Scanning Electron Microscopy Of The Nasal Mucous Membrane

Abstract

The structures of components of the nasal mucous membrane have been studied by means of the scanning electron microscope. The mucous covering the lining epithelial cell as well as intercellular ground substance in the subepithelial layer has been clearly visualized. The following patterns of the structures have been characterized in this study: Noodlelike shape of cilia of the ciliated cell; club-like process of microvilli of the goblet cells; polygonal shape with numerous microvilli of the basal cells; bundles and meshworks of the connective tissue fibers; numerous pores on the inner wall of the venules; microvilli and secretory granules of the inner surface of the terminal portion of the secretory glands, and spiral pattern of the inner wall of the secretory ducts.
