histological study of human respiratory nasal mucosa: observations on glands

Mucosa of nasal septum, inferior turbinate and inferior meatus from eighteen autopsy cases of both sexes was studied. Observations showed that stroma was rich in connective tissue, blood vessels and glands. Collagen fibers were more than elastic fibers. Blood vessels were mostly subepithelial, and periglandular. Glands were of mixed type. The difference between serous and mucous cells of the septal, meatal and conchal regions of the same side was statistically significantant [p < 0.05]. In septal and inferior meatal region, the ratio of serious and mucous cells was approximately 2:1. In inferior conchal region their ratio was approximately 3:1
