Picture of the position of the cervix and uterus

The Creator created "women" and gave them uteruses so that they could create the birth of new life. The uterus is a very important organ for women. It shoulders a very important responsibility, making girls women and women mothers. As women, it is an indispensable organ in our bodies. Not only women need to thank it, but men also need to thank it because it brings us the birth of new life. However, apart from gynecologists, how many people really understand the uterus? What does it look like?

Photos of the position of the cervix and uterus

The position of the external cervical opening in the vagina determines the type of uterine position. The normal position of the uterus in an adult woman is a slightly extended and flexed position. "Tilt" refers to the angle between the short axis of the uterine body and the short axis of the vagina; "flexion" refers to the angle between the short axis of the uterine body and the short axis of the cervix. Normal extension means that the uterus and the vagina form an angle of inclination that opens forward and is similar to an oblique angle; normal flexion means that the uterus and the cervix form a flexion angle of about 170° that opens forward. The external cervical opening and both lips touch the inner posterior wall of the vagina. Various physiological or pathological factors can cause changes in the angle of "tilt" and "flexion" of the uterus, resulting in different types of uterine displacement: anterior displacement (extension, flexion, extension-flexion), posterior displacement (retroverted tilt, retroflexion, retrotilt-retroflexion and horizontal position) and lateral displacement (lateral tilt, lateral flexion, lateral tilt and lateral flexion), etc.

The cervix is ​​one of the key organs in the female urinary system. From embryos and fetuses to old age, the cervix is ​​involved in disease prevention and health care issues such as gynecology, obstetrics, family planning, prenatal and postpartum care, and reproductive health throughout a woman's life. It involves women's own physical and mental health, family harmony, economic and social issues, and is also closely related to sex and reproduction. The cervix may have a variety of symptoms, including abnormalities in embryonic development, inflammation, neoplasia, benign tumors, malignant tumors, damage, cervical infertility, family planning policy, assisted reproductive technology, cervix and sex, cervical pregnancy, cervical dystocia and many other gynecological problems. The cervix is ​​an important defense to prevent pathogens from entering the internal reproductive organs, but it is also under the erosion of various pathogenic factors (childbirth, miscarriage, surgical damage to the cervix, etc.); and the cervical endometrium has many wrinkles and cracks, and it is difficult to eliminate the bacteria lurking here, which can easily cause cervical inflammation. This disease can be divided into acute and chronic types. The latter is often caused by the inability of the former to heal immediately. Chronic cervicitis is more common in clinical medicine. Its most obvious symptom is thick milky white mucus or purulent yellowish mucus leucorrhea. In addition, it may be accompanied by vulvar itching, lumbar pain, etc.

The uterus is located in the middle of the female pelvis, behind the bladder and in front of the duodenum. The normal uterus is an inverted flat pear-shaped organ, with flat internal oblique muscles and relatively prominent interosseous muscles, wide walls and small cavity, wide and acidic on the top, facing forward and upward; narrow and cylindrical on the bottom, inserted into the upper end of the vagina. The average length, width, and thickness of the uterus of an adult woman are 7×5×3 cm respectively, and the uterine volume is about 5 ml. Its location may vary depending on the level of bladder and duodenum filling or posture. When standing, the uterus is almost parallel to the horizontal plane, the fundus of the uterus lies on the upper and back side of the bladder, and the cervix is ​​maintained above the ischial spines.

A normal woman's uterus is in a slightly extended and flexed position. Protrusion refers to the angle of opening forward between the uterine axis and the vaginal axis, and flexion refers to the physiological curvature between the uterine body and the cervix. The normal position of the uterus is mainly maintained by structures such as the uterine tendons, pelvic diaphragm, urogenital diaphragm and perineum tendons. When these structures are damaged or relaxed, uterine prolapse may occur.
