The central nervous system contains the brain and spinal cord; the peripheralnervous system consists of nerves, motor neurons, the autonomic nervoussystem, and the enteric nervous system.The nervous system coordinates the voluntary and involuntary actions of thebody by transmitting signals from the brain to the other body parts.Nervous systems vary across different animals; some invertebrates lack a truenervous system or true brain, while other invertebrates have a brain and asystem of nerves.Unlike vertebrates, not all invertebrates have both a CNS and PNS; their nervecords are located ventrally rather than dorsally.The functions of the nervous system are performed by two types of cells:neurons, which transmit signals from one part of the body to another, and glia,which support the function of neurons.Neurons and Glial CellsFree to share, print, make copies and changes.

Dendrites are the tree-like structures in neurons that extend away from the cellbody to receive messages from other neurons at synapses; not all neurons havedendrites.Synapses enable the dendrites from a single neuron to interact and receivesignals from many other neurons.Axons are tube-like structures that send signals to other neurons, muscles, ororgans; not all neurons have axons.Neurons are divided into four major types: unipolar, bipolar, multipolar, andpseudounipolar.
