Muscles of the 

 right thigh, 



viewed from in front. 



Fascia lata (continued). 

 The fossa bounded by the 

 marii^o falciformis is called 

 the fossa ovalis; it is covered 

 by the fascia cribrosa, a deep 

 layer of the fascia super- 

 ficialis which extends from 

 the margo falciformis to the 

 fascia pectinea and presents 

 openings for lymph glands 

 and vessels. The space fi'om 

 the annulus femoralis as far 

 as the entrance to the fossa 

 ovalis is called also the 

 canalis femoralis.

Bui'sa iufrapatellaris 

 subcutauea (see Fig. 375), 

 frequently present, just be- 

 neath the skin, in front of 

 the lig. patellae. 



Bursa siibeutanea tu- 

 berositatis tibiae (see Fig. 

 3T5), frecjuently present, in 

 front of the tuberositas tibiae. 



M. sartorius (see also 

 Fig. 388). F r m : flat, narrow, 

 very long. Position: super- 

 ficial, in a long spiral above 

 on the anterior, below on 

 the medial surface of the 

 thigh. Origin: by a short 

 tendon from the spina iliaca 

 anterior superior. Inser- 

 tion: the fibers run parallel, 

 at first medianward and 

 downward in front of the 

 ra. iliopsoas and in front of 

 the groove l)etween the m. 

 (puulriceps and the adductors, 

 then downward medial from 

 the m. vastus mediahs in front 

 of the m. gracilis, then be- 

 hind thf- epicondylus medialis, 

 and thence obliquely forward 

 with a flat, diverging tendon 

 to the tubei-ositas tibiae and 

 fascia cruris; the tendon 

 covers the insertions of the 



mm. gracilis and semitendinosus and fuses with 

 (bursa m. sartorii propria see Figs. 377 and 

 Action: it flexes the thigh a'i the hip -joint and the leg 

 at the knee, at the same time rotating the leg mward 

 and the flexed thigh outward. Innervation: n.femorahs.
