Carries sensory information and controls movement of the skeletal muscles.
Somatic nervous system
What is referring to the fact that the neuron either fires completely or does not fire at all?
All or none principle
What is the Occipital Lobe?
Located at the rear and bottom of each cerebral hemisphere. Contains the visual centers of the brain.
