THE LIMBS OF THE HOESE 



155 



The three, slightly converging, patellar ligaments (ligamenta patellae) 

 correspond to the single ligament of man and the dog. The lateral and 

 middle ligaments spring from the lateral and distal angles respectively 

 of the patella. The medial ligament is connected with the patellar 

 supplementary cartilage. The distal attachment of each band is to the 

 tuberosity of the tibia, the middle ligament being fixed to the distal 

 part of the groove-like depression of the tuberosity. 



The lateral ligament receives one of the insertions of the biceps

muscle and part of the fascia lata, while the medial ligament receives 

 the conjoint aponeurosis of the sartorius and gracilis. 



The patellar ligaments, strictly speaking, represent the tendon of 

 insertion of the quadriceps muscle of the thigh, the patella being a 

 sesamoid bone developed therein. 



The femoeo-tibial articulation (articulatio. femoro-tibialis). — A 

 rooinj joint-cajjside (capsula articularis), weak in front but strong behind 

 is attached to the articular margin of the tibial condyles and about 

 1 cm. from the margin of the condyles of the femur. Its fibrous layer 

 is also attached to the convex border of the interarticular cartilages 

 (medial and lateral menisci) and to the cruciate ligaments. The synovial
