The nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The central nervous system this page outlines the basic physiology of the central nervous system including the brain and spinal cord.

The nervous system not only carries information about changes in your surroundings it also helps to coordinate all the different systems in your body. Effectors include cilia slender hairlike projections from the cell surface flagella elongated. Separate pages describe the nervous system in general sensation control of skeletal muscle and control of internal organs.

All of these cells need to work as a coordinated whole so that you can move around eat reproduce and carry out all the other characteristics of living organisms.
