is the ilium the same as the iliac
The iliac crest is the curved superior border of the ilium, the largest of the three bones that merge to form the os coxa, or hip bone. It is located on the superior and lateral edge of the ilium very close to the surface of the skin in the hip region. When a person places their hands on their hips, it is the skin above the iliac crest that they rest their hands on.
