Anatomy of brain

?
primary somatosensory area location and function
- post central gyrus in each parietal lobe
- receives nerve impulses on touch, itch tickle, pain, proprioception, pressure and temperature
1 of 26
primary visual area
- posterior tip of occipital lobe
- visual perception
2 of 26
primary auditory area
- superior part of temporal lobe
- auditory perception
3 of 26
primary motor area
- pre central gyrus in frontal lobe
- controls voluntary muscle contractions
4 of 26
Broca's area
- frontal lobe near lateral cerebral sulcus
- production of speech
5 of 26
somatosensory association area
- posterior to primary somatosensory area
- recognising objects by feeling them and store these memories
6 of 26
visual association area
- occipital lobe
- recognising objects by looking at them and store these memories
7 of 26
auditory association area
- inferior and posterior to primary auditory area
- recognising sounds as speech, music or noise
8 of 26
wernicke's area
- left temporal and parietal lobes
- understanding the meaning of speech
9 of 26
gnostic area (common integrative area)
- bordered by association areas
- integrates lots of sensory inputs to one single thought
10 of 26
pre frontal cortex
- anterior frontal lobe
- personality, mood, memory, complex learning abilities, initiative and judgement
11 of 26
premotor area
- anterior to primary motor area
- memory bank for movements, make specific muscle groups contact in a specific sequence
12 of 26
pons
- superior to medulla in brainstem
- regulates breathing
13 of 26
medulla oblongata
- inferior part of brainstem
- involuntary reflexes
14 of 26
midbrain
- between pons and diencephalon
- vision, hearing, motor control, arousal, sleep/wake cycle, temp regulation
15 of 26
flocculonodular lobe
- inferior cerebellum
- equillibrium and balance
16 of 26
anterior an posterior lobes of cerebellum
- superior surface of cerebellum
- subconscious muscle movements
17 of 26
thalamus
- in dicencephalon
- emotions and memory (anterior nucleus)
- emotions, learning, memory, cognition (medial nucleus)
- expression of emotions (lateral group)
18 of 26
hypothalamus
- inferior to thalamus
- homeostasis
19 of 26
epithalamus
- superior and posterior to thalamus
- wakefulness
20 of 26
cerebral cortex
- outer rim of cerebrum
- contains billions of neurons (grey matter)
21 of 26
cerebral white matter
- myelinated axons
- association tracts (between gyri in same hemisphere)
- commissural tracts (connect gyri in opposite hemispheres)
- projection tracts (connect cerebrum to other parts of brain)
22 of 26
basal nuclei (location and functions)
- deep in each hemisphere
- initiate and terminate movements
- suppress unwanted movements
- regulate muscle tone
- cognition and behaviour
23 of 26
basal nuclei (names)
1. globus pallidus
2. putamen
3. caudate nucleus
24 of 26
cerebrospinal fluid
- in subarachnoid space between arachnoid mater and pia mater
- shock absorber
- optimal chemical environment for neuronal signalling
-exchange of nutrients and waste products
25 of 26
circle of willis
- created by internal carotid artery, vertebral artery and cerebral arteries
- supply blood to brain
