G. Muscles of the Inferior Extremities. 



Each inferior extremity is connected to the trunk bj the strong ligaments 

 of the hip joint, and by several muscles which pas's from the pelvis to the 

 thigh and leg. The muscles of the lower extremities may be conve- 

 niently classed into those of the pelvis or hip joint, thigh, leg, and foot; 

 those of the thigh are arranged into posterior, anterior, external, and 

 internal. 



1. Muscles of the Hip. These are nine in number : the three glu- 

 taei, the pyriformis, the gemini, the two obturators, and the quadratus 

 femoris. 



Olutcens maximtis covers the greater part of the pelvis, also the upper 

 part of the thigh ; it is somewhat square, with the inferior edge thick and
