perception of stress is determined by an individual's appraisal of resources Assessment of personal resources dictates degree of stress
147
What are some theories and models of stress?
Fight or flight: acute stress response General adaptation syndrome Tend and befriend
148
How did the general adaptation syndrome come about?
Selye exposed rats to various stressors Found all stressors produced the same physiological response Found that chronic stress can lead to wear and tear
149
What do stressors lead to according to the general adaptation syndrome?
Enlarged adrenal cortex Shrinking of thymus and lymph glands Ulceration of the stomach and duodenum
150
What are the three phases of the general adaptation syndrome?
Alarm: mobilize to meet the threat (resistance is low, similar to flight and flight) Resistance: cope through confrontation (resistance is high and balance is maintained until resistance is depleated) Exhaustion: deplete physical resources (resistance now drops below normal)
151
What are some limitations of the GAS?
Limited role of psychological factors Responses to stressors are uniform Stress is only evident in the presence of a stressor
152
What is the tend and befriend model?
Introduced social aspect to stress More prevalent in female Seeking physical contact during stress Increased levels of oxytocin
153
What is the psychological appraisal of stress?
Degree of stress is determined by psychological appraisal
154
What does the primary appraisal of stress determine?
Determines the meaning Is the event positive, neutral, or negative in its implications? If négative, to what extent is it presently harmful or threatening for the future and potentially challenging?
155
What is the secondary appraisal of stess?
Determine coping abilities and resources available | Are coping abilities and resources sufficient to overcome the harm, threat, or challenge posed by the event?
156
How does stress run?
Potential stressor causes primary and secondary appraisal which leads to stress
157
What is the physiology of stress?
Stress causes short and long term changes to health
158
What are the two physiological systems effects by stress?
Sympathetic-adrenomedullary (SAM) system | Hypothalamic-pituitary-adrenocorticol (HPA) axis
159
How does the SAM system function?
Harmful events are labelled by the cerebral cortex Info is transmitted to the hypothalamus Initiated earliest response to stress: sympathetic nervous system arousal (fight or flight) Stimulates the medulla of the adrenal glands Secretion of epinephrine and norepinephrine Leads to sympathetic arousal: bp, hr, sweating
160
How does the HPA acid work?
Activation of the hypothalamus releases corticotrophin-releasing factor (CRF) Stimulates pituitary gland to secrete adrenocorticotropic hormone (ACTH) Stimulates adrenal cortex to release cortisol Chronic activation of HPA acid alters cortisol levels
161
What does cortisol do?
Conserve stores of carbs, reduces inflammation Inhibits release of CRF Bring body back to steady-state
162
What is the problem with long term stress?
System was not designed for long term exposure of stress (allostérie load) Excessive discharge of cortisol, épi, NE can suppress immune system, increased bp and hr, arehythmias, neurochemical imbalance (mood disorders), lipids and fatty acids, sleep issues
163
What makes events stessful?
Degree of stress is dependent on assessment Negative events are more likely to cause stress Uncontrollable or unpredictable events Ambiguous events Level of individual tasks (overloaded) Central life vs peripheral stressors
164
Can you adapt to stress psychological?
Most can adapt to moderate stress Difficult to adapt to highly stressful events Does not cancel out any potential physiological changes
165
Can you adapt to stress physiologically?
Habituation and chronic strain exist Can accumulate across multiple organ systems Long term stressors can compromise immune function
166
Describe anticipated stressors
Can be just as stressful
