The central nervous system (CNS) is composed of the:

• A. Meninges and spinal cord
• B. Cerebrum and meninges
• C. Brain and spinal cord
• D. Cerebellum and brain

Answer: (C)

The central nervous system (CNS) is primarily made up of the brain and spinal cord. These two components work together to process and transmit information throughout the body. The brain is responsible for higher cognitive functions, sensory processing, and coordinating motor activities, while the spinal cord serves as a critical pathway for transmitting signals between the brain and the rest of the body. Meninges, which cover the brain and spinal cord, play a protective role but are not considered part of the CNS itself. Similarly, while the cerebrum and cerebellum are parts of the brain, focusing solely on those components overlooks the spinal cord, which is essential for the function of the CNS. Therefore, identifying the CNS solely as the brain and spinal cord provides a clear and accurate representation of its structure and function.
