artery, pierces the soleus and is distributed upon the inner side of 

 the head of the tibia, anastomosing with the inferior internal articular. 

 The Internal calcanean branches, three or four in number, proceed 

 from the posterior tibial artery immediately before its division ; they 

 are distributed to the inner side of the os calcis, to the integument, and 

 to the muscles which arise from its inner tuberosity, and they anasto- 

 mose with the external calcanean branches, and with all the neigh- 

 bouring arteries.

The Internal plantar artery proceeds from the bifurcation of the 

 posterior tibial at the inner malleolus and passes along the inner

 internal plantar. 7. The external plantar artery. 8. The plantar arch giving

 into collateral branches.
