well-marked ridges superior, middle, and inferior which limit 

 the origins of the gluteal muscles. The internal surface of the 

 bone is divided into two parts the posterior part, which takes 

 up nearly half, is a rough auricular -shaped surface for 

 articulation with the sacrum ; while the anterior part, which is
