Lesson 5 - Fight or Flight Response Flashcards
1
Q
Sympathomedullary Pathway
A
- Sympathetic Nervous system is triggered by the hypothalamus
- Hypothalamus sends a signal to the adrenal medulla
- Leads to release of hormone called adrenaline into the bloodstream
2
Q
Adrenalines Effects
A
- Increase heart rate
- Constrict blood vessels
- Increase rate of blood flow
- Raise blood pressure
- Divert blood away from non-working organs
- Increase supply to skeletal muscles and brain
3
Q
Adrenaline
A
Prepares body for fight or flight response by increasing blood supply, therefore oxygen to skeletal muscles and brain for physical action and rapid response planning
4
Q
Parasympathetic Nervous System
A
- When the threat has passed, the stress response is dampened down
- Slows down the heartbeat and reduces blood pressure
- Digestion which is stopped when the SNS is active, restarts
5
Q
Evolutionary Support AO3
A
Fight or flight makes sense because it would have helped an individual to survive by fighting or fleeing from a threat
6
Q
Adrenal Glands Malfunction AO3
A
- Studies support that adrenaline is essential in preparing the body for stress
- People who have malfunctioning adrenal glands do not have a normal fight or flight response to stress
7
Q
Freeze (Gray 1968) AO3
A
- First response to stress is not fight or flight but freeze
- Involves person stopping, looking and listening and being hyper vigilant to danger
8
Q
Tend and Befriend (Taylor 2000) AO3
A
- Females tend and befriend in times of stress
- Referring to protection of offspring and seeking out social groups for mutual defence
- Women have the hormone oxytocin which means they are more likely to stay and protect their offspring
9

A
- Found that even males tend and befriend
