| The '''brain''' is the center of the [[nervous system]] in all vertebrate, and the majority of invertebrate, animals. Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates, the brain is located in the head, protected by the [[skull]] and close to the primary sensory apparatus of [[vision]], [[hearing]], balance, [[taste]], and [[smell]]. | | The '''brain''' is the center of the [[nervous system]] in all vertebrate, and the majority of invertebrate, animals.
