ANATOMY OF THE DOMESTIC POWL 



The ligamentum capsulare capituli fibulce is spread out between 

 the head of the fibula, or capitulum fibulae, and the superficies 

 glenoidalis peronea tibiae.

The ligamentum tibio-fibulare extends from the head of the fibula, 

 or capituluni fibulae, to the inner surface of the external crest, 

 or crista externa tibiae, of the tibia (Fig. 25, No. 3).
