Full Answer

The cranium is the bony covering that protects the brain. The meninges surround the brain, and they consist of three layers of tissue, which are the pia mater, the arachnoid membrane and the dura mater, Atlanta Brain and Spine Care explains. The front area of the brain is called the cerebrum, the brain’s largest part. It plays a key role in controlling body temperature, movement, vision, hearing, touch, learning, judgment, problem solving and emotions.

In front of the cerebellum lies the brain stem, which serves as the body’s main control panel that transmits messages between the brain and the rest of the body, says Atlanta Brain and Spine Care. The brain stem controls essential body functions, such as consciousness, breathing, cardiac function and involuntary muscle movements. The back of the brain is known as the cerebellum, which is mainly a movement control center responsible for fine motor skills, voluntary muscle movements, and balance, posture and equilibrium maintenance.
