===Commissures===
[[File:Labia commissures.jpg|thumb|200px|right|A) anterior commissure, B) [[Frenulum of labia minora|fourchette]], C) posterior commissure]]

The labia majora are thicker in front, and form the '''anterior labial commissure''' where they meet below the [[mons pubis]]. Posteriorly, they are not really joined, but appear to become lost in the neighboring integument, ending close to, and nearly parallel to, each other. Together with the connecting skin between them, they form another [[commissure]], the '''posterior labial commissure''', which is also the posterior boundary of the vulva. The interval between the posterior commissure and the [[Human anus|anus]], from 2.5 to 3&nbsp;cm in length, constitutes the [[perineum]].<ref>{{Gray's|page=1265|inline=1}}</ref> The anterior region of the perineum is known as the [[urogenital triangle]], which separates it from the anal region. Between the labia majora and the inner [[thigh]]s are the '''labiocrural folds'''. Between the labia majora and labia minora are the interlabial sulci. Labia majora [[atrophy]] after [[menopause]].
