saphenous opening in the fascia lata, and 

 pierced in this situation by numerous 

 small bloodvessels and lymphatics, hence 

 the name cribriform fascia, which has been 

 applied to it. Subcutaneous bursa3 are 

 found in the superficial fascia over the 

 patella, point of the heel, and phalangeal 

 articulations of the toes. 



The deep fascia of the thigh is exposed 

 on the removal of the superficial fascia, 

 and is named, from its great extent, the 

 fascia lata ; it forms a uniform investment 

 for the whole of this region of the limb, 

 but varies in thickness in different parts ; 

 thus, it is thickest in the upper and outer 

 side of the thigh, where it receives a 

 fibrous expansion from the Gluteus maxi- 

 mus muscle, and the Tensor vaginae femoris 

 is inserted between i.ts layers ; it is very 

 thin behind, and at the upper and inner 

 side, where it covers the Adductor muscles, 

 and again becomes stronger around the 

 knee, receiving fibrous expansions from 

 the tendon of the Biceps externally, and 

 from the Sartorius, Gracilis, Semi-tendi- 

 nosus, and Quadriceps extensor cruris in 

 front. The fascia lata is attached, above, 

 to Poupart's ligament, and crest of the 

 ilium; behind, to the margin of the sa- 

 crum and coccyx ; internally, to the pubic 

 arch and pectineal line ; and below, to all 

 the prominent points around the knee- 

 joint, the condyles of the femur, tuberosi- 

 ties of the tibm, and head of the fibula. 

 That portion which invests the Gluteus 

 medius (the Gluteal aponeurosis) is very 

 thick and strong, and gives origin by its 

 inner surface, to some of the fibres of 

 that muscle ; at the upper border of the 

 Gluteus maximus, it divides into two 

 layers, the most superficial, very thin, 

 covering the surface of the Gluteus maxi- 

 mus, and is continuous below with the 

 fascia lata; the deep layer being thick above, 

 and blending with the great sacro-sciatic 

 ligament, thin below, where it separates 

 the Gluteus maximus from the deeper 

 muscles. From the inner surface of the 

 fascia lata, are given off two strong inter- 

 muscular septa, which are attached to 

 the whole length of the linea aspera ; the 

 external and stronger one, which extends 

 from the insertion of the Gluteus maximus, 

 to the outer condyle, separates the Vastus 

 externus in front from the short head of 

 the Biceps behind, and gives partial origin 

 to these muscles; the inner one, the
