Which of the following structures is NOT part of the central nervous system?

• A. Cerebrum
• B. Cerebellum
• C. Spinal cord
• D. Peripheral nerves

Answer: (D)

The structure identified as not being part of the central nervous system is the peripheral nerves. The central nervous system (CNS) consists of the brain and spinal cord, which are responsible for processing and transmitting information throughout the body. The cerebrum is the largest part of the brain that controls higher brain functions, such as thought, action, and emotion. The cerebellum is located at the back of the brain and plays a critical role in motor control, coordination, and balance. The spinal cord serves as the main pathway for information connecting the brain to the peripheral nervous system. In contrast, peripheral nerves are part of the peripheral nervous system (PNS), which extends beyond the brain and spinal cord to innervate the rest of the body, including limbs and organs. The PNS is crucial for conveying sensory information to the CNS and carrying motor commands from the CNS to the muscles and glands. Thus, peripheral nerves are functionally distinct from the components of the central nervous system.
