Final answer:
Neurons can be classified based on their structure, such as the number of processes attached to the cell body and their shape.
Step-by-step explanation:
Neurons can be classified based on their structure.
One way to classify neurons is by the number of processes attached to the cell body. If a neuron has only one process or fiber that divides into two branches, it is called a unipolar neuron. On the other hand, if a neuron has multiple processes, it is called a multipolar neuron.
Another way to classify neurons is by their shape. There is a wide variety of neuron shapes found in different parts of the nervous system. For example, a pyramidal cell has a cell body shaped like a pyramid, and a Purkinje cell in the cerebellum is named after the scientist who discovered it.
