The Uterus Duplex Bicollis, Vagina Simplex of Female Chinchillas.

The available literature describing the morphology of the female chinchilla's uterine cervix varies and includes phrases such as 'the cervical canal,' 'a single cervix,' and 'the cervix;' alternatively, some publications describe 2 cervices. In this report, we provide an anatomically correct and definitive description of the uterine cervical morphology of the laboratory chinchilla. We further propose revised, anatomically precise nomenclature to characterize the female chinchilla reproductive tract as a whole.
