| Description: | At this magnification, it is difficult to make out the cilia at the tip
of the ciliated cells in this respiratory epithelium. Goblet cells are
not obvious in this section. The smooth muscle cells of the muscularis
mucosae are very prominent as are the chrondrocytes of the hyaline
cartilage pieces. Notice that the serous glands are located external to
the muscularis mucosae, thus they are submucosal glands. There are two
arterioles in this sections. Are these 'functional' or 'nutritive'
blood vessels? PK1573. Original mag. 40x. H&E. Respiratory
