Abstract

Are there several types of respiratory epithelium in the upper part of the respiratory tract or only one? This question was suggested by the finding of areas in the anterior portion of the nose, which exhibited little if any ciliary activity.1 These areas were invariably found where the impact on the epithelium of the inspired air was greatest. The preturbinal region, the anterior ends of the middle and inferior turbinates, the anterior portion of the septum, the anterior aspect of spurs and polypi and the tops of ridges on the septum were found to be thus inactive. If the cartilaginous septum was deviated, the inactive spots and spots exhibiting ciliary activity were found distributed on the two sides according to the exposure to inspired air. The exposed spots were inactive and the protected areas active. If a ridge or fold in the cartilaginous septum extended far enough
