2.83 recall that the central nervous system consists of the brain and spinal cord and is linked to sense organs by nerves

The central nervous system consists of the brain and the spinal cord.
The central nervous system or CNS is a intricate network of nerve cells and nerve fibers throughout the body. Its function is to interpret, store, and respond to information received from inside the body and outside the body. The CNS is responsible for processing information gathered from the rest of the nerves and transmitting instructions to the body. Messages to and from the CNS are carried by the nerves of the nervous system.
