 anterior surface of 

 the leg, then between 

 the two heads of the 

 3f. t ilia fi* anticiiz to 

 the dorsum of the 

 foot, where it is con- 

 tinued as the Artr- 

 ria dor salts pedi*. It 

 supplies : 



a. Rami mv.scv.la.re* 

 to the 31. peronriix. 

 3f. extensor cr 

 and to the 31. flexor 

 tarsi ante 'or. 



b. The Art. cuta- 

 nea cntri. Infeni-r 

 (c.c.i.} passes between 

 the two heads of the 

 3f. tili alt* antic us to
