Uterus didelphys (from Ancient Greek di- 'two' and delphus 'womb'; sometimes also uterus didelphis) represents a uterine malformation where the uterus is present as a paired organ when the embryogenetic fusion of the Müllerian ducts fails to occur. As a result, there is a double uterus with two separate cervices, and possibly a double vagina ...
When the fetus has developed enough to survive outside the uterus, the cervix dilates, and contractions of the uterus propel it through the birth canal (the vagina), where it becomes a newborn. The breasts are not part of the reproductive system, but mammary glands were essential to nourishing infants until the modern advent of infant formula .
Colposcopy has historical roots in the 10th century when Abulcasis, a renowned Arabian physician, pioneered the use of reflected light to inspect internal organs, with the cervix being the first organ examined in this way. [2] [3] [4] The modern procedure was developed by the German physician Hans Hinselmann, with help from Eduard Wirths.
The cervix (pl.: cervices) or cervix uteri is a dynamic fibromuscular sexual organ of the female reproductive system that connects the vagina with the uterine cavity. [1] The human female cervix has been documented anatomically since at least the time of Hippocrates , over 2,000 years ago.
The uterine cavity is the inside of the uterus.It is triangular in shape, the base (broadest part) being formed by the internal surface of the body of the uterus between the openings of the fallopian tubes, the apex by the internal orifice of the uterus through which the cavity of the body communicates with the canal of the cervix.
f. Abdominal opening of the left uterine tube: g. Round ligament, corresponding to gubernaculum: g. Gubernaculum: h. Situation of the hymen: m, m. Right and left Müllerian ducts uniting together and running with the Wolffian ducts in gc, the genital cord: m.
The cervical canal is generally lined by "endocervical mucosa" which consists of a single layer of mucinous columnar epithelium. However, after menopause, the functional squamocolumnar junction moves into the cervical canal, and hence the distal part of the cervical canal may be lined by stratified squamous epithelium (conforming to a "type 3 transformation zone").
It has four described parts: the intramural part, isthmus, ampulla, and infundibulum with associated fimbriae. Each tube has two openings: a proximal opening nearest to the uterus, and a distal opening nearest to the ovary. The fallopian tubes are held in place by the mesosalpinx, a part of the broad ligament mesentery that wraps around the tubes.
