 the external tuberosity of the tibia, and it becomes inserted by distinct

he superficial division should be cut at its point of attachment to the 

 tibial tuberosity, and dissected downwards, the difference of direction 

 serving to distinguish the fibres of the two divisions 



The Lu,rn<d Lateral Ligament is, like the precedino- a composite liga-
