I02 ELEMENTS OF MAMMALIAN ANATOMY 



(6i) Sartorius (Fig. 51); crest and ventral border of ilium to 

 ligament of petalla and adjacent crest of the tibia; abductor and 

 rotator of thigh and extensor of shank. 



(62) Gluteus medius; ilium and fascia at root of tail to 

 greater trochanter of femur; abductor of thigh (Fig. 50). 



(63) Pyrifonnis ; last two sacral and first caudal vertebriE to 

 greater tuberosity of femur; abductor of thigh (Fig. 51). 



(64) Gemellus superior; dorsal border of ilium and ischium 

 to greater trochanter of femur; rotator and abductor of thigh. 



(65) Gluteus minimus; ventral half of ilium to greater 

 trochanter of femur; rotator of thigh (Fig. 51). 



(66) Obturator intemus; ischium to trochanteric fossa of 

 femur; abductor of thigh (Fig. 51). 



(67) Gemellus inferior; lateral surface of ischium to inner 

 surface of the tendon of obturator internus and to capsule of 

 joint; abductor of thigh (Fig. 51). 



(68) Gracilis (Fig. 57); ventral aspect of ischiopubal sym- 

 physis to shaft of tibia; adductor of thigh. 



(69) Semitendinosus (Fig. 50) ; ischial tuberosity to the crest 

 of the tibia; flexor of shank; subcylindrical muscle of the inner 

 hamstring group. 



(70) Semimembranosus (Figs. 49, 50); ischium to medial 

 epicondyle of femur and proximal end of tibia; extensor of 

 thigh; largest of inner hamstring group. 



(71) Adductor femoris {magnus et brevis) (Figs. 49, 50); 

 ischiopubal symphysis to shaft of femur; extensor of thigh. 



(72) Quadratus femoris; ischial tuberosity to great tro- 

 chanter and adjacent surface of lesser trochanter of femur; 

 extensor and rotator of thigh (Fig. 51). 



(73) Obturator extemus; obturator foramen and adjacent 

 parts of pubis and ischium to trochanteric fossa of femur; 

 rotator and flexor of thigh (Fig. 50). 



(74) Adductor longus (Fig. 49); cranial border of pubis to 

 middle of femur.
