Where is the cervix?

The position of the external cervical orifice in the vagina determines the type of uterine displacement. Generally, the normal posture of the uterus of adult women is to bend forward slightly. "inclination" refers to the relationship between the long axis of uterus and the long axis of vagina; "Flexion" refers to the relationship between the long axis of uterus and the long axis of cervix. Normal anteversion refers to the anteversion and approximately right-angle inclination of uterus and vagina; Normal flexion means that the uterus and cervix form a flexion angle of about 65438+070. The external cervix and two lips are in contact with the posterior vaginal wall. Due to various physiological or pathological factors, the included angle between "inclination" and "flexion" of uterus can change, which constitutes different types of uterine displacement: anterior displacement (forward, forward, forward and forward flexion), posterior displacement (backward, backward and horizontal) and lateral displacement (lateral, lateral, lateral and lateral flexion). I hope to adopt it as the best answer.
