fibrous expansions from the tendons of the Biceps femoris externally, from the 

 Sartorius internally, and from the Quadriceps extensor in front. The fascia lata 

 is attached above, and behind, to the back of the sacrum and coccyx; externally, 

 to the crest of the ilium; in front, to Poupart's ligament and to the body of the os 

 pubis; and internally, to the descending ramus of the os pubis, to the ramus and 

 tuberosity of the ischium, and to the lower border of the great sacrosciatic ligament. 

 From its attachment to the crest of the ilium it passes down over the Gluteus 

 medius muscle to the upper border of the Gluteus maximus, where it splits into 

 two layers, one passing superficial to and the other beneath this muscle. At the 

 lower border of the muscle the two layers reunite. Externally the fascia lata 

 receives the greater part of the tendon of insertion of the Gluteus maximus, and 

 becomes proportionately thickened. The portion of the fascia lata arising from 

 the front part of the crest of the ilium, corresponding to the origin of the Tensor

fasciae femoris, passes down the outer side of the thigh as two layers, one super- 

 ficial to and the other beneath this muscle. These layers at the lower end of the 

 muscle become blended into a thick and strong band, having first received the 

 insertion of the muscle. This band is continued downward, under the name of 

 the iliotibial band (tractus iliotibialis [Maissiati]), to be inserted into the external 

 tuberosity of the tibia,. Below, the fascia lata is attached to all the prominent 

 points around the knee-joint viz., the condyles of the fernur, tuberosities of 

 the tibia, and head of the fibula. On each side of the patella it is strengthened 

 by transverse fibres given off from the lower part of the Vasti muscles, which are 

 attached to and support this bone. Of these, the outer fibres are the stronger, 

 and are continuous with the iliotibial band. From the deep surface of the fascia 

 lata are given off two strong intermuscular septa, which are attached to the whole 

 length of the linea aspera and its prolongations above and below; the external
