The central nervous system is composed of the?

The central nervous system (CNS) is comprised of the brain and spinal cord. This structure is essential for processing information and coordinating actions throughout the body. The brain serves as the control center for thought, emotion, and sensory processing, while the spinal cord acts as the main pathway for transmitting signals between the brain and the rest of the body.

The other choices refer to components of the nervous system but do not accurately describe the CNS. Motor and sensory nerves connect the CNS to the peripheral nervous system, which is separate from the central nervous system's core components. Sensory nerves are responsible for transmitting sensory information to the brain, while motor nerves carry signals from the CNS to muscles, facilitating movement. Thus, focusing on the composition of the central nervous system specifically highlights the integral roles of the brain and spinal cord.
