The three parts of a neurone are:
Dendrites which pick up the electrical impulses and pass them to the cell body.Cell body which contains the nucleus.Axon receives the impulse from the cell body and passes it on to the next neurone/ muscle via neurotransmitters crossing the gap (synapse) between them. Axons have a fatty layer (myelin sheath) around them to speed up transmission of impulses.Movement is always in one direction - dendrite to cell body to axon.Transmission of impulses in a neural pathway is sensory neurone to association/relay neurone to motor neurone.Hope this helps!
