  1. 1. most common type of neuron which has one axon and multiple dendrites
  2. 2. excites a neuron triggering an electrical signal called an action potential
  3. 3. name of the nervous system in which instructions are carried by the motor division and taken to muscles that we can consciously control
  4. 4. output simply what the body is told to do as the result of all the information input and processing
  5. 5. parts of neurons that receive input and when received, an electrical signal is generated and transmitted toward the cell body
