14
Q

Fight or flight

A

Endocrine system release adrenaline

Autonomic moves from resting parasympathetic state to aroused state

Aroused state = sympathetic

Parasympathetic NS reduces panic/ H.R

17
Q

Thyroid gland

A

Hormone- thyroxine increases heart rate

18
Q

Hormone definition

A

Chemical substance affecting any cells in body with the receptors

19
Q

Pituitary Gland

A

‘Master gland’

Controls hormones

20
Q

Adrenal gland

A

Affects cardiovascular system

Stress response- adrenaline

21
Q

Neurone types

A

sensory
relay
motor

22
Q

Sensory neurone

A

Carries messages from PNS to CNS

Long dendrites

Short Axon

23
Q

Relay Neuron

A

Connects all neurones together

Short dendrites and axons

24
Q

Motor Neuron

A

Connects CNS to effectors such as muscles or glands

Short dendrites

Long axons

25
Q

Parts of a neurone

A

Cell body - contain nucleus / DNA
Axon- long and carries impulses away
Myelin sheath- covers and protects axon Nodes of Ranvier- speed up transmission
Terminal Button- communicates with other neuones

26
Q

Summation

A

nerve cell receives inhibitory and excitatory neurotransmitter at the same time - net result of summation

more excitory - the cell fires at a high, positive rate

more inhibitory- not likely to fire / weak signal

27
Q

Excitation

A

Increases positive charge on post synaptic neurone, increases the likelihood of the neurone firing

E.G: adrenaline

28
Q

Inhibition

A

Increases negative charge on post synaptic neurone- decreases the likelihood of the cell firing

E.G: serotonin

29
Q

Motor area

A

Frontal lobe

Voluntary movements

Both sides of brain

30
Q

Somatosensory area

A

Parietal lobes

Sensory info from skin

pressure, pain, temperature

Both sides of brain

31
Q

Visual Area

A

Occipital lobe

receive and process visual info

Both sides of brain

32
Q

Auditory area

A

Temporal lobe

analyse and process acoustic info

both sides

33
Q

Broca’s area

A

language production

only on left side- lateralised

34
Q

Wernicks area

A

Language comprehension

Only left side

35
Q

Lateralisation

A

right controls left and left controls right

where areas are located

36
Q

Cerebral cortex

A

Protects the hemispheres

subdivisions

37
Q

What are the lobes of the brain

A

41
Q

occipital lobe

A

perception

42
Q

supporting evidence for localisation of function

A
