What is the posterior wall of the uterus?

The uterus is the most important internal organ of women. At the same time, the uterus of women also has the function of nurturing life. The posterior wall of the uterus is where the fetus grows. The uterus is divided into the anterior wall, the uterine cavity, the cervix, and the posterior wall. The posterior wall of the uterus is the position behind the uterus. It is where women have menstruation and the fetus grows. It is very important to the body.

To put it simply, the uterus is like a round house, and the wall at the back is the back wall. Is the placenta on the back wall? It is normal for the fetus's placenta to grow on the back wall of the uterus. If you have had a cesarean section before, you can rest assured that scar pregnancy, dangerous placenta previa, etc. will not occur.

In ultrasound description, the uterus is divided into the anterior wall, posterior wall, cervix, fundus, and uterine cavity. The posterior wall of the uterus is the back wall of the uterus.

The uterus is the organ that produces menstruation and nurtures the fetus. It is located in the center of the pelvic cavity, between the bladder and the rectum. The size of the uterus is related to age and fertility. For nulliparous women, it is approximately 7.5 cm long, 5 cm wide, and 3 cm thick. The uterus can be divided into three parts: the fundus, the body, and the neck. The uterine cavity is an inverted triangle, about 6 cm deep, with the two upper corners being the "uterine horns" that lead to the fallopian tubes. The narrow lower end is called the "isthmus", which is about 1 cm long. The isthmus gradually expands during pregnancy and forms the lower uterine segment at the time of delivery.

The ratio of the uterine body to the cervix varies with age, being 1:2 in infancy, 1:1 in adolescence, and 2:1 during the reproductive period. The uterus is normally slightly curved forward, with the anterior wall lying prone on the bladder and almost at right angles to the vagina. Its position may change with the degree of fullness of the bladder and rectum. The uterine wall is composed of three layers from outside to inside: serosa, muscle layer and mucosa (i.e. endometrium).

The endometrium is the mucosa, which is composed of epithelium (single-layer columnar epithelium, which has two types: secretory cells and ciliated cells) and lamina propria (composed of connective tissue, which contains a large number of astrocytes, called stromal cells). The endometrium can be divided into the superficial functional membrane and the deep basal layer. The functional layer is thicker, accounting for about 4/5 of the thickness of the endometrium, and the basal layer is thinner and denser, accounting for about 1/5. During the menstrual cycle, the functional layer can be peeled off, while the basal layer cannot.

The uterus, also known as the uterus and the female womb, is a name inherent in traditional Chinese medicine and belongs to the extraordinary palace. The name of uterus was first seen in the entry for purple quartz in Shennong's Herbal Classic, which states that it is used to treat "wind-cold in the uterus of women, who have been infertile for ten years."
