WebMorphology of Olfactory Mucosa and Cell Types. The olfactory mucosa consists of a layer of columnar epithelium, surrounding millions of olfactory neurons, which are the only neurons to communicate with the external environment and undergo constant replacement. Basal cells near the lamina propria undergo differentiation and develop into these ... WebOlfactory hairs that bind with odorants cover the dendrites. When an odorant stimulates a receptor cell, the cell sends an electrical impulse to the olfactory bulb through the axon at its base. Supporting cells provide structure to the olfactory epithelium and help insulate receptor cells. They also nourish the receptors and detoxify chemicals ...
