Análise macroscópica e microscópica da glândula prepucial do Quati

Abstract

The purpose of this research is to describe the nasua nasua foreskin gland. Eight coatis from the CECRIMPAS Scientific Creatory (UNIFEOB) were used, the preputial glands were analyzed, dissected and described macro and microscopically, in order to establish their morphofunctional classification and thus be able to compare them with those of other species already described in the literature. Glandular tissue samples were collected, stained (hematoxylin and eosin, Toluidine blue, and picrosirius) and analyzed using light microscopy. All results were compiled and photo-documented. In the mentioned species, this gland has as its main function the territorial demarcation. In other animals such as primates, deer and rodents these demarcating glands are located in different anatomical regions, such as between the eyes, in the metatarsal, perianal and sternal. In our result of biometric measurements, we obtained an average of 3.8 ± 1.41 cm in width, 3.15 ± 0.93 cm in height and 10.26 ± 1.89 cm in circumference, and histologically classified as the tubuloalveolar type, with holocrine secretion.
