Where is the uterus located?

It has to be admitted that the uterus does play a dominant role in the female reproductive system, especially when nurturing the next generation, the fetus mainly lives in the uterus. At the same time, uterine problems are also common, such as common uterine inflammation. Most uterine problems will cause symptoms of uterine pain, so female friends may wonder where the uterus is located in the body?

The uterus is located in the center of the pelvic cavity in the lower abdomen of the human body, between the bladder and rectum. It is composed of the uterine fundus, uterine body, uterine isthmus and cervix.

The cervix is ​​part of the uterus, which refers to the part below the isthmus of the uterus and the internal os of the cervix. It is cylindrical in shape, with the upper part connected to the isthmus of the uterus called the internal os of the cervix, and the lower end is the external os of the cervix. During a gynecological examination, what can be seen is the part of the cervix that extends into the vagina and the external os of the cervix. The shape of the external cervical opening varies from person to person. For women who have not given birth, the external os of the cervix is ​​a small and neat round or oval hole; for women who have given birth, due to the damage during delivery, the external os of the cervix becomes a horizontal or irregular slit. This gap divides the external cervical os into the anterior and posterior cervical lips.

The cervix is ​​mainly composed of connective tissue, with a small amount of smooth muscle fibers and rich blood vessels. The endometrium of the cervical canal is a layer of tall columnar epithelium, and the surface of the cervix that extends into the vagina is stratified squamous epithelium. There is a clear dividing line between the two types of epithelium, which is often a high-incidence site for cervical cancer.
