Fascia of 

 the right thigh, 



viewed from in front. 



Fascia lata [anterior lialf| 

 (see also Fios. 325 and 372) 

 covers the free surface of the 

 muscles of the thigh and is 

 stronger lateralward and above. 

 From near the knee a fibrous 

 process runs upward and lateral- 

 ward : a furrow in the skin 

 corresponds to this when the 

 knee is extended and the muscles 

 are relaxed. The fascia also 

 forms a sheath for the m. sar- 

 torius behind and dindes above 

 into a deep and a superficial 

 layer. The deep layer covers 

 the fossa iliopecliuea. This (see 

 Figs. 372 and 376) possesses a 

 triangular entrance, comes in 

 ri^ation above with the lig. ingui- 

 nale and ends below under the 

 m. sartorius; lateralward it is 

 bounded by the m. iliopsoas, 

 medianwanl by the m.pectineus: 

 above it is continued into the 

 lacima vasoriun. It is the lateral 

 part of the larger, triangular, 

 trigoimm femorale [fossa Scar- 

 pae major] ((). T. Scarpa's tri- 

 angle), which is limited above 

 by the hg. inguinale, laterally 

 by the m. sartorius, and me- 

 diauly l)y the medial edge uf the 

 m. adductor longus. Lateralward 

 the deep layer is identical with 

 the fascia iliopectinea (see p. 

 325), and medianward, upon 

 tlie m. pectineus, it is called the 

 fascia pec tinea. The super- 

 ficial layer partially covers 

 the fossa iliopectinea and passes 

 from the upper edge of the m. 

 sartorius to the lower edge of 

 the lig. inguinale. It ends median- 

 ward with a concave edge, margo 

 falciformis (0. T. falciform liga- 

 ment) which arises below from 

 the faseia pectinea (cornu in- 

 ferius), is often indistinctly 

 oiitliiUHl in its middle portion 

 and, above (cornu siiperius), 

 runs medianward to the lig. in- 

 iiiiLuale and the liii'. lacimare.
