Directions for Dissecting the Cutaneous Vessels and Nerves. Consult figures 

 105 and 1 06. Plow through the upper fat-bearing strata of the superficial fascia 

 with the forceps never with the scalpel. You will find all the vessels and 

 nerves in the deep layer of the superficial fascia. Divide the fascia in the direction 

 of the vessels and nerves. 



The radial veins converge to form the cephalic vein above the elbow.
