The uterus (from Latin uterus, pl.: uteri or uteruses) or womb (/ w uː m /) is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more fertilized eggs until birth. [1]
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 ...
The cervical canal connects the interior of the vagina and the cavity of the body of uterus. The cervix is part of the female reproductive system. 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]
A retroverted uterus (tilted uterus, tipped uterus) is a uterus that is oriented posteriorly, towards the rectum in the back of the body. This is in contrast to the typical uterus, which is oriented forward (slightly " anteverted ") toward the bladder , with the anterior part slightly concave.
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 ...
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.
Uterine prolapse is a form of pelvic organ prolapse in which the uterus and a portion of the upper vagina protrude into the vaginal canal and, in severe cases, through the opening of the vagina. [4] It is most often caused by injury or damage to structures that hold the uterus in place within the pelvic cavity. [2]
