What is the difference between the Sun and the other stars of the universe?

The brain is a part of the body which helps us, as well as animals, understand things. In the human body, the brain controls the use of language. The brain is the control center of the whole body. The brain is made up of a special type of cells. They are connected with each other and with the nerves in our body. In all animals, the brain is protected in some way. In humans, the skull (the bones of the head) protects their brains.

The brain is an organ in your body that controls how you think, learn, and feel. The brain also controls basic body actions, like breathing and heartbeat, which happen automatically. The brain uses nerves to tell the body what to do, for example, by telling our muscles to move or our heart to beat faster.

The right half of the brain controls the left side of the body, and vice versa (oppositely). The human brain is very large, compared to that of most other animals. The larger an animal is, the larger its brain will be. It is said that, Einsteinʼs brain weighed only 1,230 grams, which is less than the average adult male brain (about 1,400 grams). %2 of the bodyʼs weight is related to the brain, but it uses about %20 of its energy. It has about 50-100 billion nerve cells (also called neurons). The job of neurons is to receive and send information from and to the other parts of the body.
