How does the pelvic brim divide the pelvis?

The pelvic brim divides the pelvis (from the Latin, meaning “basin”) into the false or greater pelvis and the true or lesser pelvis. The part of the pelvis above the pelvic brim is the false pelvis. It does not contain any pelvic organs, except for the urinary bladder, when it is full, and the uterus during pregnancy. The part of the pelvis below the pelvic brim is the true pelvis. The pelvic inlet is the upper opening of the true pelvis, and the pelvic outlet is the lower opening of the true pelvis.
