What is included in the definition of the Central Nervous System?

The definition of the Central Nervous System (CNS) includes the brain and spinal cord. The CNS is responsible for processing and transmitting information throughout the body. The brain acts as the control center, processing sensory data, and coordinating responses, while the spinal cord serves as the main pathway for information connecting the brain with the peripheral nervous system.

The brain and spinal cord work together to manage functions such as motor control, sensation, and many autonomic processes. While other components of the nervous system, such as peripheral nerves, play crucial roles in communication between the CNS and the rest of the body, they are not classified as part of the CNS itself. Therefore, the most accurate response regarding the components of the Central Nervous System is the brain and spinal cord.
