The posterior t i b i a 1 nerve, N. tibialis posticus, lies at first 

 to the inner side of the posterior tibial artery, which it soon crosses 

 and then lies to its outer side as far as the ankle. In the interval 

 between the inner malleolus and the heel, it divides into the external 

 and internal plantar nerves. Its muscular branches supply the 

 MM. tibialis posticus, flexor longus diyitorum and flexor longus pollicls. 



a) The internal plantar, N. plantar Is interims, lies between M. ab- 

 ductor pollicls and M. flexor dlgitorum brevls ; it divides into seven plantar 

 digital nerves, Nervi digltales plantares, distributed to both sides of 

 the three inner toes and to the inner side of the fourth toe.
