The study aimed to describe the lung lobation of the brown brocket deer, Mazama gouazoubira. Two animal of the species, obtained postmortem by trampling on the highway, were used for the study, according to criteria of the Governing Law (1.153/95). The skin was completely removed and the animals were fixed in 10% formaldehyde. The viscera were removed and the lungs were dissected by a section of the block in the thoracic trachea and other structures of the pulmonary hilum. The lungs and bronchial tree were dissected, photographed and the images were recorded with a digital camera (Sony a200 Camera, 10.2mpx). The lungs showed themselves united by structures that penetrate the region of the pulmonary hilum, the right lung was found to be composed of the cranial lobes (segment cranial and caudal segment), middle, caudal and accessory. The left lung showed only cranial lobe (segmented into the cranial and caudal part) and caudal lobe. The bronchial tree begins emerges to the right lung one tracheal bronchus above the bifurcation of the trachea that are sequentially named right and left main bronchi, which at the level of the pulmonary hilum penetrate the left and right lungs respectively. The lungs and bronchial tree of M. gouazoubira showed the same anatomical description of other ruminants, like buffaloes, sheep and cattle. |
