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.
A second study by the same group showed significant variations in size and shape between the vaginas of women of different ethnic groups. [4] Both studies showed a wide range of vaginal shapes, described by the researchers as "Parallel sided, conical, heart, [...] slug" [3] and "pumpkin seed" [4] shapes. Barnhart et al., however, were not able ...
However, landmark distances from the pubic symphysis are highly variable depending on body type. In clinical practice, recording the actual fundal height measurement from the palpable top of the uterus to the superior edge of the pubic symphysis is standard practice beginning around 20 weeks gestation.
The size of the uterus is assessed at the initial visit, and the growth of the uterus is assessed at subsequent visits. In the first trimester the uterine size can be assessed on bimanual examination. Subsequently, beyond the 12th week of gestation, the uterus can be felt above the pubic bone, and abdominal examinations assess growth. [24]
Each ovary is whitish in color and located alongside the lateral wall of the uterus in a region called the ovarian fossa. The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size. [3] [4]
The uterus, the muscular organ that holds the developing fetus, can expand up to 20 times its normal size during pregnancy. Head engagement, also called "lightening" or "dropping", occurs as the fetal head descends into a cephalic presentation.
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 ...
