what is nervous system

Answer 1

The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. It is responsible for coordinating all of the body's activities, including movement, sensation, and thought processes. The nervous system can be divided into two main parts: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which includes all of the nerves that branch out from the CNS to the rest of the body.
