Histology - Pseudostratified columnar epithelium


This section of pseudostratified columnar epithelium is from the mucosal lining of the trachea has a ciliated surface. Notice the classic layering of the nuclei within the epithelium that give it the stratified appearance. What appears stratified is, however, a single layer. The nuclei nearer the surface belong to the taller ciliated cells of the epithelium, while the deeper situated nuclei belong to the wedge-shaped basal cells that do not reach the surface, but instead are wedged between the taller cells. Notice the mucous secreting goblet cells present in the tissue.
