This human brain anatomy diagram depicts the anatomy of the human brain. The brain is a miraculous three-pound organ that controls all bodily functions and interprets information from the outside world. The brain controls many things, including intelligence, creativity, emotion, and memory. The brain, which is protected within the skull, is made up of the cerebrum, cerebellum, and brainstem. The brain always receives the information from our five senses: sight, smell, touch, taste, and hearing, which are often used simultaneously. It puts the messages together in a way that makes sense to us and can store that information in our memory. The brain generally controls our thoughts, memory, and speech, the movement of our arms and legs, and the function of our bodies.
