The structure or shape of a neuron is determined by how many cytoplasmic processes extend from its cell body. Those that have one process are referred to as unipolar neurons (or pseudounipolar neurons). The cell body looks as if it sits to the side of the rest of the cell, and the cytoplasmic process is used to connect it with the cell's long axon. Bipolar neurons have two cytoplasmic processes attached to their cell body, one the axon and the other the dendrite. Both processes can have many smaller branches. Neurons that have three or more processes attached to their cell bodies are classified as multipolar neurons. One process is the axon and the remainder are dendritic processes. This is the most comon type of neuron.
