Its a surprisingly elaborate process. Here is a rough sketch of how it works:

Cells talk to each other by releasing chemicals that the other cells detect. This is very slow unless you want to talk to the cell right next to you, so it isn’t good for the nervous system.

To get around this neurons are very long and can quickly send a message down the length of their own bodies. When neurons get a chemical signal they use electricity to quickly signal their other end about it.

So the message is sent in long hops down the length of the neurons with a lot of little pauses to move chemically from one neuron to another.
