The cells in the respiratory epithelium are of five main types: a) ciliated cells, b) goblet cells, c) brush cells, d) airway basal cells, and e) small granule cells (NDES) [6] Goblet cells become increasingly fewer further down the respiratory tree until they are absent in the terminal bronchioles; club cells take over their role to … Visa mer Respiratory epithelium, or airway epithelium, is a type of ciliated columnar epithelium found lining most of the respiratory tract as respiratory mucosa, where it serves to moisten and protect the airways. It is not … Visa mer The respiratory epithelium functions to moisten and protect the airways. It acts as a physical barrier to pathogens, as well as their removal in the mechanism of mucociliary clearance Visa mer • Cross-section of pseudostratified columnar epithelium • Second cross-section Visa mer The respiratory epithelium lining the upper respiratory airways is classified as ciliated pseudostratified columnar epithelium. This designation is due to the arrangement of the multiple cell types composing the respiratory epithelium. While all cells make contact with the Visa mer Long-term irritation of the epithelial cells can cause the overproduction of mucus, known as mucus hypersecretion. Mucus hypersecretion … Visa mer WebbMucous cells appear to play the dominant proliferative role and, resulting from a marked increase in their mitotic rate, pathological lesions are produced which include ‘goblet’ cell hyperplasia, stratification and noncornifying and …
WebbIn addition to the staple of basal cells, ciliated cells and goblet cells , the respiratory epithelium also contains brush cells, endocrine cells(or small granule cells, function not clear), surfactant-producing cells(or Clara cells), and serous cells.
