 The plantar ramus of the 

 saphenous artery is COD 

 tinned, as the undid/ tarsal 

 arii ///. along the medial side 



of the flexor aspect of the 



tarsus, and forms the arevs 

 plantaris along with the 

 dorsalis pedis artery. The 

 medial tarsal artery then 

 continues to the distal part 

 of the metatarsus and di- 

 vides into the second, third. 

 and fourth plantar meta- 

 tarsal arteries (aa. mcta- 

 tarsei plantares II. III. el 

 IV). which join the com- 

 mon plantar digital ait cries.

The continuation of the 

 anterior tibial artery appears 

 deep in the sole between the 

 second and third inter- 

 osseous muscles and under 

 cover of the origin of the 

 m. adductor digiti quinti. 

 Anastomosing with the 

 plantar branch of the 

 saphenous artery it forms 

 the plantar arch (arcus 

 plantaris). from which arise
