Frontal section through the same. Posterior half of section, 



viewed from in front. 



(The joint surfaces have been somewhat pulled apart.) 



Articulatio coxae (continued). Its capsula articularis arises at the margin of the 

 acetabulum, chiefly outside the labrum glenoidale so that this lies more or less completely within 

 the joint cavity. The capsule is attached to the femur in front close above the linea inter- 

 trochanterica, behind to the neck of the femur medianward from the crista intertrochanterica in 

 a line parallel to the latter so that somewhat more than the medial half of the posterior surface 

 of the neck of the femur looks into the joint capsule. The stratum synoviale of the capsule 

 is continued upon the ligamentum teres and encloses this like a sheath. The fossa acetabuli 

 is almost completely filled up by masses of fat, synovial villi and the ligamentum teres.
