 The second of these proper volar digital.^ supplies the ulnar side of the voiar aspect 

 of the thumb and gives oil' a twig to the matrix of t he t liumli nail. The third supplier

volar digitals, which respectively supply the adjacent sides of the second and third 

 digits. 



The third common volar digital communicates with the ulnar nerve, often gives 

 a branch to the third lumbrical muscle, and divides into two proper volar digitals 

 which supply the adjacent sides of the third and fourth digits. 



As the proper volar digitals pass along the margins of the fingers they give off 

 twigs for the innervation of the skin on the dorsum of the second and third phalanges 

 and the matrix of their nails. Each of the nerves terminates in filaments to the 

 pulp of the finger.
