The '''labia majora''' (singular: ''labium majus'') are two prominent [[Anatomical terms of location|longitudinal]] [[cutaneous fold]]s that extend downward and backward from the [[mons pubis]] to the [[perineum]] and form the lateral boundaries of the [[pudendal cleft]], 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]]. |
