Lateral Tarsal and Arcuate Arteries (O.T. Tarsal and 

 Metatarsal). The tarsal artery arises opposite the navicular 

 bone, and the arcuate artery near the bases of the metatarsal 

 bones. They both run laterally under cover of the extensor

 There they anastomose with branches of the lateral plantar 

 artery. The tarsal artery also anastomoses with the lateral 

 malleolar and peroneal arteries. 



From the arch which is formed by the arcuate artery 

 three dorsal metatarsal arteries proceed, one to each of the 

 three lateral interosseous spaces. At the clefts between the 

 toes these divide and supply dorsal digital twigs to the
