In 1936, Michel Salmon recorded the anterior one-third of the minor labia to be perfused by a branch deriving from the external pudendal artery and the posterior two-thirds by small internal pudendal branches that run perpendicular to the labial long axis. The two systems anastomose to form an arcade along the labial free rim. Note that central arteries may bilaterally be observed running to the most protruding part of the labial free rim.
