Under the uterus, which is joined to the upper end of the vagina (cervix Latin word that means “neck of the uterus” is,) is a small part it cervix. It is the end of the cylindrical or conical from the top of the anterior vaginal wall. Approximately half of its length, is displayed with an appropriate medical device, to lie above another vagina after inspection. Neck has an opening to move the inside, to allow menstrual fluid and sperm. Portion projecting into the vagina is ectocervix and portio vagina. As a whole, the ectocervix, is 2.5 cm wide and 3 cm. Has an elliptical surface convex, which is divided on the lips of the front and back.

Opening are called external OS is ectocervix. The size and shape of the ectocervix and the outer axle to change significantly age, hormonal status, or women whether had a vaginal delivery. External OS for women with vaginal birth looks like a small round hole. It appears bulky in women there was a vaginal delivery of ectocervix, wider, OS external, will be displayed with the gaping slit more. Epithelium of the cervix is ​​changing. It is composed of squamous epithelium layer nonkeratinized (more distant from the vagina) in the ectocervix. It is composed of a columnar epithelium simple (more proximal, within the uterus) in the cervix.

Border of the ectocervix and the cervix, also known as the squamocolumnar junction or transformation zone. Transformation zone undergoes metaplasia many times during the life of normal. When exposed to a harsh acidic environment of the vagina, exocervix undergoes metaplasia to squamous epithelium suitable for vaginal environment. Similarly, when the ectocervix enters the uterus, it is tough area to receive metaplasia to become columnar epithelium.

Is a water-cervical mucus, and 90%. Depending on the moisture content changes during the menstrual cycle of mucus acts as a transmission medium or barrier of sperm. (Calcium, sodium, potassium), for example, cervical mucus, which contains an organic compound as glucose, amino acids, and soluble protein electrolyte.

The cervical mucus, zinc, copper, manganese, iron, selenium, and trace elements, including the level of change in response to changes in the cyclic hormone in different stages of the menstrual cycle is included. different enzymes have been identified in human cervical mucus. Glycerol is a natural component of human cervical mucus. The study, the amount of glycerol 頸流 uterine body has been shown to increase during sexual excitement. It is estimated to be responsible for the lubricating properties of the fertile cervical mucus, increased glycerol, may be biologically important during the early stages of reproductive events.

After the menstrual period is completed, OS external thick, is cut off by the acidic mucus. After you enter the uterus, sperm mucus block “infertility” this. Within a few days, the ovulation time, production is “fertile” mucus species, they Yu high content of acidic electrolyte and less moisture content high. The electrolyte These cause a pattern of “fern” seen in drying fluid at low magnification fluid such as drying, as fern leaf, salt, crystallizes.

The several methods of fertility awareness, such as Billings and law Clayton model, to evaluate the period of female infertility and infertility treatment by observing the changes in your body contains. There are involved in a number of quality of cervical mucus, in these changes, vulva, its elasticity (spinnbarkeit) causes the transparency, the presence or absence of a fern-like crystals formed his senses. In order to prevent the kind of fertile mucus because it is produced, and a method of hormonal contraception work, their effectiveness is increased by preventing ovulation, mainly almost. Meanwhile, a method for thinning of mucus, can help you achieve pregnancy. It is that the method takes guaifenesin in a few days before ovulation, but one, was suggested. During pregnancy, it is possible to prevent infection during the infertility part of the menstrual cycle, the situation was somewhat similar, the cervix has been blocked by antibacterial mucosal plug specific. Or expand the cervix during childbirth, just before outside mucus plug.

After receiving the influence of estrogen directly with menstruation, we set the texture change the position of the cervix. The majority of the menstrual cycle, remains solid, as low as the tip of the nose, has closed the cervix. But ovulation approaches, it increases with neck, mouth, closer, softer, and estrogen presence in ovulation, the high level, female open. These changes will support the production of fertile types of cervical mucus, and movement of sperm survival together. Human papillomavirus (HPV) infection is a necessary factor in the development of almost all cases of cervical cancer. HPV vaccine, can reduce the likelihood of the occurrence of cervical cancer when administered prior to sexual activity. Potential changes in cervical cancer is scraped from the surface of the cervix epithelial cells can be detected by a Pap smear was examined under a microscope. With proper treatment, it is possible to prevent cervical cancer such knowledge. Cry had a Pap test, or that anyone had within the past 10 years most women who develop cervical cancer.
