Final answer:
A neuron that is not bipolar or unipolar is typically a multipolar neuron with one axon and multiple dendrites, found within the CNS.
Step-by-step explanation:
Any neuron that is not a bipolar or unipolar neuron is usually a multipolar neuron whose axon does not leave the central nervous system (CNS) in which it resides. Multipolar neurons are characterized by having one axon and two or more dendrites. Unlike unipolar neurons, which are not commonly found in vertebrates but in insects, and bipolar neurons, such as retinal cells, multipolar neurons include most of the neurons within the CNS. An example of a multipolar neuron is a Purkinje cell in the cerebellum, which is distinguished by many branching dendrites and a singular axon.
