Goblet cells respiratory system
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 basement membrane and are, therefore, a single layer of cells, their nuclei are not aligned in the same plane. Hence, it appears as though several layers of cells are present and the epithelium is called pseu… WebCellular and molecular mechanisms of goblet cell metaplasia in the respiratory airways The mucociliary system, consisting of mucus-secreting goblet cells and ciliated cells, …
