foot (Fig. 128). Here it receives one or two small branches 

 (a and d) from the plantar branch of A. saphena (forming 



with them the plantar arch 

 (f)), and passing distad and 

 slightly laterad, divides into 

 three main portions (r). These 

 (Aa. digitales plantares) pass 

 to the three intervals between 

 the digits. The medial one 

 passes along the lateral side 

 of the second digit; the next 

 divides, sending a branch to 

 the lateral side of the third 

 digit and the medial side of 

 the fourth ; the lateral one 

 passes along the medial border 

 of the fifth digit. The Aa. 

 digitales plantares send num- 

 erous branches to the interos- 

 seous muscles. 



Branches of the tibialis 

 anterior : 



a. A. tibialis recurrens. 

 Immediately after passing 

 through the interosseous mem- 

 brane the anterior tibial sends 

 a small artery proximad to the 

 knee-joint.
