Fascia lata (posterior half) 

 (see also Figs. 381, 382 and 

 389) is, upon the posterior 

 surface of the m. glutaeiis 

 maximus , in general thin ; 

 distalward it is somewhat 

 thicker. Interwoven in the 

 fascia , along the lateral sur- 

 face, from the lower end of 

 the m. tensor fasciae latae.on, 

 is a broad, thick, glistening, 

 tendinous strip of parallel 

 fibers, the tractus iliotibialis 

 [Maissiati] (0. T. iliotibial 

 band), which is attached below 

 to the condylus laterahs tibiae. 

 This strip consists above (see 

 Fig. 382) of a deep layer, 

 which is the direct con- 

 tinuation of the tendinous 

 fibers of the m. glutaeus 

 maximus, and of a superficial 

 layer, which consists partly 

 of tendinous fibers of the m. 

 tensor fasciae latae, partly 

 of fibers which descend from 

 the thick fascial covering of 

 the m. glutaeus medius. From 

 the latter region comes also 

 a thicker, flat bundle which 

 crosses the insertion of the 

 m. glutaeus maximus and 

 extends in a curve from above 

 downward and modianward 

 to the tuber ischiadicum. 

 This strand, cutting deep intii 

 the muscle, corresjionds to the 

 sulcus glutaeus (O.T. gluteal 

 groove), which is visible as a 

 furrow, running transversely 

 in the skin when the m. glu- 

 taeus maximus is relaxed. 

 A less marked strengthening 

 band, in the pupliteal space, 

 extends fr<im above and la- 

 teralward downward and me- 

 dianward and corresponds 

 also to a similarly directed 

 furrow in the skin. 

 Arising from the fascia lata are septa of connective 

 tissue which extend between the individual muscles 

 and gi-"U])s of muscles; the strongest of these pass 

 beliind the origins of the mm. vastus niedialis an<l 

 vastus lateralis to tht> iahiuui uiediale and labium laterale of the linea aspera femoris, forming 

 the septuin intermuscidai c /fo/ioris] riwdialc and septum intermusculare [femoris] laterale 

 (see Fig. 387): they serve ]irtly fur tln' attachment of the neighboring muscles.
