Aside from the types of neurons according to function mentioned, we have the types of neurons according to structure

The types of neuron according to structure are:

• Multipolar – these are neurons having one axon and many dendrites

• Unipolar or pseudo unipolar – these are neurons having an axon that bifurcates close to the cell body with the longer branch extending toward PNS and the other towards the CNS

• Bipolar – neurons with one dendrite and one axon

• Anaxonic – neurons with many dendrites but have no true axon. It does not produce action potentials but regulate electrical charges of adjacent neurons
