1. Cell body(cyton) - which contain a large central nucleus & cytoplasm which Nissl's granules.
2. Dendrones - short processes arising from cell body and further branch inti dendrites.
3. Axon - single long, cylindrical processes of uniform diameter. It form fine branches terminally which are called symeptic terminals. They transmit nerve impulse. Axons are also called nerve fibers.
