[Distribution and significance of nasal glands]

The distribution of nasal glands in the respiratory region of nasal cavities was studied. Four types of glands were found, namely: mucous, serous, seromucous and mucoserous glands, and were divided into high density, middle density and low density regions. High density regions of serous glands were mainly scattered in anterior part of the nasal septum, middle meatus, middle-posterior part of middle turbinate and nasal vault. Mucous, seromucous and mucoserous glands were well-distributed in the entire respiratory region with a low density. The distribution of nasal glands in the respiratory region is closely related to the physiologic functions of the nose and provides a pathological foundation for some diseases as well.
