Position & Fixation[✎ edit | edit source]

Uterus and vagina in anteflexion and anteversion

The uterus is normally anteverted and anteflexed, so its weight is lying on top of the urinary bladder. When bladder or rectum fills, its position changes accordingly.

It receives passive and active support:

  • Actively:
    1. by the broad ligament of uterus;
    2. by the cardinal ligament extends from the cervix and lateral parts of the vagina to the lateral walls of pelvis, thus keeping the axis in place.
  • Passively:
    1. by the pelvic diaphragm;
    2. via the way it is anteflexed and anteverted, thus resting on the bladder.

Supply:[✎ edit | edit source]

Arterial supply from uterine artery. Anastamoses with ovarian artery Autonomically innervation from Inferior Hypogastric plexus Lymph Drainage to Internal Iliac lymph nodes, though the cervix in some texts is thought to have its drainage to the superficial inguinal nodes Venous drainage is by uterine veins.
