<P> A typical neuron consists of a cell body ( soma ) , dendrites , and an axon . The term neurite is used to describe either a dendrite or an axon , particularly in its undifferentiated stage . Dendrites are thin structures that arise from the cell body , often extending for hundreds of micrometers and branching multiple times , giving rise to a complex `` dendritic tree '' . An axon ( also called a nerve fiber ) is a special cellular extension ( process ) that arises from the cell body at a site called the axon hillock and travels for a distance , as far as 1 meter in humans or even more in other species . Most neurons receive signals via the dendrites and send out signals down the axon . Numerous axons are often bundled into fascicles that make up the nerves in the peripheral nervous system ( like strands of wire make up cables ) . Bundles of axons in the central nervous system are called tracts . The cell body of a neuron frequently gives rise to multiple dendrites , but never to more than one axon , although the axon may branch hundreds of times before it terminates . At the majority of synapses , signals are sent from the axon of one neuron to a dendrite of another . There are , however , many exceptions to these rules : for example , neurons can lack dendrites , or have no axon , and synapses can connect an axon to another axon or a dendrite to another dendrite . </P>
