Summary
This document explains the function and parts of neurons, including the cell body, dendrites, axon, and synapse. It describes neurons as messengers that transmit signals in the nervous system, allowing us to think, feel, and react to the world around us.

## NEURONS Neurons are the cells in your body that send and receive messages, allowing you to think, feel, move, and even breathe. Think of them like tiny messengers or "wires" that carry information. Here's a simple breakdown: 1. **What they do:** Neurons send signals (messages) between your brain and the rest of your body. For example, when you touch something hot, a neuron sends a message to your brain that it's hot, and your brain tells your hand to move away quickly. 2. **Parts of a neuron:** - **Cell body:** This is the "main hub" where the neuron's work is controlled. It keeps the neuron alive and healthy. - **Dendrites:** These are like "branches" that receive messages from other neurons. - **Axon:** This is the "long wire" that sends messages from the neuron to other neurons or muscles. - **Synapse:** This is the tiny gap between neurons where they send messages to each other using chemicals. 3. **How they work:** Neurons send electrical signals down their axon, and when they reach the synapse, they use chemicals to pass the message to the next neuron, like a relay race. In simple terms, neurons are the messengers that help you think, move, and react to the world around you!
