When we were in nursery school we called the acetabulum the hip joint. It is on the lateral side of the os coxa. The ilium, ischium, and pubis all form part of the acetabulum. This is a ball and socket joint where the head of the femur articulates with the acetabulum. It allows for flexion, extension, abduction, adduction, and rotation. The name translates to mean "a vinegar cup". I am not sure who named it that, but we should be looking into what they were smoking at the time!
