G. Muscles of the Inferwor Hatremities. 
Kach inferior extremity is connected to the trunk by the strong ligaments 
of the hip joint, and by several muscles which pass 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- 
tei, the pyriformis, the gemini, the two obturators, and the quadratus 
femoris. | 
Gluteus maximus covers the greater part of the pelvis, also the upper. 
part of the thigh; it is somewhat square, with the inferior edge thick and:
