The brain is a complex organ that serves as the center of the nervous system. The brain exists in human, animals and trees, from microscopic size in viruses to the complex composition in human being. The brain is composed of the cerebrum, the brainstem and the cerebellum and followed by the spinal cord. This very specific organ is located inside the skull bones of the head. The shape and size of the brain varies greatly between species from more primitive ones to advanced brains.
