A bipolar neuron has two main processes extending from its soma, conventionally an axon and a dendrite. Retinal bipolar cells provide a sensory example connecting photoreceptors to downstream retinal circuitry. The anatomical label does not mean that the biological cell has two axons, and it does not imply that every signal must be an action potential.[ref]
