☆☆☆☆☆When an electrical signal, or impulse, reaches the end of an axon it triggers chemicals called transmitters. The electrical signals then become chemical ones as the transmitters cross the synapse, the gap between an axon and a dendrite. When they reach the dendrite of another neuron they spark a new electrical signal that then travels the length of that nerve cell. And it does this over and over until it reaches its destination.
