Pseudostratified columnar epithelium
The lining epithelium of the trachea demonstrates a pseudostratified epithelium with cilia and gland cells (goblet cells). In a pseudostratified epithelium, all cells rest on the basement membrane, though not all reach the free surface. This variation in height, and thus position of the nuclei, give the impression of a stratified epithelium. 1000x
