Stress - Bodily Response To Stress

Question 0

What is the fast system called?

Answer 0

Nervous system

Question 1

What is the slow system called?

Answer 1

Endocrine system

Question 2

What are the 2 branches of the nervous system?

Answer 2

Peripheral nervous system

Central nervous system

Question 3

Explain the central nervous system?

Answer 3

It contains the brain and the spinal cord.

Question 4

Explain the endocrine system?

Answer 4

It is the system that is made up of all the glands and muscles that control the hormones within the body

Question 5

Explain the peripheral nervous system?

Answer 5

It goes into the autonomic nervous system which has 2 branches…
The sympathetic branch - arousal
Parasympathetic branch - calm

Question 6

How does the nervous system convey its messages?

Answer 6

Ver quickly through electrical signals passing along neurones, relying on chemicals (neurochemicals) in the synapses between the neurones.

Question 7

What does the peripheral nervous system contain?

Answer 7

Sensory and motor pathways

Controlling responses such as muscle movement

Question 8

What is the autonomic nervous system?

Answer 8

It connects the various glands e.g. The adrenal medulla
This separates into 2 branches
When there is dominance in the sympathetic - bodily arousal - increase in heart rate and blood pressure
When there is a dominance in the parasympathetic branch - bodily calm

Question 9

True or false? The endocrine glands secrete hormones straight into the bloodstream?

Answer 9

True

Question 10

True of false? The nervous system influences behaviour more quickly then the endocrine system?

Answer 10

True

Question 11

What is the fight or flight response?

Answer 11

Has evolved to enable us to deal with threats - triggered by events that we find physically or psychologically threatening

Question 12

What are the 2 systems I need to know?

Answer 12

Sympathomedullary Pathway - SAM

Pituitary-adrenal System - PAS

Question 13

What does SAM involve?

Answer 13

The autonomic nervous system

Hormones, adrenaline and nonadrenaline

Question 14

What does PAS involve?

Answer 14

Only hormonal

Question 15

How does SAM work?

Answer 15

A stressor acts upon the hypothalamus
Activating the sympathetic branch of the ANS
Stimulating the Adrenal Medulla
Which releases the adrenaline and non adrenaline
Increasing BP / HR and sweat gland activity

Question 16

How does PAS work?

Answer 16

Stressor acts upon the hypothalamus
Activating the Pituitary gland
Which releases ACTH that stimulates the Adrenal Cortex
Which releases Corticosteroids e.g Cortisol
They can convert fat and protein stored in the liver into energy and over time suppress the immune system

Question 17

Name the hormones that the glands produce?

Answer 17

Thyroid gland - thyroxin
Pancreas - insulin
Testes - testosterone
Ovaries - estrogen and progesterone
Adrenal glands - adrenaline and nonadrenaline

Question 18

What are some possible explanations for the correlation between stress and illness?

Answer 18

Stress weakens the immune system
Stress response causes fatty acids in the blood and furring the arteries resulting in a heart attack

Illness meaning that they cannot cope with work, difficulties in relationships leading to stress
Inherited gene meaning they get both stress and illness

Illness causing stress and stress causing illness

Question 20

Explain tend or befreind?

Answer 20

More likely to be caused by there being attachment with the thing meaning that there is no fight or flight response
