General Adaption Syndrome

Question 1

what does stress do

Answer 1

have a negative impact physically and psychologically through the three stages of
alarm
resistance
exhaustion

Question 2

Seyle study

Answer 2

Did study on rats to elevate study

Question 3

Alarm phase

Answer 3

Body goes into the alarm and releases cortisol - which reduces pain. The next release is then adrenaline through the hypothalamus. This is known as the fight or flight. During this it decreased ur immune system.

Question 4

Resistance

Answer 4

More long term.
Produces a chemical response over a period of time which keeps a blood pressure elevated. Individual adapts to the stress and chemicals are constantly pumped round the body so the immune system is oppressed which can be damaging to cardiovascular system. Individual seems to cope

Question 5

Exhaustion

Answer 5

Body can no longer cope with the effects of the long term stress
So muscle tension occurs
the resources needed are becoming drained and the symptoms of alarm phase occurs
The immune system is weaknesses so a disease is more susceptible

Question 6

Acute Stress Reponse - SYMPATHOMEDULLARY pathway

Answer 6

aim - provide oxygen and glucose to skeletal muscles which helps us to generate fight or flight effects. Occurs in short term stressor

Question 7

What happens in acute stress reponse

Answer 7

The hypothalamus activates sympathetic nervous system. Which causes the adrenaline medulla to release adrenaline and noradrenaline. This causes the feeling of stress and fight or flight response. Once the stressor stops, the nervous system returns to a relaxed state

Question 8

Chronic stress response - hypothalamic pituitary adrenal system

Answer 8

This response occurs when a stressor is chronic, and the aim is to provide energy for a prolonged period of time. It uses hormones as a way of transmitting signals and chronic stress can lead to high levels of cortisol which effects health

Question 9

what occurs in chronic stress response

Answer 9

The hypothalamus releases hormones called CRF which triggers the phi tart gland to release hormones called ACTH into a blood stream. This causes the adrenal cortex to release cortisol.

Question 10

Weakness 1

Answer 10

model is biased towards male physiology. Females are less likely to fight or flight as it would leave off spring defence less.

Question 11

Weakness 2

Answer 11

doesn’t suggest to help with modern stressors, model is maladaptive

Question 12

weakness 3

Answer 12

model doesn’t consider freeze, may be more than two responses.

Question 13

strength

Answer 13

takes into account biologically as to why why experience stress and the symptoms which associate which increases understanding

Question 14

strength 2

Answer 14

studies to suggest it’s applicable - selye and general adaption syndrome

Question 15

strength 3

Answer 15

Science backs it up - reliable
