|Labia majora and pudendal cleft|
|Latin||labium majus pudendi|
|Gray's||subject #270 1265|
|Artery||Deep external pudendal artery|
|Nerve||Perineal branches of posterior femoral cutaneous nerve|
The labia majora constitute 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.
The labia majora are thicker in front, where they form by their meeting the 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 to, each other.
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 labia minora are the interlabial sulci.
