arises from the posterior ^'s 

 tibial, and divides into seve- fe- 

 ral branches, which are dis- \ 

 tribuled upon the muscles 

 arising from the fibula. 



ANTERIOR TIBIAL. 



This artery perforates 

 the interosseous membrane, 

 at its upper part, and de- 

 scends in front of it to the 

 ankle. Its upper third is 

 situated between the tibialis 

 anticus and extensor lon- 

 gus digitorum muscles; be- 

 low, it runs between the 

 tibialis anticus and extensor 

 proprius pollicis. In its 

 course it gives off nume- 

 rous muscular branches, ^-^^^^lh'7 

 and when it reaches the 

 ankle becomes more super- 

 ficial, being covered by the 

 tendons upon the instep. 



Recurrent tihial^^ as- 

 cends beneath the tibialis 

 anticus, and anastomoses 

 with the arteries of the 

 knee-joint. 



hiternal malleolar.'''^ — Arises from the anterior tibial above the 

 ankle joint, and is distributed upon its inner side. 



External malleolar .'^'^ — Arises below the last, and is distributed 

 upon the outside of the ankle. 



Tarsal.^ — Arises from the anterior tibial, and arches transversely 

 across the tarsus, beneath the extensor brevis digitorum muscle. 



Metatarsal}"^ — Arches across the bases of the metatarsal bones, 

 and gives off three interosseal branches, which supply the toes. 



Dorsal}^ — Is the terminating branch of the anterior tibial, and
