Naval Cavity Olfactory Region Histology

olfactory epithelium is formed by

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.

Note - Cilia are not visible and goblet cells are absent from the olfactory epithelium.

Lightly stained rounded areas in the lamina propria represent bundles of olfactory axons in the lamina propria. Small mucous glands, olfactory glands or Bowman's glands, in the lamina propria moisturise the epithelium.
