Olfactory epithelium main sensory cell
| Name: | Olfactory epithelium main sensory cell |
| Description: | This is the sensory neuron of the main olfactory epithelium in the nasal cavity that transduces odor molecules into receptor potentials, which give rise to the impulse trains that are sent further in the olfactory system.. It is a small bipolar cell in the pseudostratified olfactory epithelium, with cell body 8-15 um diameter giving rise to a single dendrite ending in a knob at the epithelial surface, from which arise several sensory cilia. A single unmyelinated axon descends through the basal lamina and turns to project to the glomeruli of the olfactory bulb. Shepherd, Chen & Greer.
