Nasal Cavity Olfactory Region Histology

Olfactory epithelium cells

1. Olfactory cells
2. Sustentacular cells - located mainly in the superficial cell layer of the epithelium (difficult to distinguish from olfactory cells).
3. Basal cells - identified by their location in the epithelium.

Epithelium

• Cilia are not visible
• goblet cells are absent from the olfactory epithelium.

Lamina Propria

• olfactory axon bundles (lightly stained, rounded areas) connected to olfactory cells.
• Bowman's glands - (small mucous glands, olfactory glands) function to moisturise the epithelium.
