S. Saari, A SEM STUDY OF THE MORPHOLOGY OF THE LOWER RESPIRATORY-TRACT SURFACE OF THE REINDEER (RANGIFER-TARANDUS-TARANDUS L), ANAT HISTOL, 24(3), 1995, pp. 165-169
The morphological features of the surface of the lower respiratory tra
ct (trachea, bronchus, bronchiolus, distal airways, and alveoli) from
10 reindeer (Rangifer tarandus tarandus L.), differing in age and sex,
were studied using scanning-electron microscopy. The respiratory surf
ace of the reindeer generally resembles that reported previously in si
milar studies for other mammalian species. Ciliated epithelial cells,
goblet cells, microvillous cells, Clara cells, alveolar epithelial cel
ls of type 1 and type 2, and alveolar macrophages could be distinguish
ed by their universally characteristic surface morphologies. The rarit
y of Kohn pores in the alveolar walls of reindeer was considered to be
the most striking difference in comparison to most other species.
