How Do Nerve Impulses Travel From One Neuron to Another?

WebWhen you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.”. Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision. WebThey are usually electrical signals that travel along the axon of the neuron. Neurons communicate with each other at specific points or junctions called synapses. These …
