Typical bipolar neurons are rather rare in bodies of mammals, including humans. They are found in the retina, spiral ganglion #1, #2 and vestibular ganglion; the neurons consist of nerve cell bodies of a rounded or elliptical shape with a dendrite and axon that are branching off from the opposite poles.

Pseudounipolar neurons #1, #2 are typical of spinal ganglia:

• they are found at the periphery of ganglia underneath the connective tissue capsule;
• their cell bodies are rounded, they contain clear nuclei with well-marked nucleoli and are surrounded by flattened cells of oligodendroglia called satellite glial cells;
• when impregnated with silver salts, they show a single projection #1, #2. The projection arises from the cell body (“false solitude” effect), further branching in the shape of letter “T” into dendritic and axonal fibers.
