partietal lobe
occiptical lobe
temporal lobe
frontal lobe
what does the corpus collsium do?
Corpus Callosum connects the two hemispheres and facilitates communication between them
what dos the pons do
relays sensory information between the cerebellum and cerebrum. Controls arousal and regulates respiration
what does the medulla oblganta do?
Breathing, swallowing and heart rate
what does the forebrain consist of?
cerebrum and diencephalon
what inside the cerebrum?
cerebral cortex and basal nuclei
whats inside the dienephalon?
Thalmus and the hypothamulsus
what is the hypothalmsus in control off
regulates
body temp, hunger, thirst
Fatigue, anger and circadian
rhythms.
what does the thalmus control?
– regulates sleep/wakefulness,
consciousness, arousal
describe the cerebellum?
Responsible for motor coordination and balance
Ensures smooth movements of eyes and body
describe the cerebral cortex?

gyri
sulci
layers
lobes
what are the convolutions of the cerebral cortex
gyri
sulci
what is the cerebal cortex responsible for?
Perception of environment
Formulation of ideas
Experience of emotions
Recall of past events
what are functional areas of the cerebral cortex?
