Four Neuron Types

The idea
Neurons divide structurally into unipolar, bipolar, multipolar, and pseudounipolar types, distinguished by how many processes extend from the soma and how they branch.
In practice
Most sensory neurons are pseudounipolar, with a single process that later splits into two branches.
Where people slip
Pseudounipolar is not the same as unipolar — a pseudounipolar neuron's single process still splits into two functional branches.
