The Body’s Control Center
Our brain sends messages to our body using special cells called neurons. Neurons carry signals between the brain and different parts of the body, telling them what to do. These signals travel through the spinal cord and then branch out through nerves to reach muscles, organs, and skin. This system works very fast, so fast that you can move your hand away from something hot in less than a second.
Electrical and Chemical Signals
Messages from the brain are sent as tiny electrical signals. When the signal reaches the end of a neuron, it passes through a small gap using chemicals called neurotransmitters. These chemicals tell the next cell what to do, and the message keeps moving until it reaches the right spot. This is how the brain controls movement, senses, and even things we don’t think about, like breathing and heartbeat.
