Brain Control Center — Reading Comprehension

The brain is one of the most important organs in your body. It acts as your body’s control center. The brain sends and receives messages that help you move, think, feel, and remember things.

Your brain is made up of billions of special cells called neurons. These neurons use tiny electrical signals to communicate with each other. When you touch something hot, your neurons quickly send a message to your brain, and your brain tells your hand to move away. This process is part of your nervous system, which includes your brain, spinal cord, and nerves.

The largest part of your brain is called the cerebrum. The cerebrum helps you solve math problems, read stories, and talk with friends. Another part, the cerebellum, helps you balance and move smoothly. The brainstem controls basic actions like breathing and your heartbeat, even when you are asleep.

Your brain also lets you use your five senses: sight, hearing, smell, taste, and touch. For example, when you eat an apple, your brain helps you taste the sweetness and feel the crunch. If you play sports, your brain helps you catch a ball by quickly processing what your eyes see and telling your muscles what to do.

Sometimes, your brain reacts very fast without you even thinking. This is called a reflex. For example, when a doctor taps your knee, your leg kicks out automatically. Reflexes help protect your body from harm.
