Labia minora

The labia minora (singular: labium minus) or nymphae are two [longitudinal]] cutaneous folds, that normally vary widely in size from woman to woman. They are situated between the labia majora, and extending from the clitoris obliquely downward, lateralward, and backward on either side of the vulval vestibule, between which and the labia majora they end; in the virgin the posterior ends of the labia minora are usually joined across the middle line by a fold of skin, named the frenulum labiorum pudendi or fourchette.

Anteriorly, each labium minus (nympha) divides into two portions: the upper division passes above the clitoris to meet its fellow of the opposite side, although not necessarily its equal in size, forming a fold which overhangs the glans clitoridis, and is named the preputium clitoridis; the lower division passes beneath the glans clitoridis and becomes united to its under surface, forming, with its fellow of the opposite side, although not necessarily its equal in size, the frenulum clitoridis.

On the opposed surfaces of the labia minora are numerous sebaceous follicles.
