Flashcards in 3.3.2 Adrenaline & Acute stress Deck (30):
1

(SAM) what does SAM stand for?

sympathomedullary pathway

2

(SAM) when a stressor is perceived an immediate physical response is triggered through which branch of the ANS?

sympathetic

3

(SAM) activation of the sympathetic branch of the ANS triggers what response?

fight or flight

4

(SAM) 1. a stressor is perceived activating what?

the hypothalamus

5

(SAM) 2. what pathway is activated?

the SAM pathway

6

(SAM) 3. which branch of the ANS is activated?

the sympathetic

7

(SAM) 4. activation of the sympathetic branch stimulates what?

the adrenal medulla

8

(SAM) 5. the adrenal medulla secretes what?

adrenaline and noradrenaline into the bloodstream

9

(SAM) 6. what do adrenaline and noradrenaline do?

prepare the body for fight or flight

10

(f or f) in the fight or flight response why does saliva production decrease?

focus on essential functions

11

(f or f) in the fight or flight response why do pupils dilate?

to allow in as much light as possible for improved vision

12

(f or f) in the fight or flight response why does quick, deep breathing occur?

to get more oxygen to muscles in preparation for fight or flight

13

(f or f) in the fight or flight response why do blood vessels close to the skin constrict?

to direct blood to where it is necessary - essential organs

14

(f or f) in the fight or flight response why does the heart beat faster?

to pump oxygenated blood to respiring muscle tissue quickly

15

(f or f) in the fight or flight response why does the output of digestive enzymes in the stomach decrease?

to focus on essential functions

16

(f or f) in the fight or flight response why does food movement slow?

to focus on essential functions

17

(f or f) in the fight or flight response why do major blood vessels dilate?

to pump more oxygenated blood to muscles quickly

18

(freeze) according to Barlow (2002) when might a freeze reaction occur?

in situations when running or fighting back would be ineffective

19

(freeze) give examples of where the freeze reaction is seen:

animals that play dead when faced with a predator
human victims of violent crime sometimes report being unable to move

20

(freeze) Koutsikou et al suggest the freeze reaction may have what?

a biological basis

21

(freeze) Koutsikou et al researched rats and identified a pathway linking what?

the PAG and the pyramis of the cerebellum

22

(freeze) what is the PAG (periaqueductal grey) responsible for?

how humans and animals perceive danger

23

(freeze) what does the pyramis do?

causes the body to freeze in place

24

(evolution) what is the EEA?

environment of evolutionary adaptiveness

25

(evolution) what are adaptive behaviours?

behaviours which helped aid survival and reproduction via natural selection

26

(evolution) what happens to adaptive behaviours?

passed on

27

(evolution) what is the fight or flight reaction?

an adaptive behaviour it would have helped survival and reproduction

28

(evolution) why might the fight or flight reaction not be adaptive today?

we have more psychological stressors than physical stressors - physical response is outdated

29

(heart) what has a direct effect on the heart?

high levels of adrenaline and noradrenaline

30

(heart) high levels of adrenaline and noradrenaline are linked to what?

cardiovascular disorders
heart attacks
stroked
high blood pressure
