The '''labia majora''' (singular: ''labium majus'') are two prominent [[longitudinal]] [[cutaneous fold]]s which extend downward and backward from the [[mons pubis]] to the [[perineum]] and form the lateral boundaries of the [[cleft of venus]], which contains the [[labia minora]], [[interlabial sulci]], [[clitoral hood]], [[clitoral glans]], [[frenulum clitoridis]], the [[Hart's Line]], and the [[vulval vestibule]], which contains the external openings of the [[urethra]] and the [[vagina]].
Each labium majus has two surfaces, an outer, pigmented and covered with strong, crisp hairs; and an inner, smooth and beset with large [[sebaceous]] follicles.
Between the two there is a considerable quantity of [[areolar]] tissue, [[fat]], and a tissue resembling the [[dartos tunic]] of the [[scrotum]], besides vessels, [[nerves]], and [[glands]].
The Labia Majora are thicker in front, where they form by their meeting the [[anterior labial commissure|anterior commisure of the labia majora]].
Posteriorly they are not really joined, but appear to become lost in the neighboring integument, ending close to, and nearly parallel with— each other.
Together with the connecting skin between them, they form the [[posterior labial commissure|posterior commisure of the labia majora]] or posterior boundary of the [[pudendum]].
The interval between the posterior commissure of the labia majora and the [[anus]], from 2.5 to 3 cm. in length, constitutes the perineum.
The labia majora correspond to the scrotum in the male.
Between the labia majora and the [[inner thigh]]s are the [[labiocrural fold]]s.
Between the labia majora and labia minora are the [[interlabial sulci]].
