In bilaterally symmetrical organism, it is arranged in a network of tree-like structures connected to a central body. The main functions of the nervous system are to regulate and control body functions, and to receive sensory input, process this information, and generate behavior [CUMBO]. MIAA:0000026 A regulatory system of the body that consists of neurons and neuroglial cells. The nervous system is divided into two parts, the central nervous system (CNS) and the peripheral nervous system (PNS).
