Morphology of the female reproductive tract of the brown howler monkey (Alouatta guariba clamitans)
Keywords:Primates, Reproductive organs, Morphology, Female
AbstractIt was studied the external morphology, topography and the measures of the reproductive tract (ovaries, uterus, vagina and uterine tube) in six howler monkey females (Alouatta guariba clamitans). The ovaries are large and ellipsoid, with a smooth or irregular surface. The uterine tubes are long and convoluted, with well-developed and abundant fimbrias. The uterus is simple and characterized by a long and well-developed cervix and a globular fundic portion. The vagina is a long chamber with thin walls covered with a folded mucosa. The urethra opens in a distinct bilobate papilla within the ventral vagina wall.
