(199 cards)
define stress
the physiological and psychological experience of significant life events, trauma, and chronic strain
what does the term general adaptation syndrome given by Selye means?
refer to the three distinct phases of physiological change that
occur in response to long-term stress: alarm, resistance, and exhaustion
what is PTSD
post traumatic stress diorder
a medical syndrome that includes symptoms of anxiety, sleeplessness, nightmares, and social
withdrawal.
define the 3 stages of general adaptation syndrome?
- General alarm reaction- body releases stress hormone, including cortisol.
- resistance- after a period of chronic stress-body adapts to ongoing threat and tries to return to its normal functions, glucose levels increase to sustain energy and BP increases.
3.Exhaustion- the body lacks energy and immunity. Blood sugar drops, causing low stress tolerance, exhaustion, illness, and collapse. Organs fail, leading to illness or death.
What are the two main physiological systems involved in the body’s stress response?
Autonomic nervous system and HPA(hypothalamic-pituitary-adrenal) axis
What is the role of cortisol in the stress response
It releases sugars into the blood to prepare the body to respond to threats
What happens to the immune system when exposed to chronic stress?
a) It becomes stronger and more resilient
b) It becomes less susceptible to diseases
c) It weakens, making the individual more susceptible to illnesses
d) It remains unaffected by stress
c) It weakens, making the individual more susceptible to illnesses
how does chronic stress contribute to heart disease?
a) By reducing cortisol levels in the body
b) By lowering blood pressure
c) By increasing blood flow through the arteries
d) By raising blood pressure and causing plaque buildup in arteries
d) By raising blood pressure and causing plaque buildup in arteries
Which statement best summarizes the long-term effects of stress on physical health?
a) Short-term stress can be beneficial, but chronic stress can lead to serious health problems.
b) Stress has minimal impact on physical health, primarily affecting mental well-being.
c) Chronic stress improves the body’s ability to heal and respond to threats.
d) Stress only affects individuals emotionally, with no significant physical consequences.
a) Short-term stress can be beneficial, but chronic stress can lead to serious health problems.
What physiological response occurs in the body as a result of stress?
a) Increase in activity in the parasympathetic division of the ANS
b) Suppression of cortisol production
c) Activation of the HPA axis
d) Decrease in blood pressure
c) Activation of the HPA axis
Which hormone is released by the adrenal glands in response to stress?
a) Insulin
b) Dopamine
c) Cortisol
d) Thyroxine
c) Cortisol
How does chronic stress contribute to heart disease?
a) By reducing blood pressure
b) By decreasing cardiac output
c) By increasing cortisol levels
d) By preventing plaque buildup in arteries
c) By increasing cortisol levels
What initiates the HPA response to stress?
a) Epinephrine
b) Cortisol
c) Releasing hormones from the hypothalamus
d) Norepinephrine
c) Releasing hormones from the hypothalamus
What hormone is released by the pituitary gland in response to stress?
a) Cortisol
b) Epinephrine
c) ACTH
d) Norepinephrine
c) ACTH
What role does cortisol play in the body’s response to stress?
a) It decreases blood sugar levels.
b) It inhibits the HPA axis.
c) It increases blood sugar levels.
d) It reduces the release of epinephrine.
c) It increases blood sugar levels.
Which gland secretes epinephrine and norepinephrine during the stress response?
a) Thyroid gland
b) Adrenal gland
c) Pituitary gland
d) Pancreas
b) Adrenal gland
name the effects caused by long term stress on the coronary system?
1.increases cardiac output (i.e., the
heart pumps more blood)
2. reduces the ability of the blood vessels to conduct blood through
the arteries
what do you mean by stressor?
ANY environmental stimulus that has the potential to produce stress
in what conditions can stressor increase illness?
- severely disrupt a person’s life
- are uncontrollable
- are chronic (i.e., lasting at least 6 months or more)
Who developed a measure of everyday life events that might lead to stress?
a) Thomas Holmes and Richard Rahe
b) Hans Selye
c) Glaser
d) Cacioppo
a) Thomas Holmes and Richard Rahe
define the term daily hassles
Our everyday interactions with the environment that are essentially negative, known as daily hassles,
What is the Social Readjustment Rating Scale (SRRS) used for?
a) To measure physical fitness
b) To assess emotional intelligence
c) To predict the likelihood of illness based on stressful life events
d) To evaluate cognitive abilities
c) To predict the likelihood of illness based on stressful life events
What did Glaser (1985) find regarding the immune system functioning of medical students?
a) Their immune system functioning improved during examination periods.
b) Their immune system functioning was not affected by examination periods.
c) Their immune system functioning decreased during examination periods.
d) Their immune system functioning remained constant during examination periods.
c) Their immune system functioning decreased during examination periods.
What did Cacioppo et al. (1998) find regarding the impact of minor stressors on the immune system?
a) Minor stressors had no effect on the immune system.
b) Minor stressors significantly improved immune system functioning.
c) Minor stressors compromised the immune system.
d) Minor stressors boosted the immune system.
c) Minor stressors compromised the immune system.
