224 PRACTICAL ANATOMY. 



PERONEUS LONGUS. 



Origin Head and upper two-thirds of the Outer part 

 of the shaft of fibula. 



Insertion Passes down behind the outer malleolus, 

 lying in the same groove as the peroneus brevis, 

 then through a groove on the inferior surface of the 

 cuboid, and is inserted on the inferior surface of the 

 base of the metatarsal of the great toe. 



Nerve Musculo-cutaneus. 

 PERONEUS BREVIS. 



Origin From lower two-thirds of the anterior surface 

 of the shaft of fibula. 



Insertion Passes behind the outer malleolus, and is 

 inserted into the outer part of the base of the meta- 

 tarsal of the little toe. 



Nerve Musculo-cutaneus. 



The tendons of the peroneus longus and brevis pass 

 behind the external malleolus. 

 GASTROCNEMIUS. 



Origin With the soleus forms the calf of the leg ; 

 arises by two heads from above the outer and inner 

 condyles of the femur. 



Insertion About the lower third, becomes tendinous 

 and receives the insertion of the soleus, forming the 

 tendo Achillis, which is inserted on the posterior 

 surface of the os calcis. 



Nerve Internal popliteal. 

 SOLEUS. 



Origin From posterior surface of head of fibula, 

 posterior surface of upper third of shaft of tibia and 

 its oblique line. 



Insertion On the tendon of the gastrocnemius, form-
