Frenulum of clitoris

Anteriorly, each labium minus divides into two portions: the upper division passes above the clitoris to meet its fellow of the opposite side, forming a fold which overhangs the glans clitoridis, and is named the preputium clitoridis; the lower division passes beneath the clitoris and becomes united to its under surface, forming, with its fellow of the opposite side, the frenulum of the clitoris.
