A neuron has a soma (cell body) from which processes emerge. The processes that receive information from synapses are called dendrites, while the process that carry the information from the soma is called the axon. Neurons have only one axon. The axon emerges from the axon hillock and is covered by glial cells, in this case an oligodendrocyte of the CNS, that form the myelin. If the neuron was in the PNS, its axon would be covered by other glial cells called Schwann cells. Gaps between the myelin are called nodes of Ranvier. The axon ends in branches at the axon terminal and the branches enlarge at their ends to form synaptic end bulbs.
