The '''vulva''' is the external part of the female genitalia. It includes the [[mons pubis]], [[labia majora]], [[labia minora]], [[clitoris]], and the openings to the [[urethra]] and [[vagina]]. The vulva plays a crucial role in protecting the internal genital organs and the [[urinary tract]] from infections and injuries.

The '''vulva''' is the external part of the [[female reproductive system]]. It includes the [[mons pubis]], [[labia majora]], [[labia minora]], [[clitoris]], [[vestibule of the vagina]], and the [[urethral opening]]. The vulva serves several functions, including protection of the internal genital organs, sexual arousal, and sensation.

The [[mons pubis]] is a rounded mass of fatty tissue lying over the joint of the [[pubic bones]]. It becomes covered with [[pubic hair]] during puberty.


===Mons Pubis===
=== Labia Majora ===
The [[mons pubis]] is a rounded mound of fatty tissue that covers the [[pubic bone]]. It becomes covered with [[pubic hair]] during puberty. The mons pubis acts as a cushion during sexual intercourse.

The [[labia majora]] are two prominent folds of skin that extend from the mons pubis to the perineum. They contain sebaceous glands and are covered with pubic hair.


===Labia Majora===
=== Labia Minora ===
The [[labia majora]] are two elongated folds of skin that extend from the mons pubis to the perineum. They contain sebaceous glands and sweat glands, and they protect the inner structures of the vulva.
The [[labia minora]] are two smaller folds of skin located between the labia majora. They are highly vascularized and contain numerous sebaceous glands. The labia minora surround the [[vestibule of the vagina]] and form the [[prepuce]] and [[frenulum]] of the clitoris.


===Labia Minora===
=== Clitoris ===
The [[labia minora]] are two smaller folds of skin located within the labia majora. They surround the openings to the vagina and urethra and are rich in blood vessels and nerve endings, making them sensitive to touch.

The [[clitoris]] is a small, sensitive organ located at the anterior junction of the labia minora. It is homologous to the [[penis]] in males and plays a key role in female sexual arousal.


===Clitoris===
=== Vestibule of the Vagina ===

The [[vestibule of the vagina]] is the area between the labia minora that contains the openings to the [[urethra]] and [[vagina]]. It is rich in nerve endings and sensitive to touch.
The [[clitoris]] is a small, sensitive organ located at the top of the labia minora. It is composed of erectile tissue and is homologous to the [[penis]] in males. The clitoris is a key structure in female sexual arousal and pleasure.


===Vestibule===
=== Urethral Opening ===
The vestibule is the area between the labia minora that contains the openings to the urethra and vagina. The [[Bartholin's glands]] are located on either side of the vaginal opening and secrete mucus to lubricate the vagina.
The [[urethral opening]] is located within the vestibule, below the clitoris and above the vaginal opening. It is the external opening of the [[urethra]], through which urine is expelled from the body.


===Perineum===
== Function ==
The [[perineum]] is the area between the vaginal opening and the anus. It is a muscular region that supports the pelvic organs.
The vulva plays a crucial role in protecting the internal genital organs from infection and injury. It also contributes to sexual arousal and sensation, as it contains numerous nerve endings and is involved in the sexual response cycle.


==Function==
== Sexual Arousal ==
The vulva serves several important functions:

* '''Protection''': It protects the internal genital organs and the urinary tract from infections and injuries.
During sexual arousal, the vulva undergoes several changes. The labia minora and clitoris become engorged with blood, increasing in size and sensitivity. This engorgement is part of the body's preparation for potential sexual activity.
* '''Sexual Function''': The vulva is involved in sexual arousal and pleasure. The clitoris, in particular, is a major site of sexual stimulation.
* '''Reproductive Function''': The vulva plays a role in reproduction by facilitating the entry of sperm into the female reproductive tract.

Anatomical structure of the external female genitalia



Anatomy[edit]

File:Genital Diversity Expanded.jpg
Diversity in vulval anatomy

The vulva is the external part of the female reproductive system. It includes the mons pubis, labia majora, labia minora, clitoris, vestibule of the vagina, and the urethral opening. The vulva serves several functions, including protection of the internal genital organs, sexual arousal, and sensation.

Mons Pubis[edit]

The mons pubis is a rounded mass of fatty tissue lying over the joint of the pubic bones. It becomes covered with pubic hair during puberty.

Labia Majora[edit]

Variation in labia minora size and shape

The labia majora are two prominent folds of skin that extend from the mons pubis to the perineum. They contain sebaceous glands and are covered with pubic hair.

Labia Minora[edit]

The labia minora are two smaller folds of skin located between the labia majora. They are highly vascularized and contain numerous sebaceous glands. The labia minora surround the vestibule of the vagina and form the prepuce and frenulum of the clitoris.

Clitoris[edit]

Anatomy of the vulva and clitoris

The clitoris is a small, sensitive organ located at the anterior junction of the labia minora. It is homologous to the penis in males and plays a key role in female sexual arousal.

Vestibule of the Vagina[edit]

The vestibule of the vagina is the area between the labia minora that contains the openings to the urethra and vagina. It is rich in nerve endings and sensitive to touch.

Urethral Opening[edit]

The urethral opening is located within the vestibule, below the clitoris and above the vaginal opening. It is the external opening of the urethra, through which urine is expelled from the body.

Function[edit]

The vulva plays a crucial role in protecting the internal genital organs from infection and injury. It also contributes to sexual arousal and sensation, as it contains numerous nerve endings and is involved in the sexual response cycle.

Sexual Arousal[edit]

Labia becoming engorged with blood during arousal

During sexual arousal, the vulva undergoes several changes. The labia minora and clitoris become engorged with blood, increasing in size and sensitivity. This engorgement is part of the body's preparation for potential sexual activity.

Development[edit]

The development of the vulva begins in the embryonic stage and continues through puberty. The external genitalia develop from the same embryonic structures as the male genitalia, with differentiation occurring due to hormonal influences.
