What is anteversion
Where the long axis of the uterus bends forwards on the long axis of the vagina
What is antiflexion
Where the long axis of the uterus bends forwards at the internal os with the long axis of the vagina
What supplies blood to the uterus
Ovarian, uterine, vaginal and internal pudendal arteries
What are the ovaries involved in
Ova and hormone production
What are the ovaries attached to
