What is the name of the structure that the pelvic bones create?

The pelvic bones are a group of bones in the lower torso that form the pelvis. They serve as a supporting structure for the spine and legs. 

The pelvic bones, also known as hip bones, combine to form the bony pelvis or pelvic girdle, a complex structure. It is made up of two hip bones (os coxae), a sacrum, and a coccyx (tailbone). 

The bony pelvis acts as a support structure for the lower spine and legs, as well as a sturdy framework for the muscles and ligaments that allow hip and leg movement. 

It also serves as a protective cavity for the lower abdomen's internal organs, such as the bladder, reproductive organs, and a portion of the large intestine.
