Q

Meninges

A

Pia= closest to brain tissue
Archnold
Dura

19
Q

the ventricular system

A

deep inside the brain
interconnecting ventricles
aquaduct for CSF

20
Q

hind brain

A

lowest and most primitive level/ develops first

cerebellum- motor coordination center

21
Q

mid brain

A

contains clusters of sensory + motor neurons
relays info between hind/fore brain
system of dopamine releasing neurons

22
Q

brain stem

A

supports vital function

23
Q

medulla

A

vital body functions

24
Q

pons

A

carries nerve impulses between higher and lower levels of the nervous system (sleep/arousal)

25
Q

cerebellum

A

motor coordination center

26
Q

reticular information

A

alerts higher centers of the brain that messages are coming = allows/blocks messages.

group fibres in the centre of the brain stem run between mid/hind brain (sleep/alertness)

27
Q

fore brain

A

most advanced proportion from an evolutionary standpoint

28
Q

cerebrum

A 
2 large hemispheres wrap around brain stem
divided into 4 lobes
occipital - vision
parietal- somatosensory
temporal- auditory
frontal - movement/ executive control
29
Q

cerebral cortex

A

covers cerebrum, grey matter unmyelinated convoluted +folded (sulci/gyri)

30
Q

cerebral hemispheres

A

right/left halves

31
Q

corpus callosum

A

connects hemispheres; neural bridge acts as a major communication link between 2 hemispheres and allows them to function as a single unit.

32
Q

grey and white matter

A

white matter = connection between cells (axons)

convoluted surface area (cortex)= grey matter

33
Q

primary cortex

A

primary visual cortex - occipital
primary auditory cortex- temporal
somatosensory cortex- parietal
motor cortex- frontal

34
Q

association cortex

A

many important mental functions including perception, language, thought

35
Q

pre frontal cortex

A

executive function= mental abilities that allow people to direct their behaviour in an adaptive fashion
goal setting, judgement, planning, impulse control.

36
Q

motor and sensory homunculi

A

sensation/ movement located close to each other

motor function is located frontally with the executive command region

37
Q

thalamus

A

2 lobed shaped attached at top of brain stem
messages received, processed and passed on (except smell)
integrates messages before passing into cerebral cortex

38
Q

hypothalamus

A

controls basic biological needs
controls autonomic NS
regulates bodily drives / endocrine system due to the influence of the pituitary gland
EMOTION/MOTIVATION

39
Q

hippocampus

A

involved in forming/retrieving memories

40
Q

amygdala

A

organises motivational and emotional response patterns

41
Q

language in the brain

A

left hemisphere

broca and wernicke

42
Q

broca area

A

speech production and language processing

43
Q

wernicke’s area

A

language development , comprehension of speech
