How Does a ‘Neuron’ Send Signals and Why Is It Important?

Neurons are like messengers in your brain. When you touch something hot, they send a message all the way to your brain so you can react, like pulling your hand back quickly. This happens because neurons use tiny electrical bursts called action potentials to talk to each other. It's like a light switch that turns on and off super fast, sending signals through wires (which are actually parts of the neuron) to let your body know what’s happening.
