If you think of a person as a city, the nervous system of the human body is comparable to the main computer control system that controls the main functions of the city.

Whether it is the human body or the city, it is the dominant system in the body.

After receiving various information from the internal and external environment by the receptors, it is transmitted to the centers at all levels of the brain and spinal cord through the peripheral nerves for integration, and then the peripheral nerves control and regulate the activities of various systems and organs of the body, so as to maintain the relative balance between the body and the internal and external environment.

The composition of the human nervous system is also strikingly similar to the structure of a computer system.
