Bronchiole

This higher magnification images shows the components of the bronchiole wall. This larger bronchiole is lined by a pseudostratified columnar epithelium with cilia and goblet cells. Abundant, longitudinally arranged elastic fibers are located beneath the epithelium. The smooth muscle layer is composed of spiraling bands of muscle fibers. 600x
