Olfactory nerve cells in the nasal mucous membrane

The peripheral olfactory neuroepithelium of
the nasal mucous membrane consists of three
cell types: olfactory sensory neurons, whose
axons lead to the olfactory bulb, supporting
cells, and basal cells, which serve as stem cells
for the formation of olfactory neurons during
the individual’s entire lifespan. Each olfactory
neuron is bopolar, with olfactory cilia in the
lumen of the nasal mucous membrane and a
projection to the olfactory bulb, the first relay
station of the olfactory systemon theway to the
brain.
