One way to classify neurons is by the number of extensions that extend from the neuron's cell body (soma). Bipolar neurons have two processes extending from the cell body (examples: retinal cells, olfactory epithelium cells).
The Olfactory Receptors. The olfactory mucosa contains the olfactory receptor neurons that are responsible for scent transduction. The transduction occurs in the olfactory receptors located on cilia at the ends of the olfactory receptor neurons.Odorant molecules can reach the olfactory receptors via a passive pathway or an assisted pathway.t is known that the olfactory receptors located in the same zone of the mucosa send their information to the same glomeruli. As well, the olfactory receptor neurons located in the same zone of the mucosa have similar properties that are not found in other zones.
