Trachea. Illustrated is the mucosal lining of the trachea. It consists of respiratory epithelium (pseudostratified ciliated columnar epithelium with goblet cells) and a lamina propria. The yellow line shows the separation between the two. The epithelial nuclei closest to the lumenal surface are those of the ciliated and brush cells while those closest to the basal lamina belong to the basal and the small granual cells.
