This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles. The brain is also cushioned and protected by cerebrospinal fluid. The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. It controls hunger and thirst and some of the most basic body functions, such as body temperature, blood pressure, and breathing. The brain stem connects the brain with the spinal cord.

The cerebellum, under the cerebrum at the back of the brain, controls balance and complex actions like walking and talking. This part of the brain also controls speech and emotions as well as reading, thinking, and learning. The right hemisphere controls the muscles on the left side of the body, and the left hemisphere controls the muscles on the right side of the body. The cerebrum uses information from our senses to tell us what's going on around us and tells our body how to respond.

It has two halves called the left and right cerebral hemispheres. The cerebrum, the largest part of the brain, fills most of the upper skull. The parts work together, but each has special functions. It has three major parts: the cerebrum, the cerebellum, and the brain stem. The brain is a soft, spongy mass of nerve cells and supportive tissue. The central nervous system is also involved with our senses-seeing, hearing, touching, tasting, and smelling as well as our emotions, thoughts, and memory. It controls the things we choose to do-like walk and talk-and the things our body does automatically-like breathe and digest food. This complex system is part of everything we do. Together, the brain and spinal cord form the central nervous system.
