Uterine structure Uterine form:

The uterus of an adult without birth is slightly flat, inverted pear-shaped, about 7-9 cm long and about 2-3 cm thick. Divided into the bottom, body and neck three parts. The bottom of the uterus is the bulge above the level of the fallopian tube uterus; the lower end is narrow and cylindrical in shape as the cervix, which is about 2.5-3 cm long in adults and is the site of tumors; The cervix is divided into two parts, the vaginal portion of the cervix protruding into the vagina and the upper part of the cervix and vagina above the vagina. The upper end of the cervix and the uterine body are relatively narrow and are called uterine gorge, which is about 1 cm long. During pregnancy, the uterine gorge gradually expands to form the lower uterine segment; at the end of pregnancy, it can be extended to 7-11 cm, and the gorge wall gradually becomes thin. Obstetrics often perform cesarean section here to avoid entering the peritoneal cavity and reduce infection Opportunity.

The uterine cavity is divided into two parts: the upper part is inside the uterus, called the uterine cavity; the lower part is inside the cervix, called the cervical canal. The uterine cavity is an inverted flat triangle, with the fallopian tubes at the upper ends and the cervical cervix extending downward. The cervical canal is fusiform, and the lower mouth is connected to the vagina, which is called the uterine mouth. The parturient uterine mouth is mostly round; the parturient uterine mouth is transversely fissured, and the front and rear edges are called the front and rear lips, respectively. The rear lip is longer and the position is higher. When an adult is not pregnant, the distance from the uterine mouth to the uterine floor is about 6-7 cm, the uterine cavity is about 4 cm long, and the widest point is about 2.5-3.5 cm.

The structure of the uterine wall:

The uterine wall is divided into three layers, the outer layer is the serosa and the visceral layer of the peritoneum; the middle layer is a thick muscular layer composed of smooth muscles; the inner layer is the mucosa, the endometrium, which proliferates and falls off with the menstrual cycle. Cyclical changes.

The location of the uterus structure uterus:

The uterus is located in the center of the small pelvis, between the bladder and the rectum; the lower segment connects the vagina, and there are fallopian tubes and ovaries on both sides. At the end of pregnancy, the uterine floor is below the level of the pelvic entrance, facing upwards; the lower end of the cervix is slightly above the level of the sciatic spine. When standing upright, the uterus is shaped above the bladder. When the bladder is empty, the uterus of the adult is slightly forward leaned forward, that is, the entire uterus leans forward, and an obtuse angle is formed between the long axis of the uterus and the long axis of the vagina, which is slightly larger than 90 degrees. Forward flexion refers to the fact that the uterine body and the cervix are not in a straight line, and an obtuse angle that opens forward is about 170 degrees. The uterus has greater mobility, and the fullness of the bladder and rectum can affect the position of the uterus.

Uterine fixation device

The uterus maintains its normal position mainly by the support of ligaments, pelvic ridges, and urogenital ridges, and the pulling of surrounding connective tissue. If these fixation devices are weak or damaged, it can cause abnormal uterine position and cause different degrees of uterine prolapse. The uterine mouth is lower than the level of the ischial spine. In severe cases, the cervix can prolapse from the vagina.
