Which system consists of the brain and spinal cord and coordinates information processing throughout the body?

• A. Peripheral Nervous System
• B. Central Nervous System
• C. Autonomic Nervous System
• D. Somatic Nervous System

Answer: (B)

The central nervous system serves as the body's information processing center, made up of the brain and spinal cord. The brain interprets sensory input, stores memories, and plans actions, while the spinal cord relays messages between the brain and the rest of the body and can coordinate simple reflexes. Together, they coordinate information processing throughout the body, which is why this system best fits the description. Other options describe parts of the nervous system that extend outside the brain and spinal cord and handle specific roles—like automatic bodily functions or voluntary movement—not the central coordination of information processing across the entire body.
