According to National Geographic, more than 60 opossum species inhabit the United States, Mexico and Canada. Although 'possums appear to be large rodents, they are actually marsupials. Opossums are omnivores that live in habitats such as woodlands, farmlands and even residential areas. Differences between male and female opossums abound.

The present study aimed at examining the gross and morphometry of the reproductive tract of the male bats (Eidolon helvum).Thirty male bats (adults and juveniles) were captured using net, weighed, aged using relative ossification of the wing bone, and dissected for gross logically, the mean body weight and forearm length in both adults and juveniles were g, cm and Cited by: 1.

    A. Female genital mutilation (2) Female genital mutilation (FGM), or female circumcision as it is sometimes erroneously referred to, involves surgical removal of parts or all of the most sensitive female genital organs. It is an age-old practice which is perpetuated in many communities around the world simply because it is customary. On the other hand, treating female young with male hormone tended to inhibit development of the vaginal segment of the female reproductive tract and to cause the genital tubercle to develop into a penis (,1,3; ).

Get this from a library. Development of the female genital tract in the American opossum. [James S Baxter]. The development of the female reproductive system requires an elaborate process. In females, reproductive organs divide into three main groups: gonads, reproductive ducts, and external genitalia.

The female reproductive system derives from four origins: mesoderm, primordial germ cells, coelomic epithelium, and mesenchyme. Since the publication of the 1/e inBlaustein's Pathology of the Female Genital Tract has consolidated its position as the leading textbook of gynecological pathology.

An essential reference for all pathologists and residents, this thoroughly updated Seventh Edition includes more than illustrations in color, informative tables and 22 revised chapters written by internationally recognized /5(8).

The female genital tract is formed by a complex series of events beginning in the fourth week of development. This process involves the formation of the gonads following germ cell migration from the yolk sac to the dorsal mesentery, formation and fusion of the müllerian ducts to create the uterine corpus and tubes, induction of squamous mucosa in the vagina and cervix, and a series of.

The main application of cytology to the female genital tract is in the early diagnosis of precancerous and cancerous lesions. Patients who have been treated for cervical cancer can be followed cytologically for response to radiation and recurrence of the by: 8.

This clear organization is applied throughout the book and allows the reader to quickly access key information in every chapter. Blaustein's Pathology of the Female Genital Tract remains the gold-standard reference for practicing pathologists and trainees, as well as for obstetric/gynecology practitioners and residents.

On the prenatal initiation of T cell development in the opossum Monodelphis domestica "Thymus-dependent lymphocytes (T cells) are a critical cell lineage in the adaptive immune system of all jawed vertebrates. In eutherian mammals the initiation of T cell development takes place prenatally and the offspring of many species are born relatively immuno-competent.

Possums (), by Carl G. Hartman. Possums is a page book consisting of a series of essays written about the Virginia opossum (Didelphis virginiana), the only living marsupial in the essays were written by Carl Gottfried Hartman, an embryologist at the Carnegie Institute of Washington (CIW), in Baltimore, Maryland, who also worked with another mammal, the rhesus monkey.

Female opossum with young in pouch With out a long-lasting and functional placenta, the young must be born early in their development after a short gestation period.

Marsupial young are basically embryos at birth. Once born, the young must climb with a swimming motion up the fur on the female’s adbomen and latch onto a teat. The anatomical aspects and biometry of the male genital system during the annual reproductive cycle were studied in fifty-one adult white-belly opossums (Didelphis albiventris Lund, ).Author: Elizabeth Brown Chase.

During the indifferent stage of sexual development, the urogenital tract of the embyro consists of two components: (1) two duct systems (wolffian and müllerian), derived from the mesonephros, and (2) the urogenital sinus and genital tubercle.

Ambiguous genitalia constitute a rare phenotypic presentation of the urogenital system that can signal an underlying life threatening disorder. Thus, it is imperative to determine the etiology as quickly as possible when ambiguity is noted.

The formation of typical male or female external genitalia results from a number of genetic and physiological events starting with sex determination and Cited by: 4.

Some people need to learn this in more depth than others, but we are fascinating individuals. Although they look like a big rat, the opossum is North America’s only marsupial and is related to the Kangaroo and Koala.
