The human brain is the control center for the nervous system. The brain is divided into two parts, the left and the right. They are almost symmetrical, but not quite. The left side of the brain controls the muscles on the right side. The right side of the brain controls the muscles on the left side of the body. The adult brain weighs about 3 pounds. The cerebrum makes 85 percent of the brain weight. The cerebral cortex is the largest part of the brain. The frontal lobes control self-control, planning, and logic. Some of the functions of the brain stem are to relay information from the brain to the body, and to control breathing, heart beat, and consciousness.
