In women of reproductive age, two layers of endometrium can be distinguished. These two layers occur only in the endometrium lining the cavity of the uterus, and not in the lining of the fallopian tubes where a potentially life-threatening ectopic pregnancy may occur nearby. [4] [5] The functional layer is adjacent to the
They may notice either a distinct "gush" or a steady flow of small amounts of watery fluid in the absence of steady uterine contractions. [8] Loss of fluid may be associated with the baby becoming easier to feel through the belly (due to the loss of the surrounding fluid), decreased uterine size, or meconium (fetal stool) seen in the fluid.

A hydrosalpinx is a condition that occurs when a fallopian tube is blocked and fills with serous or clear fluid near the ovary (distal to the uterus). The blocked tube may become substantially distended giving the tube a characteristic sausage-like or retort-like shape.
Uterine glands or endometrial glands are tubular glands, lined by a simple columnar epithelium, found in the functional layer of the endometrium that lines the uterus. Their appearance varies during the menstrual cycle. During the proliferative phase, uterine glands appear long due to estrogen secretion by the ovaries.
The fluid consists of cervical and endometrial mucus or in rare instances urine accumulated through a vesicovaginal fistula proximal to the obstruction. In some cases, it is associated with Bardet-Biedl Syndrome. [1] If it occurs in prepubertal girls, it may show up as abdominal swelling. It may be detected by using ultrasound.
The gestational sac is spherical in shape, and is usually located in the upper part (fundus) of the uterus.By approximately nine weeks of gestational age, due to folding of the trilaminar germ disc, the amniotic sac expands and occupy the majority of the volume of the gestational sac, eventually reducing the extraembryonic coelom (the gestational sac or the chorionic cavity) to a thin layer ...
Asherman's syndrome, also known as intrauterine adhesions, occurs when the basal layer of the endometrium is damaged by instrumentation (e.g., D&C) or infection (e.g., endometrial tuberculosis) resulting in endometrial scarring followed by adhesion formation that partially or completely obliterates the uterine cavity
The cervix consists of two parts; the upper part lies in the pelvic/abdominal cavity and the lower part is intravaginal. [1] Cervical effacement or cervical ripening refers to the thinning and shortening of the cervix. This process occurs during labor to prepare the cervix for dilation to allow the fetus to pass through the vagina. While this ...
