| Description: | This is a pseudostratified ciliated columnar epithelium with goblet
cells. The tufts of cilia can be seen along with the apical dark line
representing the basal bodies of the cilia. The goblet cells resemble
classic wine glasses and the mucus stains grey-purple. You can see some
of the mucus being release at the apical portions of a few goblet
cells. Some of the small, round nuclei adjacent to the basal lamina
belong to the basal reserve cells. Notice the small blood vessels in
the lamina propria. The smooth muscle cells in the muscularis mucosae
are clearly demonstrated here. PK1578. S1. Original mag.100x. H&E.
