When a nerve signal, or impulse, reaches the ends of its axon, it has traveled as an action potential, or a pulse of electricity. However, there is no cellular continuity between one neuron and the next; there is a gap called synapse.

The chemical diffuses across the gap and makes the next neurone transmit an electrical signal.In order to see this content you need to have both Javascript enabled and Flash installed.
