process, and is inserted between two layers of the fascia lata at about 

 one -fourth down the thigh. 



Relations. By its superficial sur- 

 face with the fascia lata and integu- 

 ment. By its deep surface with 

 the internal layer of the fascia lata, 

 gluteus medius, rectus and vastus 

 externus. By its inner border, near 

 its origin with the sartorius. 



The SARTORIUS (tailor's muscle) 

 is a long riband-like muscle, arising 

 from the anterior superior spinous 

 process of the ilium, and from the 

 notch immediately below that pro- 

 cess ; it crosses obliquely the upper 

 third of the thigh, descends behind 

 the inner condyle of the femur, 

 and is inserted by an aponeurotic 

 expansion into the inner tuberosity 

 of the tibia. This expansion covers 

 in the insertion of the tendons of 

 the gracilis and semitendinosus 

 muscles. The inner border of the 

 sartorius muscle is the guide to 

 the operation for tying the femoral 

 artery in the middle of its course. 



Relations. By its superficial sur- 

 face with the fascia lata and some 

 cutaneous nerves. By its deep sur- 

 face with the psoas and iliacus, 

 rectus, sheath of the femoral vessels 

 and saphenous nerves, vastus inter- 

 nus, adductor longus, adductor mag- 

 nus, gracilis, long saphenous nerve, 

 internal lateral ligament of the 

 knee-joint. By its expanded in- 

 sertion with the tendons of the 

 gracilis and semitendinosus, a syno- 

 vial bursa being interposed. At 

 the knee-joint its posterior border 



is in relation with the internal saphenous vein. At the upper third 

 of the thigh the sartorius forms, with the lower border of the adductor
