with them the plantar arch 
(c)), and passing distad and 
slightly laterad, divides into 
three main portions (¢). 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.
