cns

Question 1

2 main function of CNS

Answer 1

control of behaviour
regulation of psychological processes

Question 2

4 main area of brain

Answer 2

cerebrum
cerebellum
diancephalon
brain stem

Question 3

cerebrum

Answer 3

• further divided into 4 lobes
  (FPOT)
• split down in the middle into 2 halves called cerebral hemisphere
• each hemisphere is specialised for specific behaviour and the 2 halves communicate via the corpus callosum

Question 4

cerebellum

Answer 4

sits beneath cerebrum
- involves in contolling a persons motor skill and balance, coordinating muscles for precise movement

Question 5

brain stem

Answer 5

regulates automatic function that are essential for life

Question 6

spinal cord

Answer 6

it relays info between body and brain
allows brain to monitor and regukate bodily process

Question 7

diaencapharon

Answer 7

beneath cerebrum and above stem cell
within this area is thalamus and hyperthalamus

Question 8

thalamus

Answer 8

relay station of nerve impulse coming from senses routing them to appropriate part of the brain

Question 9

hyperthalamus

Answer 9

regulates body temp, hunger and thirst
controls of hormone from pituary gland

Question 10

function of PNS

Answer 10

relay nerve impulse from CNS to body
relay nerve from body to CNS

Question 11

somatic nerve impulse

Answer 11

these nerve has sensory and motor neuron

Question 12

reflex actions

Answer 12

in emergency situation, info wont go to CNS and it would make an automatic decisions

Question 13

autonomic nervous psychology

Answer 13

body carries out some actions without your conscious awareness such as breathing

Question 14

sympathetic nervous system

Answer 14

uses neurotransmitter which has stimulating effects

Question 15

exhibitory neurotransmitter

Answer 15

makes the post synaptic cell more likely to fire

Question 16

inhibitory neurotransmitter

Answer 16

an off switch
decreases the likelihood of neuron firing

Question 17

flight or fight

Answer 17

our bodies physiological response to an event that is perceived as an threatening or danger

Question 18

acute stressor

Answer 18

when your are faced with threat your amygdala is activated
amygdala assosiates sensory signals with emotions
amygdala sends a distress signal to hyperthalamus which communicates with the rest of the body through SNS ( sympathetic neuron system)

Question 19

chronic stress

Answer 19

ongoing

Question 20

SNS

Answer 20

send dignals to adrenal medulla, which responds by releasing the adrenaline to the bloodstream
