Descrição anátomo-radiográfica do membro torácico da Preguiça-comum (Bradypus variegatus) e dos ossos longos do membro torácico do Tamanduá-mirim (Tamandua tetradactyla).

Abstract

Sloths and anteaters are xenartros mammals, which differ from other species, among other things, by the presence of sinsacro and xenartros processes. Due to their particularities, the objective was to describe the anatomical structure and accidents of the thoracic limbs of the common sloth, Bradypus variegatus, and the long bones of the anteater, Tamandua tetradactyla, by means of macroscopic and radiographic analyzes. The brown-throated sloth demonstrated a simpler bone structure, with few anatomical accidents, while lesser anteater presented some anatomical accidents similar to those described in other mammalian species, however, both also presented anatomical particularities, without previous description of them that were not previously described. The macroscopic and radiographic analysis revealed the same anatomical accidents, considering that the radiographic evaluations were performed in at least two orthogonal projections. Thus, from these results, the great anatomical variation of these species, in relation to other mammals, reveals that knowledge of their particularities is fundamental, especially in determining safer clinical and surgical procedures.
