Abstract
Anatomical studies show that many venous valves are observed in thin cutaneous veins. Because of the variety of the venous valves in both shape and function, and because of the softness of the cutaneous veins, their number and diameters are not crispy. The present study using the fuzzy logic showed that the number of the venous veins in vena basilica and vena cephalica decreased with the increase of their diameters. If we make a fuzzy logical analysis, we can think that these relationships are similar in other cutaneous veins.
