c) The first dorsal interosseous artery 

 arises directly from the Art. dorsalis pedis and 

 divides into three dorsal digital branches, 

 Arteriae digitcdes dorsales, for both sides of the great 

 toe and the inner side of the second toe. The Art. 

 dorsalis pedis then passes between the bases of the 

 I. and II. metatarsal bones into the Planta pedis, 

 and there forms, with the external plantar artery, 

 the plantar arch, Arcus plantar is. 



2. The posterior tibial artery, Art. 

 tibialis postica, descends upon the M. tibialis posticus 

 and M. flexor digitorum longus to the ankle-joint, 

 behind the internal malleolus ; it then passes into 

 the Planta pedis and divides into the external and 

 internal plantar arteries.
