- Abstract
The black-tufted-ear-marmoset (Callithrix penicillata) as well as other representatives of the genus Callithrix, has a great importance in research, especially in biomedical studies. However there is still a lack in basic research, such as those covering aspects of their anatomy and physiology. Given the scarcity of information about the morphology of the respiratory system in Callithrix penicillata, this study aimed to describe the histological and ultrastructural aspects of the trachea, bronchus and lung of these animals through the use of scanning electron microscopy (SEM) and light microscopy. For the evaluation we used five adult specimens, three females and two males, which they had died of natural causes. SEM in the trachea and bronchi were observed a dense surface of capillaries protruding numerous pores of Kohn, the hyaline cartilage and smooth muscle bundle arranged in a spiral. Already with regard to the lungs was the observation of the same structures typical of a mammalian lung. In light microscopy both the trachea, bronchi and lungs were similar to the structures already described for other species of primates non-human. The data obtained in this study elucidate the histological and ultrastructural morphology of the trachea, bronchi and lungs of the black-tufted-ear-marmoset (Callithrix penicillata). Thus serving as a grant for studies of comparative anatomy as well as knowledge about the morphology of this kind of non-human primate.
