64 HUMAN ANATOMY. 



don, its outer surface smooth for the passage of the gluteus maxi- 

 mus tendon, separated by a bursa, and its superior surface marked 

 by three impressions, from behind forward, for pyriformis, obtu- 

 rator internus,' and gemelli muscles. The gluteus minimus is 

 attached to the anterior border; 



Digital or trochanteric fossa, to the inner side of the great 

 trochanter, for insertion of obturator externus tendon ; 



The lesser trochanter, a small, conical projection at the base 

 of the neck posteriorly, and giving attachment to the tendon 

 of psoas magnus muscle, the iliacus being inserted below ; 



Anterior intertro chant eric line, connects the trochanters in 

 front and gives attachment at its upper part to the capsular liga- 

 ment; 



Posterior intertrochanteric line, a much more prominent 

 ridge, connects them behind ; 



Tubercle of the femur, a prominence at the junction of the 

 neck with the great trochanter, is the meeting-place of five mus- 

 cles two gemelli, obturator internus, gluteus minimus, and 

 vastus externus; 



Tubercle of the quadratus, about the centre of the posterior 

 intertrochanter line, for the quadratus femoris; 



Linea quadrati, passes vertically downward from the middle 

 of the posterior line, and gives attachment to part of adductor 

 magnus and quadratus femoris. 



The inferior extremity, large and cuboidal in form, pre- 

 sents :-. 



External condyle, shorter and broader than the internal, has 

 behind its centre the outer tuberosity for the external lateral liga- 

 ments of the knee, and a groove below the tuberosity for the 

 tendon of the popliteus muscle. It also gives origin to the outer 

 head of the gastrocnemius, above which arises the plantaris mus- 

 cle; 



The internal condyle, longer by half an inch and more 

 prominent (so as to bring them on the same horizontal plane 

 owing to the obliquity of the shaft) , has on the inner surface the 

 inner tuberosity for the internal lateral ligament; 



Adductor tubercle, at the summit of the internal condyle, 

 marks the termination of the inner ridge of the linea aspera, and 

 gives attachment to tendon of adductor magnus ; 



Depression, above the articular surface of the internal con- 

 dyle posteriorly, for the origin of the inner head of gastrocne- 

 mius; 



Inter condyloid notch, separates the condyles behind, and 

 lodges the crucial ligaments;
