Which nervous system component is responsible for processing information and coordinating activity, including the brain and spinal cord?

• A. Central Nervous System (CNS)
• B. Peripheral Nervous System (PNS)
• C. Enteric Nervous System
• D. Autonomic Nervous System

Answer: (A)

Processing information and coordinating activity are the main roles of the central nervous system. The brain handles complex processing like perception, memory, and decision-making, while the spinal cord not only relays signals but also coordinates many reflexes and integrates information from the body. The peripheral nervous system, by contrast, carries signals to and from the CNS. The enteric system mainly governs gut function, and the autonomic system regulates involuntary functions but relies on the CNS for directing overall activity. So, the central nervous system—comprising the brain and spinal cord—is the component responsible for processing information and coordinating activity.
