The central nervous system (CNS) specifically consists of the brain and spinal cord. This definition is fundamental in neuroanatomy, as the CNS is responsible for processing and integrating information, coordinating body functions, and facilitating communication throughout the body.

The brain serves as the control center, interpreting sensory information, making decisions, and initiating motor commands. The spinal cord acts as a conduit for signals between the brain and the rest of the body. Together, they form the core structure that enables complex behaviors, reflexes, and higher cognitive functions.

In contrast, peripheral nerves, which connect the CNS to the limbs and organs, are part of the peripheral nervous system (PNS). The cranial nerves, although they originate in the brain, are also considered part of the peripheral nervous system, as they extend beyond the CNS. Understanding this distinction is crucial for grasping the overall organization and function of the nervous system.
