What is the name of the system that coordinates all of our activities?

The nervous system is responsible for coordinating and regulating all of the body's activities, including movement, sensation, thought, and behavior. It consists of the brain, spinal cord, and a network of nerves that extends throughout the body. The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS consists of all the nerves that extend from the CNS to the rest of the body.
