Question to women and gynecologists
- That's curiosity ... See him ... You can reach out, but not at all.
- If you insert a finger into the vagina, you can reach only the cervix. And then with difficulty. . And the uterus, in my opinion, is small, looks like a fist ..
- Look here. link is blocked by the decision of the project administration
- The uterus is a smooth-muscular hollow organ located in the pelvic area. In shape, the uterus resembles a pear and is mainly intended for bearing a fertilized egg during pregnancy. The weight of the uterus of the nulliparous woman is about 50 (for the nulliparous from 30 to 50, for those giving birth from 80 to 100), the length is 7 8 cm, and the largest width is about 5 cm. However, during pregnancy, due to the elastic walls , the uterus can grow to 32 cm in height and 20 cm in width, sustaining a fruit weighing up to 5 kg. In the climacteric period, the size of the uterus decreases, atrophy of its epithelium occurs, sclerotic changes in blood vessels.
The uterus is located in the cavity of the small pelvis between the bladder and rectum. Normally it is tilted anteriorly, on both sides it is supported by special ligaments that do not allow it to descend and, at the same time, provide the necessary minimum of movement. Due to these ligaments, the uterus is able to react to changes in neighboring organs (for example, bladder overflow) and to adopt an optimal position for itself: the uterus can move back when the bladder is filled, forward with a rectum overflow, rise up during pregnancy.
The attachment of the ligaments is very complicated, and it is his nature that is the reason why it is not recommended for a pregnant woman to raise her hands high: this position of the hands leads to a strain of the ligament of the uterus, to the tension of the uterus itself and its displacement. This, in turn, can cause unnecessary displacement of the fetus during late pregnancy.
Among the disorders of the development of the uterus, congenital defects such as complete absence of the uterus, agenesis, aplasia, doubling, bicornic uterus, unicorn uterus, as well as hypoplasia, abnormalities of the position of the prolapse of the uterus, displacement, descent.
Diseases associated with the uterus are most often manifested in various disorders of the menstrual cycle. With problems of the uterus are associated with such problems of women as infertility, miscarriage, as well as inflammatory diseases of the genital organs, tumors.
In the structure of the uterus, the following departments are distinguished:
Cervix of the uterus
Isthmus of the uterus
Body of the uterus
The bottom of the uterus is its upper part
The cervix is a peculiar muscular ring, with which the uterus ends and which is connected to the vagina. The cervix is about a third of its entire length and has a special small hole in the cervical canal of the cervix, the uterine cavity through which it enters the vagina, and then outwards the menstrual blood. Through the same hole in the uterus penetrate the spermatozoa for the purpose of subsequent fertilization in the fallopian tubes of the egg. The cervical canal is closed by a mucous plug, which is ejected during orgasm. Spermatozoa penetrate precisely through this plug, and the alkaline environment of the cervix contributes to their stamina and mobility.
The shape of the neck differs in women giving birth and nulliparous. In the first case, it is round or in the form of a truncated cone, in the second it is wider, flat, cylindrical. Changing the shape of the cervix and after abortion, and to deceive the gynecologist after the examination is no longer possible.
The isthmus of the uterus is the area of transition between the cervix and its body about 1 in width. Its main function is manifested during childbirth, it helps to widen the hole and exit the fetus. In this area, uterine ruptures can also occur, since this is the thinnest part of it.
The body of the uterus is actually its main part. Like the vagina, the body of the uterus consists of three layers (shells).
- Firstly, it's the mucous membrane (endometrium). Another layer is called mucous. This layer lays the cavity of the uterus and is abundantly supplied with blood vessels. The endometrium is covered with a single-layer prismatic ciliated epithelium
The endometrium is subject to changes in the hormonal background of the woman: during the menstrual cycle, there are processes that prepare for pregnancy. However, if fertilization does not occur, the surface layer
