Explanation:

The nervous system is a network that sends messages in both directions between the brain and different parts of the body. It does this through the spinal cord, which runs down the back from the brain. It contains nerves inside, some filaments that branch off to the other organs and parts of the body.

The nervous system is a complex set of cells in charge of directing, supervising and controlling all the functions and activities of the body's organs.

Much of living beings, as well as humans, have nervous systems. However, there are organisms that do not have it, such as protozoa and porifers.
