Nerve

Imagine your body is like a city and your nerves are like telephone wires. Just like telephone wires carry messages from one place to another, nerves carry messages between your brain and different parts of your body.

Now let's break down what a nerve looks like. A nerve is kind of like a long tube that is made up of lots of tiny fibers. These fibers are like the little wires inside a telephone wire. The fibers in a nerve are called neurons.

Neurons are special cells that are really good at sending messages. They have long, skinny branches called dendrites that reach out and connect to other neurons. When something happens in your body, like you stub your toe, the neurons in your toe send a message along their dendrites to other neurons in your spinal cord, which then sends the message up to your brain.

It's kind of like a game of telephone! Each neuron passes the message along until it reaches the brain, which is where the messages are processed and you feel the sensation of pain from stubbing your toe.

So, nerves are like telephone wires that carry messages between your brain and the rest of your body. Neurons are the little fibers inside nerves that are really good at sending messages!
