Bone tissue has different models of vascularization, cellular distribution, mineralization and remodeling among mammals species. A variety of dietary habits associated with the mode of locomotion and habitat required from bats the establishment of different flying styles and some skeletal adaptations. This study aimed at examining the microscopic characteristics of mature bone tissue of Glossophaga soricina (Phyllostomidae, Chiroptera). Twelve animals of both genders were used, in which the right humerus were dissected, weighed, decalcified and submitted to routine histological processing. Semi-serial cuts of 5 micrometers were stained with hematoxylin and eosin (H.E.), picrosirius red and silver nitrate 50%. The histological preparations were subjected to histological and histomorphometric analysis. Lacunae density was significantly higher in humerus of females when compared to males (33.96 x 27.80, p = 0.02). Microscopic analysis indicated the presence of parallel collagen fibers distributed in the bone matrix. Lacunes presented various shapes and canaliculi are well distributed and individualized. Few Havers systems and canals were observed. The mature bone tissue of the humerus Glossophaga soricina share microscopic features with other mammals, however, differences in the structural organization are peculiar to this species.
