What Is the Function of the Olfactory Epithelium?

The nasal mucosa is divided into two parts, the olfactory area and the respiratory area, according to its histological structure and physiological function.

Olfactory mucosa

Olfactory mucosa
The olfactory layer of the olfactory region contains the olfactory glands that secrete serous fluid to dissolve the particles of odorous substances and produce an olfactory sense. Olfactory cells are bipolar nerve cells. The central axon collects the olfactory filaments of most olfactory cells and passes through the sieve plate to the olfactory bulb. The surrounding axons protrude from the epithelial surface and become slender olfactory hairs.
