Uterus and Vagina

Description

Anterior pelvic anatomy centers on an anteflexed uterus positioned superior to the vaginal canal, with the fundus directed anterosuperiorly and the cervix projecting inferiorly into the vaginal fornices. The uterine body lies proximal to the cervix, while the vagina extends inferiorly toward the introitus in line with the birth canal. Cervical orientation in this posture creates the typical uterocervical angle, with the vaginal axis more posteroinferior than the uterine axis. Anteflexion and cervical position matter when you are teaching pelvic exam technique or correlating symptoms with uterine version and flexion. A retroverted or less flexed uterus can change bimanual exam findings and affects the trajectory for uterine sounding, intrauterine device insertion, and dilation and curettage. Labor and delivery also depend on this geometry, since the cervix must efface and dilate to align the uterine cavity with the vaginal canal during birth. Use this artwork in gross anatomy and obstetrics and gynecology curricula to anchor terminology such as uterus, cervix, and vagina, and to contrast normal relationships with common variants. It also fits patient education materials and textbook figures explaining pelvic examination, IUD placement, and the functional pathway of the female reproductive tract.
