Microscopic Anatomy of the Lower Respiratory System of the African Giant Pouched Rat (Cricetomys gambianus, Waterhouse 1840)

A qualitative and quantitative study, by light microscopy, was undertaken on the lower respiratory system of the African Giant pouched rat. Specifically, the trachea, bronchi and lungs were stained with Haematoxylin and eosin, Alcian blue at a pH of 2.5 and Periodic Acid-Schiff stains. Three cell ty...

ISalami,S. ONzalak,J. O African Giant pouched rat Lower respiratory system Histology A qualitative and quantitative study, by light microscopy, was undertaken on the lower respiratory system of the African Giant pouched rat. Specifically, the trachea, bronchi and lungs were stained with Haematoxylin and eosin, Alcian blue at a pH of 2.5 and Periodic Acid-Schiff stains. Three cell types were identified in saggital sections of the trachea: the ciliated cells, basal cells and mucous cells. Fibers of the trachealis muscles in the laminar propria separated the underlying cartilages from the basal cells. Mucous cells were visible only in the membranous portion of the trachea and they were predominant in the rostral and caudal portion of the trachea. Lobar bronchi consisted of cuboidal epithelium and a layer of one or two smooth muscle cells and opened into segmental bronchi and respiratory bronchiole. Some tracheal cartilaginous rims stained blue with AB while most glandular cells stained red with PAS. The diameter of respiratory bronchiole, alveoli duct and alveoli were 24.93 µm (± 1.27), 21.14 µm (± 0.66) and 12.95 µm (± 0.21), respectively.
