Q

what does the sympathetic nervous system do in fight or flight

A

stimulates release of adrenaline

17
Q

what does the adrenal medulla do

A

release adrenaline

18
Q

what happens when in fight or flight

A

increased heart rate
sweating

blood vessels dialate

19
Q

3 types of neurons

A

sensory
relay
motor

20
Q

what do motor neurons do

A

-controls muscle movements
-when stimulated, they release neurotransmitters that bind to the receptors on muscles to trigger a response, leading

21
Q

what do relay neurons do

A

allow sensory and motor neurons to communicate

22
Q

what does the sensory neuron do

A

carry’s messages from the PNS to the CNS
- carry nerve impulses to the spinal cord and brain
- at the brain, they are translated into sensations

23
Q

localisation

A

the idea that specific parts of the brain have specific functions

24
Q

frontal lobe

A

motor area
controls voluntary movement

25
Q

parietal lobe

A

somatosensory area
where sensory information is detected from the skin

26
Q

temporal lobe

A

auditory area
processes speech based information

27
Q

occipital lobe

A

visual area
each eye sends bro from the right visual field to the left visual cortex and vice versa

28
Q

left frontal lobe

A

brocas area
language production

29
Q

left temporal lobe

A

wernickes area
language comprehension

30
Q

lateralisation

A

some neural functions ur cognitive processes are specialised to only one side or the brain

31
Q

where is language lateralised

A

left hemisphere
