The wall of the diaphragm will be affected by adjustments attributable to bodily trauma, permitting the passage of viscera between the belly cavity and thoracic cavity, thus lowering the area for pulmonary growth, resulting in the formation of hernia and attainable dying. Thus, we aimed to characterize, dimension and decide the topography of the diaphragmatic muscle within the Southern Tamandua, since medical and surgical actions in wild animals have change into a actuality increasingly more current in veterinary drugs. We used six grownup animals, x-rayed and dissected, adopted by assortment of fragments of muscular parts for histological evaluation. Initially we noticed that the animals offered 17 thoracic vertebrae, three lumbar vertebrae and 5 sacral vertebrae. The diaphragm was conformed by three segments: sternal, costal and proper and left diaphragm pillar, with presence of tendinous centre that housed the passage of the caudal vena cava, known as foramen of the caudal vena cava. Dorsally to the tendinous centre, already within the muscle portion, we situated the esophageal and aortic hiatus. These findings, in addition to the microscopic, had been equal to that discovered within the normal literature additionally, corroborating with descriptions already carried out in different mammals’ diaphragms.
