Does the nasopharynx have columnar epithelium?
The nasopharynx is also the only section of the pharynx to have pseudostratified columnar respiratory epithelium [6], the specialized epithelium (ciliated and containing goblet cells) for the respiratory tract [7]. These two epithelia have a sharp interphase between them, except for certain areas where an intermediate epithelium intervenes.
