The arrangements by which the uterus is supported are of importance to the understanding of the displacements of the organ. In the virgin the vagina forms a tolerably solid column, on the summit of which the uterus is supported and so prevented from descending. The vagina is also attached, by means of the pelvic fascia, to the bladder in front and the peritoneum behind. The uterus is further supported by its ligaments, and these, especially the round ligament, assist in preventing its descent, although not so directly as the vagina. As ligaments pass off from its lateral aspects, the uterus is kept from inclining to one side or the other. While capable of very limited movement from above downwards and from side to side, the body of the uterus is very movable, within certain limits, from before backwards. When the bladder and rectum are full the uterus will be tolerably erect. When the bladder is empty it will be inclined forward, and a certain amount of anteversion may be regarded as the normal condition with an empty bladder.
