 nerve and, it may be, the geniculate branch of the obturator nerve. 

 At the outer part of the ligament there is a«special opening for the 

 tendon of the popliteus. Another opening is frequently present 

 over the upper and back part of the inner condyle, and, when 

 this is so, the popliteal bursa between the semimembranosus and 

 the inner head of the gastrocnemius communicates with the 

 synovial membrane of the joint. The upper and outer part of

The external lateral ligament consists of two divisions — anterioi 

 and posterior. The anterior division is the proper external latera 

 ligament, and is known as the long external lateral ligament. It i 

 firm and cord-like, and passes vertically downwards, lying clear c 

 the joint. It is attached superiorly to the external tuberosity c 

 the femur, and interiorly to the outer margin of the head of tb 

 fibula about \ inch anterior to the styloid process. The ligam€
