The vascular propria submucosa had mucous glands, which were positive to periodic acdic shieff and Alcian blue stains. The olfactory region was lined with thick pseudostratified columnar epithelium devoid of goblet cells and contained, the propria submucosa serous simple acinus Alcian positive glands (Bowman's glands) and numerous nerve bundles.
