The brain, only weighing three pounds, is the control center of the human body. The brain receives and interprets information throughout the human body. The brain is able to receive information through our five senses; sight, smell, touch, taste, and hearing. Sometimes, the brain is able to receive them all at once. However, the brain doesn’t work alone. The nervous system is divided into central and peripheral systems. The central nervous system is made up of the brain and spinal cord. The peripheral system is made up of spinal nerves and cranial nerves that come down from the brain. The brain is divided into three major sections; the cerebrum, cerebellum, and brainstem. The cerebrum is the largest part of the brain and it is made up of the right and left hemisphere. The cerebrum performs like sensory information, such as interpreting touch, vision and hearing, as well speech, emotions, and learning. Next, the cerebellum, located under the cerebrum. The cerebellum is involved in muscle movements and balance. Finally, the brainstem, which includes the midbrain, pons, and medulla. The brainstem acts as a control center that connects both the cerebrum and cerebellum to the spinal cord. The brainstem performs many jobs such as, breathing, heartrate, body temperature, sleeping cycles, and many more. The brain has the thing called, right bran-left brain. The right and left hemisphere of the brain are joined together by corpus callosum that transmit messages from one side to the other. Each hemisphere controls the opposite side of the body. So the right controls the left, and the left controls the right. However, these two hemisphere do not share functions. The left hemisphere controls auditory information, understanding, and writing. While, the right hemisphere is involved in controlling our creativeness, musical skills, and artistic sides.
