Your brain is the command center for almost all of your activities—thinking, moving, and breathing. It coordinates the different parts of your body. Your brain holds more information right now than a million full sets of encyclopedias. Most of the information relates to your life, your body, your experiences, and what you've learned. Your brain looks like a large, gray, wrinkled walnut. It consists of over ten billion connected nerve cells. There are three main parts of the human brain. The largest and most important part is the cerebrum, which controls the senses, feelings, and thinking aspects of your life, as well as memory and speech. Most of the work you do in school involves this part of the brain. The cerebrum also controls the cerebellum, the part of the brain responsible for muscle use, coordination, and balance in the body. The brain stem controls functions such as breathing and heartbeat. Your brain has two sides called hemispheres. They control different actions and the opposite sides of the body. In right-handed people, the left side of the brain controls speech, language, and logical thought. The right side specializes in recognizing objects, controlling emotions, and creative ideas. In left-handed people, these roles are reversed. Protect your brain. You need it for a lifetime! 1. What is the best title of the reading?
