The Human Brain Function The Human Brain Structure and functions The brain is the control center of the body. Its like a telephone operator who answers incoming calls and directs them to where they need to go. So think of the brain as an operator by sending messages from all over the body to their proper destination. The brain is one of the largest and most important organs of the human body. Weighing in at about three pounds, this organ has a wide range of responsibilities. From coordinating our movement to managing our emotions the brain does it all. The human brain is made up of billions of nerve cells, called neurons that share information with one another through a collection of biological and chemical signals. Each neuron is made up of a cell body, an axon, and many dendrites, all surrounded by a cell membrane. The nucleus, which contains genes composed of deoxyribonucleic acid (DNA), controls the cell's activities. The axon extends from the cell body and transmits messages to other neurons, sometimes over very long distances. Dendrites, which also branch out from the cell body, receive messages from the axons and specialized sense organs. Axons and dendrites collectively are called neurites.
