WebBipolar neurons are usually oval in shape and contain two processes, a dendrite that receives signals usually from the periphery and an axon that propagates the signal to the central nervous system. Bipolar neurons are found in sensory organs, such as the retina, olfactory epithelium, and the auditory system. • Humans have between 10 and 20 million olfactory receptor neurons (ORNs). In vertebrates, ORNs are bipolar neurons with dendrites facing the external surface of the cribriform plate with axons that pass through the cribriform foramina with terminal end at olfactory bulbs. The ORNs are located in … See more An olfactory receptor neuron (ORN), also called an olfactory sensory neuron (OSN), is a sensory neuron within the olfactory system.
