- - - - Consists of cytoplasm and a nucleus
    - - Short extensions that strerch out of the cell body
      - Pick up impulses from the receptors and pass it to the cell body
    - - Long thread-like projection of the neuron
      - Has an insulating and protective sheath called "mylin sheath"
      - Mylin sheath is made by fats and proteins
      - Serves as a path for the impulses, in other to be passed to another neuron (and so on) through a juction called the synapse
- - - - The Brain
        
        Receives the delivered electrical impulses (Brain or Spinal Cord)
      - The Spinal Cord
  - - - Many nerves scatterd along the body
- - - - Take the message from the senses to the brain
    - - Carry messages from the brain to the body
  - - - Nucleus
        
        Is the cell body
      - Dendrites
        
        Take in the electric messages to cell bodies
        
        "entry"
      - Axon
        
        Take the message away from the cell bodies
        
        "exit"
- - - - Known as "The Little Brain"
      - Controls motion
      - Controls balance
      - Controls the ability to learn new things
    - - Biggest part of the brain
      - Controls senses
      - Controls imagination
      - Controls thoughts
    - - Known as "The Brain Stem"
      - Does involuntary actions (digestion,heartbeat,breathing)
