Is your brain a muscle?

The brain is not a muscle. While it does contain some muscle, it is primarily made of gray and white matter. The brain is a pale gray color and about the size of a small cauliflower. It has the texture of pate.

The brain is divided into four areas, which are known as the cerebrum, diencephalon, cerebellum and brain stem. Each area is responsible for different aspects of an individual’s personality and capabilities. The largest part of the brain is the cerebrum, which is found at the top of the brain. Its front part, or frontal lobe, is responsible for thought, emotion, speech and skilled movements.
