bones and the upper portion of the sacrum. The true pelvis is inferior and is surrounded by the pubis and ischium portions of the coxal bones, in addition to the lower sections of the ilium and the sacrum.

What separates the true and false pelvis?

An imaginary oblique line passing from the sacral promontory to the superior aspect of the symphysis pubis divides the pelvis into the false or greater pelvis superiorly and the true or lesser pelvis inferiorly.

What organs are true pelvis?

The pelvic cavity (the true pelvis) predominantly contains the urinary bladder, the colon, and the internal reproductive organs. This space is enclosed between the pelvic inlet and the pelvic outlet.
