Block1/Fig 4. The microscopic structure of trachea.

block1_14.jpg - Fig 4. The microscopic structure of trachea.The lining of the trachea consists of pseudostratified ciliatedcolumnar epithelium. Although the epithelium appears to formthe stratified, but all the cells rest on the basement membrane.The wall of the trachea contains the C-shaped tracheal cartilage.Besides, the tracheal cartilage is surrounded by the regulardense regular connective tissue (DCT). The collagen fibers arearranged in a regular manner and the fibroblast nuclei areelongated in the direction of the collagen fibers. By the way,adipose tissue (Ad) and nerve fiber bundles (NB) could be seenin this micrograph. Pseudostratified ciliated columnarepithelium appears at higher magnification in Fig 6b, and thecilia (C) is well demonstrated in this figure.
