Detailed diagram of the location of the posterior fornix

Many women don't know their bodies very well, especially some of the more private areas. So when there is a problem in this area, we still don’t know where it actually is. It refers to the area in the female vulva called the posterior fornix of the vagina. However, many women are not very familiar with this position. The following is a detailed diagram of the location of the posterior vaginal fornix.

Detailed map of the posterior vaginal fornix

The vagina is located between the bladder, urethra and duodenum, and is a highly extensible tubular organ. It has a variety of physiological functions in the human reproductive process. It is the passage connecting the uterus and private parts, the only way for the discharge of menstrual blood and the birth of the baby, and it is also an important sexual organ.

Normally, the front, back, left and right walls of the vagina are close to each other so that the cross section is in the shape of an "H". The upper part bends downward and backward, close to the sacral concave, and the lower part bends forward, making the sagittal plane inside the vagina "S" shape. The upper part of the vagina is spacious and tightly surrounds the cervix. The annular cavity between the cervix and the vaginal wall is called the vaginal vault. According to its position, it is divided into four parts: front, back, upper and lower. The posterior vaginal fornix is ​​very deep and wide as a sperm reservoir. In the laparoscopic position, the posterior vaginal fornix is ​​the lowest point in the vagina. This anatomical relationship is conducive to the flow of sperm from the vagina to the cervix, because the external os of the cervix in a normal position faces the posterior vaginal fornix. The posterior fornix is ​​the part of the vagina that is easily dilated. It provides the necessary space for the erect penis and prevents excessive movement of the cervix and possible sexual difficulties.

The upper part of the vagina is wider than the lower part, with the back wall about 10 to 12 cm long and the front wall about 7 to 9 cm long. The average size of the vagina is about 7.5 cm from the opening to the cervix. The upper part of the vagina is spacious and tightly surrounds the cervix. The annular space between the cervix and the vaginal wall is called the vaginal vault. When harmful bacteria enter the vaginal vault and cervix, vaginitis will occur.

At this time, the problem cannot be solved by relying on nitrogen circulation in the vagina. You need to use a lotion, preferably one that can reach deep into the vaginal vault and cervix. The length of the hose is determined according to the characteristics of the female body, which can greatly improve the inflammation of the vault area. For example, the patented eight-hole nozzle used in vaginal cleansing liquid can ensure deep penetration into the vaginal vault and cervix.

I believe that many women will have a deeper understanding of their own bodies after mastering it, so that if problems arise in future daily life, we will know how to deal with them. I no longer feel embarrassed about not knowing the position of my own body.
