Nerve. 



b) The external plantar, N. plantaris externus, lies between 

 MM. flexor brevis digitorum and flexor accessorius, and is divided into a 

 superficial and a deep branch. The superficial separates into 

 three digital branches, which supply the little and outer side of the 

 fourth toes 5 this branch communicates with the internal plantar nerve. 

 The deep or muscular branch accompanies the external plantar 

 artery and supplies all the interossei (except those in the fourth meta- 

 tarsal space), the two outer lumbricales, the Adductor pollids and the 



Transversus pedis muscles.
