  3 parts units

  Cell body, Dendrites, Axon
• Cell body ● The central hub, containing the nucleus and

  keeping the neuron functioning.
• Dendrites ● Like tiny branches, they receive electrical

  signals (messages) from other neurons.
• Axon ● A long, slender fiber that transmits electrical

  signals (messages) to other neurons.
