Nervous System

The video explains the nervous system's role in processing information and controlling body functions. It is divided into the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which connects the rest of the body. The brain processes sensory information and sends signals to respond, such as moving muscles. Reflexes are quick responses to stimuli, involving the spinal cord for immediate action. Overall, the nervous system is a vital communication center for interpreting and responding to internal and external signals.
