Which part of the Nervous System consists of the Brain and Spinal Cord?

• A. Nervous System
• B. CNS
• C. Cardiac Control Centre
• D. Movement of blood

Answer: (B)

The central nervous system is the part that contains the brain and spinal cord. It acts as the body’s control center, processing information from the senses and coordinating responses by sending signals to muscles and glands. The nervous system as a whole includes the peripheral nervous system, which connects the brain and spinal cord to the rest of the body. A cardiac control centre is a specific brain region that helps regulate heart rate, not the entire nervous system, and movement of blood describes a physiological process rather than a structure of the nervous system. So, the brain and spinal cord belong to the central nervous system.
