Morphology of the trachea and lung lobation of Leopardus pardalis (ocelot)

ABSTRACT:

The species Leopardus pardalis, popularly known as ocelot, is a medium sized cat with wide distribution in the national territory and is included in the list of species of Brazilian fauna threatened with extinction. This study aimed to characterize the macroscopic and microscopic aspects of the trachea and lung lobes in L. pardalis. Analyses were performed using five copies of ocelot, two males and three females, adults, three of these specimens died from being run over on highways nearby the municipality of Alta Floresta, and two donated after death by IBAMA to the Laboratory of Zoology and Animal Morphology. In the trachea specimens was a flexible tube formed by pairs of cartilaginous arches, with pseudo-stratified epithelium ciliated not in its inner lining, and other basic structures of this body. Lung proved as a body made up of lobes separated by cracks with a usual parenchyma to the other described mammals. With respect to the anatomic features of the trachea and lung were similar to other mammals, as in the microscopic aspects of the trachea showed certain peculiarities found differing from the other jobs. Regarding the appearance of the lung parenchyma histological characteristics did not differ with those described.
