A neuron only has 1 axon.

• A. True
• B. False
• C. Typically two
• D. It depends on neuron type

Answer: (A)

Neurons are typically organized with a single output path, the axon, that carries signals away from the cell body. The axon originates at the axon hillock and can branch along its length, but there is usually just one axon per neuron. Dendrites, by contrast, are the multiple input branches that receive signals.

That single-axon pattern is what you most often learn in histology, so the statement is true for the vast majority of neurons. There are exceptions in biology—some neurons may lack a distinct axon (anaxonic) or have processes that resemble both dendritic and axonal roles—but these are special cases and not the norm. Thus, describing a neuron as having only one axon is the best general answer.
