Final answer:
The false pelvis, or greater pelvis, is located above the pelvic inlet and contains abdominal organs. The true pelvis, or lesser pelvis, is situated below the pelvic inlet and encompasses the pelvic outlet.
Step-by-step explanation:
The false pelvis (also called greater pelvis) is above the pelvic inlet and surrounded by abdominal organs. The true pelvis (also called lesser pelvis) is below the pelvic inlet and has the opening of the pelvic outlet.
The pelvic brim (also known as the pelvic inlet) separates these two regions, with the greater pelvis positioned superiorly and the lesser pelvis located inferiorly. The greater pelvis provides space for portions of the intestines, while the lesser pelvis contains the bladder and other pelvic organs. Unique anatomical features like the pelvic inlet shape and the subpubic angle are essential in differentiating between male and female pelves, especially for childbirth adaptation in females.
