The video tutorial explains the nervous system, comparing the CPU of a computer to the brain. It covers the central nervous system, including the brain's parts like the cerebrum, cerebellum, and medulla, and their functions. The peripheral nervous system's role in transmitting messages via neurons is discussed, highlighting how nerve impulses travel through axons and dendrites. The tutorial emphasizes the importance of the nervous system in responding to stimuli and coordinating body actions.
