The acute process of the hipbone

The acute process (d in figs. 2, 3) [spina ischiadica] of the hipbone should also be observed here; it puts forth a ligament (o in the 13th table of muscles) [lig. sacrospinale] that extends to the transverse process (R in figs. 1, 2, ch. 18) [pars lateralis] of the fifth sacral bone, and it provides the origin for the muscle [m. gemellus superior] (x in the 13th table of muscles or b in the 12th, where the tenth muscle is marked a) [m. obturator internus] which we shall either ascribe to the tenth of the muscles that move the femur or number separately the eleventh.
