Question

Quizplus · Accepted Answer

The central nervous system (CNS) consists of the brain and the spinal cord. The brain is the center of all cognitive functions, while the spinal cord is responsible for transmitting sensory information to the brain and motor information from the brain to the rest of the body. This makes option D the correct choice, as it includes both components of the CNS. Option A is incorrect because the peripheral nerves are part of the peripheral nervous system (PNS), and option B is incorrect because sensory and motor nerves are part of the PNS as well. Option C is partially correct in that interneurons are part of the CNS, but motor neurons are part of the PNS. Option E is incorrect because there is no such thing as the "cerebral" nervous system; the cerebrum is part of the brain, which is already included in option D.
