into contact with the extensor digitorum longus. At the upper and lower thirds of its course 

 on the front of the leg the artery has the deep peroneal (anterior tibial) nerve to its lateral side 

 In front the artery is covered by the skin, superficial and deep fascia. In its upper two- 

 thirds it IS deeply placed in the cellular interval between the tibialis anterior on the medial 

 side and the extensor digitorum longus and extensor hallucis longus on its lateral side: and 

 in Its lower third it is crossed m the latero-medial direction by the tendon of the extensor
