Explanation:
The central nervous system can be thought of as the coordination and integration system within organisms. The CNS takes signals from the peripheral nervous system, processes them, then creates new signals to coordinate actions of different body systems. For instance, long-term and short-term metabolism and homeostasis are regulated through close interaction between the central nervous system and the endocrine system.
While the CNS is functionally made of neurons, other cell types such as glial cells play important supporting roles. Some cranial nerves, like the optic and olfactory nerves, are also considered to be a part of the central nervous system. All other nerves are part of the peripheral nervous system, but they still connect to the CNS. As such, the central nervous system is the coordinated processing center of the body.
