EVERYDAY SCIENCE

Detailed explanation-1: -The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you’re less aware of-like the beating of your heart and the digestion of your food. Think of the brain as a central computer that controls all the body’s functions.

Detailed explanation-2: -Neurons send and receive electrical signals to communicate with each other in the nervous system and with other types of cells in the body, particularly muscles. At one end, neurons have branch-like projections called dendrites that allow them to receive signals.

Detailed explanation-3: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.

Detailed explanation-4: -The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. But the brain can do much more than a machine can: humans think and experience emotions with their brain, and it is the root of human intelligence.
