covering the glutaeus medius. It extends distally, with a 

 slight inclination posteriorly, and is inserted into the ilio- 

 tibial tract of the fascia lata. 



Arteria Circumflexa Femoris Lateralis (O.T. External 

 Circumflex Artery). The lateral femoral circumflex artery is 

 the largest branch which springs from the profunda femoris 

 artery. It arises near the origin of the latter, and runs 

 laterally, between the divisions of the femoral nerve and then

under cover of the sartorius, to the deep surface of the rectus 

 femoris muscle, where it ends by dividing into ascending, 

 transverse, and descending branches. 



The ascending branch reaches the external surface of the 

 upper part of the ilium by ascending along the inter- 

 trochanteric line of the femur under cover of the deep surface 

 of the tensor fasciae latse. As it ascends it gives a branch to 

 the hip joint, twigs to the adjacent muscles, and its terminal 

 twigs anastomose with branches of the superior gluteal artery.
