Uterus and vagina (English)

The image above shows a coronal section of the female perineum. The inferior end of the cervix is seen projecting into the vagina, known as the vaginal part of the cervix. This protrusion forms a dome-shaped recess in the vaginal wall around the cervix called the vaginal fornix. The walls of the vagina are covered by many transverse folds called vaginal rugae, which contribute to the elasticity and resilience of the vagina during sexual intercourse. The vagina opens into the vestibule of vagina, a part of the vulva lying between the labia minora. The vagina is closely related to many organs and structures of the pelvic region. In this coronal section, one can observe its lateral relations with the paracolpium, left and right ureter and levator ani muscle. A part of the levator ani muscle, called the pubovaginalis muscle, provides a U-shaped muscular sling that wraps around the vagina.
