muscle and the fascia lata ; extending from the anterior superior spine of 

 the ilium to the spine of the pubic bone. 



FIG. 47. Tensor Vaginae Femoris, 4 from the anterior part of 



the outer lip of the iliac crest, and the anterioi 

 superior spinous process, into the fascia lata later- 

 ally, for one-fourth down the thigh. Action, a 

 tensor of the fascia lata. Nerve, superior gluteal. 



Sartorius, 5 from the anterior superior spine of the 

 ilium 2 and half of the notch below it, into the 

 upper internal surface of the shaft of the tibia. 

 Action, to flex and cross the legs. Nerve, anterior 

 crural. 



Quadriceps Extensor, includes the rectus, vastus 

 internus and externus, and the crureus muscles. 

 Its tendon contains the patella. 



Rectus Femoris, 6 by two tendons, the Straight from 

 the anterior inferior spine of the ilium, the Reflected 

 from a groove above the brim of the acetabulum, 

 into the tuberosity of the tibia by the tendon 9 

 common to this and the next 3 muscles. Action, to 

 extend the leg. Nerve, anterior crural. 



Vastus Externus, 7 from the anterior border of the 

 great trochanter and the whole length of the linea 

 aspera, into the tuberosity of the tibia, by the 

 common tendon. 



Vastus Internus 8 and Crureus are one muscle, arising 

 from the inner lip of the linea aspera and nearly 

 the whole of the shaft of the femur in front and 

 laterally from the trochanters down to within the 

 lower one-fourth of the bone, into the tuberosity of the tibia by the common 

 extensor tendon. Action, to extend the leg. Nerve, anterior crural. 



Subcrureus, from the lower part of the femur anteriorly, into the synovia! 



pouch behind the patella. Action, to draw up the synovial sac. Nerve, 



anterior crural. 

 Gracilis, 15 /h?w the inner margin of the rami of the pubes and ischium, into 



the inner surface of the shaft of the tibia below the tuberosity. Action, to 



flex and adduct the leg. Nerve, obturator. 

 Pectineus, 12 from the ilio-pectineal line, and the bone in front thereof, also 



from an expansion of Gimbernat's ligament, into the rough line extending
