cerebrum
what is the largest section of the brain?
brain stem
contains the medulla oblongata, pons and midbrain. functions in breathing, circulation, and digestion. sorts sensory info and decides where it goes and then sends it back down the spinal cord
diencephalon
sorts data and sends it where it needs to go for that particular information, maintains homeostasis. made up of the thalamus and hypothalamus
thalamus
makes up the diencephalon, on the top
hypothalamus
makes up the diencephalon, on the bottom
pituitary
hangs off the hypothalamus, releases hormones
corpus callosum
in between the right and left hemispheres, a bunch of neurons and nerves forming a brigade to send information between the two hemispheres
basal ganglia
below the cerebral cortex, made up of a bunch of neurons, controls motor control skills and excites certain motor functions
cerebral cortex

frontal lobe
executive lobe, boss of the brain, controls emotions
parietal lobe
controls sensation and reactions to the environment
occipital lobe
controls vision
temporal lobe
