Electrical impulses are carried along the axon of a neurone Neurones have branched endings (dendrites) so they can connect with lots of other neurones Some axons are also surrounded by a fatty sheath. This acts as an electrical insulator, speeding up the electrical impulse. Neurones are long, which speeds up the impulse as connecting with another neurone slows down the impulse, so one long neurone is much quicker than lots of short ones joined together. The connection between two neurones is called a synapse. It is a very small gap.
