Pseudostratified Columnar Epithelium
Nasal Cavity Respiratory Mucosa 400X
Pseudostratified ciliated columnar cells with scattered goblet cells (Gc) line the respiratory mucosa of the nasal cavity of a rat. Only the tallest pseudostratified cells reach the free surface of the epithelium. Their nuclei are located at different levels above the basement membrane. The underlying connective tissue of the lamina propria is present at the bottom of the micrograph. A mucous layer produced by the goblet cells can be seen covering the cilia.
Trachea Respiratory Mucosa 400X
The respiratory mucosal lining of the trachea is composed of pseudostratified ciliated columnar epithelium mixed with mucous-secreting goblet cells. The basement membrane (Bm) or lamina, and the lamina propria (Lp) composed of loose connective tissue with darkly stained fibroblasts, can be identified in the image.
