Bone, Os femoris, from before. 



The upper extremity of 

 the femur consists of a head, 

 Caput femoris, which is connected 

 to the shaft by means of a neck, 

 and has a small depression, 

 Foveola, for the insertion of the 

 Lig. teres. At the place where 

 the neck is continued into the 

 shaft, are the two t r o chanters, 

 the great external, Trochanter 

 major , and the lesser inter- 

 nal, Trochanter minor,- these are 

 connected by the two inter- 

 tro chant eric lines, the Linea 

 intertrochanterica anterior and pos- 

 terior. At the internal surface of 

 the great trochanter lies the digi- 

 tal or trochanteric fossa, Fossa 

 trochanterica (Fig. 166). 



The Linea ospera femoris 

 (Fig. 166) extends along the 

 posterior surface of the 

 shaft 5 it presents two lips, 

 Labia. 



The lower extremity 

 presents two condyles, Condy- 

 lus externus and Condylus interims, 

 each of which has a tuberosity. 

 The condyles are separated 

 posteriorly by the intercondyloid 

 notch or Fossa poplitea (Fig. 166). 



The femur articulates with 

 three hones: the Os innominatum, 

 tibia and patella.
