Sections/ lobes of the brain Flashcards
Frontal lobe - motor or sensory?
motor
pre central gyrus is motor or sensory?
motor
post central gyrus is motor or sensory?
sensory
inferior frontal gyrus
broca’s area of motor speech
pre frontal cortex
cognitive functions of higher order like:
intellect
planning
prediction
judgement
occipital lobe - main function/s
vision
parietal lobe main function?
somatosensory
perception/ making sense of things
post central gyrus is the
primary sensory area
temporal lobe main function/s
hearing
smell
wernicke’s area is crucial for
understanding the spoken word
on the medial surface of the occipital lobe is the
primary visual cortex
limbic lobe is the ….. area
functional
what is broaca’s area?
the motor speech area
aphasia
problems with speech due to damage to one or more speech areas in the brain
what lobe is broaca’s area in?
frontal
what lobe is wernicke’s area in?
temporal
main 3 contents of frontal lobe
broaca’s area
primary motor cortex
thinking area
main 1 content of occipital lobe
sight
main 3 contents of temporal lobe
hearing
smell
wernicke’s
main 1 content of parietal lobe
sensory
brainstem
vital centres (respiratory centre, cardio)
cerebellum
(autopilot)
balance and coordination
diencephalon
thalamus- sensory relay centre
body temperature
circadian rhythm
right middle cerebral artery supplies the
left body strength
left body sensation
left middle cerebral artery supplies the
right body strength and language
the right posterior artery supplies the perception of
left visual field
the left posterior artery supplies the perception of the
right visual field
area 4
primary motor cortex
pre-central gyrus
area 44/45
broaca’s area of motor speech
inferior frontal gyrus
area 3,1,2
primary sensory area
post central gyrus
area 41,42
wernicke’s area
primary auditory cortex
area 18
visual association cortex
area 17
primary visual cortex
limbic lobe is responsible for
memory and education
stroke affecting the arterial supply from the anterior cerebral artery would give what symptoms?
contra-lateral paralysis of foot/leg
contra-lateral sensory loss of foot/leg and impaired gait
stroke affecting the arterial supply from the middle cerebral artery would give what symptoms?
contra-laterial paralysis of face/ arm/ leg
contra-lateral sensory loss of face/ arm/ leg
contra-lateral homonymous hemianopia
gaze paralysis to the opposite side
posterior circulation problems would present with what symptoms?
coma
vertigo
N and V
ataxia (lack of voluntary coordination)
visual field deficits
