MUSCLES 53 



to inner condyle(p). Posterior part. Tubercle above inner 

 condyle(x) (Posterior division of obturator, Great sciatic). 

 [Adducts thigh ; rotates thigh out ; posterior fibres extend hip- 

 joint.] Between the two parts of the muscle there is an interval, the 

 femoral opening, which transmits the femoral vessels. 



HUNTER'S CANAL. Extends from the apex of Scarpa's 

 triangle to the opening in the adductor magnus, containing 

 the superficial femoral vessels and long saphenous nerve. It 

 is formed by aponeurotic fibres passing from the adductores 

 magnus and longus to the vastus internus, and is covered by 

 sartorius. 



GLUTEAL REGION. 



Gluteusmaximus : external surface of ilium between superior 

 curved line and posterior of outer lip of crest, aponeurosis 

 over erector spinae, posterior surfaces of coccyx, and of 

 last 2 pieces of sacrum, and great sacro sciatic ligament(F) 

 gluteal ridge between linea aspera and great trochanter(AF), 

 fascia lata^F) (Inferior gluteal). [A, extensor and rotator out- 

 wards of thigh ; B, after stooping, extends trunk on thigh.] 



Parts beneath the glutens maximus : part of gluteus mediua 

 the pyriformis, superior and inferior gemelli, tendon of 

 obturator internus, quadratus femoris, upper part of adductor 

 magnus, origins of semi-membranosus, semi-tendinosus, and 

 biceps and part of vastus externus. Superficial branch of 

 gluteal artery and superior gluteal nerve, sciatic vessels, and 

 great and small sciatic nerves, internal pudic vessels and pudic 

 nerve, nerve to obturator internus, inferior gluteal nerve, 

 branches of external and internal circumflex and ist per- 

 forating arteries. Three bursae, one over great trochanter, 

 one over tuber ischii, one over vastus externus. Great sacro- 

 sciatic ligament. Great trochanter and tuber ischii. 



Gluteus medius : bone between iliac crest and superior 

 curved line above, and middle curved line below, fascia(p) 

 outer surface of great trochanter from tip posteriorly to 

 base anteriorly(p) (Superior gluteal). [Extends and abducts 

 thigh : anterior fibres rotate thigh inwards, posterior out- 

 wards.] Conceals gluteal vessels and nerve. 



Gluteus minimus : posterior surface of hip-bone between 

 middle and inferior curved lines(p) impression on anterior 

 part of great trochanter(p) (Superior gluteal). [Abducts and 

 rotates thigh inwards.] 



Pyriformis : anterior surface of sacrum, from 2nd, 3rd, and 

 4th pieces between anterior foramina, upper margin of great 

 sciatic notch, great sacro-sciatic ligament(p) posterior part
