what does the stimulas do
its the event that evokes a specific function
what does the receptor do
recieves the information that a change has happend
what does the control centre do

what does the cerebrum do
its the largest part of the brain and divides the brain into two hemispere so they can communicate
what does the brainstem do
connects the brain to the spinal chord and controls basic life functions such as breathing and heart rate
what does the ocipital lobe do and where is it located
is located in the back of the brain and is responsible for visual processing
what part of the brain is responsible for co-ordinating voluntary movements and sperates the two sides
