separates the tendon of the 

 muscle from the surface oi' 

 the trochanter in front of its 

 insertion. 



Relations. By its superfi- 

 cial surface, with the Gluteus 

 maximus behind, the Tensor 

 vaginae femoris and deep fas- 

 cia in front. By its deep 

 surface, with the Glutens mi- 

 nimus and the gluteal vessels 

 and nerve. Its anterior bor- 

 der is blended with the Glu- 

 teus minimus. Its posterior 

 border lies parallel with the 

 Pyriformis, the gluteal vessels 

 intervening. 



This muscle should now be divided 

 near its insertion and turned up- 

 wards, when the Gluteus minimus 

 will be exposed. 



The Gluteus Minimus, the 

 smallest of the three glutei, 

 is placed immediately beneath 

 the preceding. It is fan- 

 shaped, arising from the outer 

 surface of the ilium, between 

 the middle and inferior curved 

 lines, and behind, from the 

 margin of the great sacro- 

 sciatic notch; the fibres con- 

 verge to the deep surface of 

 a radiated aponeurosis, which, 

 terminating in a tendon, is 

 inserted into an impression 

 on the anterior border of the 

 great trochanter. A synovial 

 bursa is interposed between 

 the tendon and the great tro- 

 chanter. 



Relations. By its superfi- 

 cial surface, with the Gluteus 

 medius, and the gluteal vessels 

 and nerve. By its deep sur- 

 face, with the ilium, the re- 

 flected tendon of the Eectus 

 femoris, and capsular liga- 

 ment of the hip-joint. Its 

 anterior margin is blended 

 with the Gluteus medius. Its 

 posterior margin is often 

 joined with the tendon of the 

 Pyriformis. 



The Pyriformis is a flat 

 muscle, pyramidal in shape, 

 lying almost parallel with
