cerebral hemispheres Flashcards
frontal lobe function
motor
parietal lobe function
somatosensory
temporal lobe function
hearing, smell
occipital lobe function
vision
area 4
precentral gyrus
primary motor cortex
area 44,45
inf frontal gyrus
Broca’s area motor speech
area 3,1,2
primary sensory area
superior parietal lobule
sensory association area
awareness of contralateral half body
inferior parietal lobule
interface between somatosensory cortex and visual + audio
dom hemisphere = language functions
area 41,42
superior temporal gyrus
primary auditory cortex
auditory association areas
wernicke’s area
inferior surface temporal lobe
receive fibres from olfactory tract
conscious appreciation of smell
area 17
primary visual cortex
limbic lobe - what does it include
cingulate gyrus
hippocampus
parahippocampal gyrus
amygdalda
what does limbic lobe do
memory and emotional aspects of behaviour
broca’s aphasia
understand speech
misuse small words
aware of difficulties w speech
wernicke’s aphasia
meaningless words
can’t understand speech
doesn’t realise mistakes
commisural fibres
connect corresponding areas of 2 hemispheres
corpus callosum
association fibres
connect one part of cortex with another
can be long or short
projection fibres
run between cerebral cortex + various subcortical centres
internal capsule
made up of projection fibres passing to and from cerebral cortex
between thalamus and lentiform nucleus
internal capsule blood supply
middle cerebral artery
basal ganlia - what is it made up of
caudate nucleus
lentiform nucleus: putamen + globus pallidus
substantia nigra
what does basal ganglia do
helps regulate initiation and termination of movements
basal ganglia input regions
caudate nucleus
putamen
basal ganglia output regions
globus pallidus
substantia nigra
