The labia majora (singular: labium majus) are two prominent longitudinal cutaneous folds 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.

The deep external pudendal artery ( deep external pudic artery) more deeply seated than the Superficial external pudendal artery, passes medialward across the A nerve is an enclosed cable-like bundle of peripheral Axons (the long slender projections of Neurons. The perineal branches of the posterior femoral cutaneous nerve are distributed to the skin at the upper and medial side of the Thigh. Embryology (from Greek grc ἔμβρυον embryon, "unborn embryo" and grc -λογία -logia) is the study of the development The labioscrotal folds (or labioscrotal swellings, or genital swellings) are paired structures in the human Embryo that represent the final stage of development Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The skin is the outer covering of living tissue of an animal (or plant In Human anatomy or in mammals in general the mons pubis (Latin for " pubic mound " also known as the mons veneris (Latin mound of In Human anatomy, the perineum is generally defined as the surface region in both males and females between the Pubic symphysis and the Coccyx. The cleft of venus ( pudendal cleft, pudendal fissure) is the furrow at the base of the Mons veneris where it divides to form the Labia majora The labia minora (singular labium minus) or nymphae are two longitudinal Cutaneous folds on the human Vulva. The interlabial sulci are the grooves between the Labia majora and the Labia minora. In Female Human Anatomy, the clitoral hood, (also called preputium clitoridis and clitoral prepuce) is a fold of Skin The clitoral glans (glans clitoridis is an external portion of the Clitoris. The Frenulum clitoridis (also known as the Crus glandis clitoridis) is a Frenulum on the under-surface of the Clitoral glans, created by the two medial The Hart's Line is the edge of the Vulval vestibule. To its left and right are the Labia minora. The Vulval vestibule (or "Vulvar vestibule" is a part of the Vulva between the Labia minora that the urethral opening and the vaginal opening In Anatomy, the urethra (from Greek ουρήθρα - ourethra) is a tube which connects the Urinary bladder to the outside of The vagina (from Latin, literally " Sheath " or " Scabbard " is a fibromuscular tubular tract leading from the Uterus
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 sebaceous glands are Glands found in the Skin of Mammals Locations and morphology A branched type of Acinar gland, these
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. Areolar tissue (a type of "loose connective tissue" exhibits loosely organized fibers abundant blood vessels and a lot of seemingly empty space Fats consist of a wide group of compounds that are generally soluble in organic solvents and largely insoluble in water The dartos is a layer of smooth muscular fiber outside the External spermatic fascia but below the Skin. In some Male Mammals the scrotum - also 'scrutum' or 'scrootum' - is a protuberance of Skin and Muscle containing the Testicles A nerve is an enclosed cable-like bundle of peripheral Axons (the long slender projections of Neurons. A gland is an organ in an animal's body that synthesizes a substance for release such as Hormones or Breast milk, often into the Bloodstream
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 with, each other.
Together with the connecting skin between them, they form the posterior commisure of the labia majora or posterior boundary of the pudendum. The vulva (from Latin, vulva, plural vulvae or vulvas; see etymology) is the region of the external genital organs
The interval between the posterior commissure of the labia majora and the anus, from 2. The anus is an opening at the opposite end of an Animal 's Digestive tract from the Mouth. 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 thighs are the Labiocrural Folds.
Between the labia majora and labia minora are the interlabial sulci. The interlabial sulci are the grooves between the Labia majora and the Labia minora.
