front and parietal are connected by the coronal suture
what are the four lobes of the cerebrum?
frontal, parietal, occipital, temporal (below)
Cerebrum function
memory, conscious/subconscious regulation of skeletal muscle contractions, intellectual functions
cerebellum function
coordinates complex somatic motor patterns
pons function
sensory information to cerebellum and thalamus
medulla oblongata function
sensory information to the thalamus
regulation of visceral functions
thalamus function
relay and process centres for sensory info
hypothalamus function
control emotions, autonomic functions and hormone production
midbrain function
process visual and auditory data, maintenance of consciousness and reflexive somatic motor responses
parietal lobe
sensory information input, body orientation, primary and secondary somatic area
occipital lobe
visual reception area and visual interpretation
temporal lobe
auditory reception expressed behaviour and receptive speech
