Uterus and vagina (Latin)

The image above shows a coronal section of the female reproductive system. We can locate the uterus superiorly, and the vagina with its anterior wall removed inferiorly. The inferior end of the cervix is seen projecting into the vagina, known as the portio vaginalis cervicis. This protrusion forms a dome-shaped recess in the vaginal wall around the cervix called the fornix vaginae. The walls of the vagina are covered by many transverse folds called rugae vaginales, which contribute to the elasticity and resilience of the vagina during sexual intercourse. The vagina opens into the vestibulum vaginae, a part of the vulva lying between the labium minus pudendi. 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, ureter dexter and sinister, and m. levator ani. A part of the m. levator ani, called the m. pubovaginalis, provides a U-shaped muscular sling that wraps around the vagina.
