The greater pelvis is also known as the false pelvis, which is a part of the pelvis that is above the pelvic brim. The pelvic brim is a circular edge that separates the greater pelvis from the lesser pelvis. The greater pelvis is responsible for supporting the weight of the upper body and transmitting it to the lower limbs. There are several synonyms for the greater pelvis, including the superior pelvis, the inlet pelvis, and the upper pelvic aperture. The term false pelvis is also frequently used to refer to the greater pelvis, as it does not house the pelvic organs but rather supports and transfers the weight of the body.
