The uterus can be divided anatomically into four regions: the fundus – the uppermost rounded portion of the uterus above the openings of the fallopian tubes, [4] the body, the cervix, and the cervical canal. The cervix protrudes into the vagina. The uterus is held in position within the pelvis by ligaments, which are part of the endopelvic ...
The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
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. The uterine ...
Known as uterus didelphys, this is “part of a spectrum of disorders that are referred to as Müllerian abnormalities,” says Erin Higgins, an ob-gyn doctor at the Cleveland Clinic, which has a ...
Around 2–3 centimetres (0.8–1.2 in) in length, [3] it is the lower narrower part of the uterus continuous above with the broader upper part—or body—of the uterus. [4] The lower end of the cervix bulges through the anterior wall of the vagina, and is referred to as the vaginal portion of cervix (or ectocervix) while the rest of the ...
The part of the decidua that interacts with the trophoblast is the decidua basalis (also called decidua placentalis), while the decidua capsularis grows over the embryo on the luminal side, enclosing it into the endometrium.
Müllerian duct, the upper part of which remains as the hydatid of Morgagni; the lower part, represented by a dotted line descending to the prostatic utricle, constitutes the occasionally existing cornu and tube of the uterus masculinus: ot. The genital ridge from which either the ovary or testis is formed. o. The left ovary: t.
The lower portion of the oviduct, or uterus, has a thicker layer of smooth muscle and contains the glands that secrete the egg shell. In marsupials and placental mammals, the uterus becomes lined by an endometrium, [1] and is more developed than in egg-laying amniotes. In many placental mammals, the uteri of each side become partially or wholly ...
