SECT. II. MUSCLES OF THE THIGH. 



The Tensor Fascia vel Vagince Femoris, 



Is situated superficially on the anterior outer part of the hip. 

 It arises, tendinous, from the anterior superior spinous process 

 of the ilium; passes downwards and somewhat backwards be- 

 tween two lamina? of the fascia femoris, increasing in breadth 

 as it descends; and is inserted fleshy into the fascia femoris, 

 somewhat below the level of the trochanter major. 



It rotates the foot inwards, and makes the fascia tense. 



The Sartorius, 



Is placed superficially on the internal side of the thigh. It 

 arises by a short tendon from the anterior superior spinous pro- 

 cess of the ilium, and passes in a spiral course to the inner side 

 of the thigh and to the back of the internal condyle. It then 

 winds behind the head of the tibia, and advances forwards so as 

 to be inserted into the internal side of the lower part of its tu- 

 bercle by a broad tendon. Its fibres run the whole length of 

 the muscle. 



Its tendon is continued by a flat slip from its lower margin 

 into the fascia cruralis, by which attachment the muscle is held 

 in its spiral course. It crosses the rectus femoris and vastus in- 

 ternus above, the triceps adductor at the middle of the thigh, 

 and at the lower part of the latter, just above the knee, it is be- 

 tween the tendon of the adductor magnus and that of the gra- 

 cilis. 



It bends the leg and draws it obliquely inwards.* 



The Rectus Femoris, 



Is in front of the thigh bone and just beneath the fascia femo- 

 ris, with the exception of its origin, which is covered by the 



* Varieties. Sometimes a small fasciculus is detached from its inferior part; 

 sometimes its fibres are interrupted by a middle tendon which adheres closely to 

 the fascia femoris. Meckel reports it as deficient in one case that he met with. 

 In the African I have occasionally seen it unusually broad.
