Ultraestructura de los acinos sudoríparos de las glándulas pelvianas de Chaetophractus villosus (Mammalia, Dasypodidae) Ultrastructure of sudoriparous acini of pelvian glands of Chaetophractus villosus (Mammalia, Dasypodidae)

Abstract

The acini of pelvian glands of Chaetophractus villosus (Desmarest, 1804) consisted of an inner layer of secretory cells and an outer layer of myoepithelial cells. Secretory cells have numerous secretory vacuoles. The secretion is released by exocytosis. Myoepithelial cells have numerous myofilaments that occupy much of the cytoplasm. There is a third cell type with an extremely electron-lucent cytoplasm.
