Cervix
Updated:The cervix is a crucial part of the female reproductive system, located at the lower end of the uterus where it meets the vagina. This cylindrical, donut-shaped structure acts as a gateway between the uterus and vagina, playing vital roles in menstruation, pregnancy, and childbirth. The cervix is typically 3-4 centimeters long and made up of strong, fibrous tissue.
Additional Information
The cervix has several important functions:
- Menstruation: It allows menstrual blood to flow from the uterus into the vagina.
- Fertility: During ovulation, it produces cervical mucus that helps sperm travel to the uterus.
- Pregnancy: It forms a mucus plug to protect the developing fetus from infections.
- Childbirth: It dilates to allow the baby to pass through during delivery.
The cervix also changes throughout the menstrual cycle and can be an indicator of overall reproductive health. Regular cervical screenings, such as Pap smears, are essential for detecting early signs of cervical cancer or other abnormalities.
Examples
During a gynecological exam, the doctor may examine the cervix using a speculum.
Some people can feel their cervix with their fingers during self-examination, noting its position and texture changes throughout their menstrual cycle.
