Know Your Neurons: How to Classify Different Types of Neurons in
... Scientists have classified neurons into four main groups based on differences in shape. Multipolar neurons are the most common neuron in the vertebrate nervous system and their structure most closely matches that of the model neuron: a cell body from which emerges a single long axon as well as a cro ...
