TITLE:

MORPHOLOGICAL CHARACTERIZATION OF OVARIES, UTERINE TUBES
AND UTERUS IN Pteronotus gymnonotus (CHIROPTERA: MORMOOPIDAE)

SUMMARY:

The present study aimed to characterize the ovarian, Fallopian tube and uterine
morphology of the insectivorous bat Pteronotus gymnonotus, in specimens collected
in the state of Rio Grande do Norte, Brazil. After euthanasia, such organs were
histologically processed for embedding in historesin for morphological and

morphometric analysis under light microscopy. The morphological characterization
of the ovaries was based on the development of the oocyte and follicle growth,
while the Fallopian tubes were characterized for of their anatomy and division into
infundibulum, ampulla and isthmus; as well for the height of the tubal epithelium
and thickness of the muscle layer. The analysis of the uterus was based on the
formation and thickness of its three layers: endometrium, myometrium and
perimetrium. Morphometric analyzes were performed by capturing images of the
histological slides at different magnifications. The variables were subjected to
descriptive statistical analysis, with data expressed as mean and standard deviation.
Analyzes are in progress. So far, it was possible to observe the follicular
quantification in the ovaries being represented by the percentage of the ovarian
components and the diameter of the follicles; the layers of the uterus and the
Fallopian tubes were observed and follow the same pattern as the other eutherian
mammals. This information is important to allow comparisons between species,
aiming at understanding the reproductive morphology in mammals, especially those
belonging to the order Chiroptera. Therefore, this research is essential to support
conservation measures that protect their natural populations, in an effort to maintain
the ecological balance.
