THE LIMBS OF THE HOKSE 



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. 

 TThe lateral ligament receives one of the insertions of the biceps
