ABSTRACT
Morphology of the uterus and mammary glands were studied in sexually matured female African giant rat. The uterus was identified as being duplex, having two separate uterine horns and two cervices. The two cervices were partially fused and separated by a mid-saggital septum. Their thick musculatures projected caudally into the vagina as the portio vaginalis uteri. The results also showed that eight mammary glands, distributed along the lateral aspects of thoracic and inguinal regions, were present. The thoracic and the inguinal regions had four mammary glands each and were arranged in two pairs of cranial and caudal rows. These findings fill some gaps created by the dearth of information on the reproductive biology of the female African giant rat.
RESUMEN
La morfología del útero y las glándulas mamarias fueron estudiadas en ratas Africanas gigantes sexualmente maduras. El útero fue identificado como doble, teniendo dos cuernos uterinos separados y dos cervix. Los dos cervix estaban parcialmente fusionados y separados por un tabique mediano sagital. Su grosor muscular se proyecta caudalmente en la vagina como la porción vaginal del cuello uterino. Los resultados también mostraron que ocho glándulas mamarias, distribuidas a lo largo de las zonas laterales de tórax y la región inguinal estaban presentes. La región torácica e inguinal tenía cuatro glándulas mamarias en cada lado y se organizaron en dos pares de filas craneales y caudales. Estos hallazgos completan algunas lagunas creadas por la escasez de información sobre la biología reproductiva de la rata gigante Africana hembra.
