The brain is the control center of the body, responsible for processing sensory information, regulating bodily functions, and coordinating voluntary movements. The spinal cord is a long, thin, tubular structure that extends from the brainstem to the lower back. It serves as a conduit for transmitting nerve signals between the brain and the rest of the body.
