from the side of the os corome, each is inserted into the upper border of 

 the navicular bone, and sends slips to the wing of the os pedis and 

 inner surface of the lateral cartilage. 



Synovial Membrane. This is supported in front by the extensor 

 tendon, and laterally by the lateral ligaments. A protrusion of it 

 passes on each side between the anterolateral and posterolateral 

 ligaments, and lies in relation to the deep face of the lateral cartilage. 

 A third protrusion passes upwards posteriorly, between the navicular 

 bone and the back of the os corome (Plate 10, Fig. 2).
