What is the stress response?
the body’s attempt to restore equilibrium
What activates the stress response?
both present stress and anticipatory stress
What is the Selye of the general adaption syndrome?
endocrinologist
What did the research with rats study?
the effects of ovarian extract
True or False. All rats did NOT receive injections
False (they all did)
- experimental group: injected with ovarian extract
-control group: injected with saline
What were the three findings of the research with rats?
- Ulcers
- enlarged adrenal glands
- shrunken immune tissues
What were the two important findings that were a result of the rat research?
- there is a similar set of responses to all type of stressors
- stress can make you sick
Why is it surprising that there is a similar set of responses to all type of stressors?
because our bodies typically respond differently to different stressors
True or False, GAS activates fight or flight response regardless of type of stressor
True
What are the 3 stages of GAS?
Stage 1: ALARM
Stage 2: Resistance
Stage 3: exhaustion
What occurs in the first stage of GAS?
ALARM: body mobilizes its resources: fight or flight
What does the alarm stage activate?
the sympathetic nervous system
When is the parasympathetic activated?
when at rest
When is the sympathetic nervous system activated?
during emergency
What happens to the body when the sympathetic system is activated?
- dilated pupils
-stimulates salivation
-accelerates heartbeat
-relaxes bronchi
-inhibits digestion
-stimulates glucose release by liver
-relaxes bladder
When is the amygdala reacting to fight or flight mode a good thing? When is it bad?
for acute physical threat but not for chronic psychological threat
When in fight or flight mode what happens to the amygdala?
detects threat leading to quick decision making, no time to think-must react
What is suppressed when fight or flight mode is activated?
the frontal lobe (decreases executive function)
When is the suppression of the frontal lobe in fight or flight a good thing?
its useful for test taking and other psychological stressors
What is the result of an overactive fight or flight response?
panic attacks
Is the amygdala overactive in this with anxiety?
yes
What happens in when a person is in fight mode?
-faces things head on
-prepare
-try to anticipate
-proactive
-listmakers
What happens when a person is in flight mode?
- AVOID
