152. The Right Hip Bone, Os innominatum, outer surface, 



with the insertions of the muscles. 



At the place where the ilium, ischium and pubes meet, the 

 acetabulum is situated (Fig. 150); its rim, the Sitpercilium acdabuli, 

 is interrupted by a notch, the Indsura acetabuli. The bottom of the cavity 

 of the acetabulum has a rough depression, free of cartilage, the Fossa 

 acetabuli, which is continuous with the incisura. 



Below the acetabulum is the large obturator foramen, Foramen 

 obturatum seu ovale.
