What are coxal bones?
Commonly referred to as your hipbones, the two major bones in your pelvis are your coxal bones.

What are the three different parts of the coxal bone?
The pelvic girdle consists of a pair of hip bones, also known as the coxal bones. Each bone is made up of three individual bones that fuse together over the first 20 years of life. These bones are known as the ilium (IL-e-um; plural, ilia), ischium (ISH-e-um, ischia), and pubis (PU-bis).
