Vulva
The vulva (plural: vulvas or vulvae; derived from Latin for wrapper or covering) consists of the external female sex organs. The vulva includes the mons pubis (or mons veneris), labia majora, labia minora, clitoris, vestibular bulbs, vulval vestibule, urinary meatus, the vaginal opening, hymen, and Bartholin's and Skene's vestibular glands. The urinary meatus is also included as it opens into the vulval vestibule. Other features of the vulva include the pudendal cleft, sebaceous glands, the urogenital triangle (anterior part of the perineum), and pubic hair. The vulva includes the entrance to the vagina, which leads to the uterus, and provides a double layer of protection for this by the folds of the outer and inner labia. Pelvic floor muscles support the structures of the vulva. Other muscles of the urogenital triangle also give support. Blood supply to the vulva comes from the three pudendal arteries. The internal pudendal veins give drainage. Afferent lymp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vagina
In mammals, the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vestibule to the cervix. The outer vaginal opening is normally partly covered by a thin layer of mucosal tissue called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. Although research on the vagina is especially lacking for different animals, its location, structure and size are documented as varying among species. Female mammals usually have two external openings in the vulva; these are the urethral opening for the urinary tract and the vaginal opening for the genital tract. This is different from male mammals, who usually have a single urethral opening for both urination and reproduction. The vaginal opening is much larger than the nearby urethral openi ...

Labia
The labia are part of the female genitalia; they are the major externally visible portions of the vulva. In humans, there are two pairs of labia: the ''labia majora'' (or the outer labia) are larger and thicker, while the '' labia minora'' are folds of skin between the outer labia. The labia surround and protect the clitoris and the openings of the vagina and the urethra. Etymology ''Labium'' (plural ''labia'') is a Latin-derived term meaning "lip". ''Labium'' and its derivatives (including labial, labrum) are used to describe any lip-like structure, but in the English language, ''labium'' often specifically refers to parts of the vulva. Anatomy The labia majora, also commonly called outer labia or outer lips, are lip-like structures consisting mostly of skin and adipose (fatty) tissue, which extend on either side of the vulva to form the pudendal cleft through the middle. The labia majora often have a plump appearance, and are thicker towards the anterior. The anterior juncti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Labia Minora
The labia minora (Latin for 'smaller lips', singular: ''labium minus'', 'smaller lip'), also known as the inner labia, inner lips, vaginal lips or nymphae are two flaps of skin on either side of the human vaginal opening in the vulva, situated between the labia majora (Latin for 'larger lips'; also called outer labia, or outer lips). The labia minora vary widely in size, color and shape from individual to individual. The labia minora are homologous to the male urethral surface of the penis. Structure and functioning The labia minora extend from the clitoris obliquely downward, laterally, and backward on either side of the vulval vestibule, ending between the bottom of the vulval vestibule and the labia majora. The posterior ends (bottom) of the labia minora are usually joined across the middle line by a flap of skin, named the frenulum of labia minora or fourchette. On the front, each lip forks dividing into two portions surrounding the clitoris. The upper part of each li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulval Vestibule
The vulval vestibule (or vulvar vestibule or vestibule of vagina) is a part of the vulva between the labia minora into which the urinary meatus (urethral opening) and the vaginal opening open. Its edge is marked by Hart's line. It represents the distal end of the urogenital sinus of the embryo.Manual of Obstetrics. (3rd ed.). Elsevier. pp. 1–16. . Structure Structures opening in the vulval vestibule are the urethra, vagina, Bartholin's glands, and Skene's ducts. The external urethral orifice is placed about 25–30 millimetres (1–1.2 in) behind the clitoris and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins. Nearby are the openings of the Skene's ducts. The vaginal orifice is a median slit below and behind the opening of the urethra; its size varies inversely with that of the hymen. To the left and right of the vulval vestibule are the labia minora. Anterior to it are the clitoral hood, fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clitoris
The clitoris ( or ) is a female sex organ present in mammals, ostriches and a limited number of other animals. In humans, the visible portion – the glans – is at the front junction of the labia minora (inner lips), above the opening of the urethra. Unlike the penis, the male homologue (equivalent) to the clitoris, it usually does not contain the distal portion (or opening) of the urethra and is therefore not used for urination. In most species, the clitoris lacks any reproductive function. While few animals urinate through the clitoris or use it reproductively, the spotted hyena, which has an especially large clitoris, urinates, mates, and gives birth via the organ. Some other mammals, such as lemurs and spider monkeys, also have a large clitoris. The clitoris is the human female's most sensitive erogenous zone and generally the primary anatomical source of human female sexual pleasure. In humans and other mammals, it develops from an outgrowth in the em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labia Majora
The labia majora (singular: ''labium majus'') are two prominent longitudinal cutaneous folds that extend downward and backward from the mons pubis to the perineum. Together with the labia minora they form the labia of the vulva. The labia majora are homologous to the male scrotum. Etymology ''Labia majora'' is the Latin plural for big ("major") lips; the singular is ''labium majus.'' The Latin term ''labium/labia'' is used in anatomy for a number of usually paired parallel structures, but in English it is mostly applied to two pairs of parts of female external genitals (vulva)—labia majora and labia minora. Labia majora are commonly known as the outer lips, while labia minora (Latin for ''small lips''), which run alongside between them, are referred to as the inner lips. Traditionally, to avoid confusion with other lip-like structures of the body, the labia of female genitals were termed by anatomists in Latin as ''labia majora (''or ''minora) pudendi.''

Pubic Hair
Pubic hair is terminal body hair that is found in the genital area of adolescent and adult humans. The hair is located on and around the sex organs and sometimes at the top of the inside of the thighs. In the pubic region around the pubis bone, it is known as a ''pubic patch''. Pubic hair is also found on the scrotum in the male and on the vulva in the female. Although fine vellus hair is present in the area in childhood, pubic hair is considered to be the heavier, longer and coarser hair that develops during puberty as an effect of rising levels of androgens in males and estrogens in females. Pubic hair differs from other hair on the body and is a secondary sex characteristic. Many cultures regard pubic hair as erotic, and in most cultures it is associated with the genitals, which both men and women are expected to keep covered at all times. In some cultures, it is the norm for pubic hair to be removed, especially of females; the practice is regarded as part of personal ...

Bartholin's Gland
The Bartholin's glands (named after Caspar Bartholin the Younger; also called Bartholin glands or greater vestibular glands) are two pea sized compound alveolar glandsManual of Obstetrics. (3rd ed.). Elsevier. pp. 1-16. . located slightly posterior and to the left and right of the opening of the vagina. They secrete mucus to lubricate the vagina. They are homologous to bulbourethral glands in males. However, while Bartholin's glands are located in the superficial perineal pouch in females, bulbourethral glands are located in the deep perineal pouch in males. Their duct length is 1.5 to 2.0 cm and they open into navicular fossa. The ducts are paired and they open on the surface of the vulva. History Bartholin's glands were first described in the 17th century by the Danish anatomist Caspar Bartholin the Younger (1655–1738). Some sources mistakenly ascribe their discovery to his grandfather, theologian and anatomist Caspar Bartholin the Elder (1585–1629). Function Ba ...

Mons Pubis
In human anatomy, and in mammals in general, the ''mons pubis'' or pubic mound (also known simply as the mons, and known specifically in females as the ''mons Venus'' or ''mons veneris'') is a rounded mass of fatty tissue found over the pubic symphysis of the pubic bones. Anatomy For females, the ''mons pubis'' forms the anterior portion of the vulva. It divides into the labia majora (literally "larger lips"), on either side of the furrow known as the pudendal cleft, that surrounds the labia minora, clitoris, urethra, vaginal opening, and other structures of the vulval vestibule. Although present in both men and women, the ''mons pubis'' tends to be larger in women. Its fatty tissue is sensitive to estrogen, causing a distinct mound to form with the onset of female puberty. This pushes the forward portion of the labia majora out and away from the pubic bone. The mound also becomes covered with pubic hair. It often becomes less prominent with the decrease in bodily estrogen e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sex Organ
A sex organ (or reproductive organ) is any part of an animal or plant that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. In animals, the testis in the male, and the ovary in the female, are called the ''primary sex organs''. All others are called ''secondary sex organs'', divided between the external sex organs—the genitals or external genitalia, visible at birth in both sexes—and the internal sex organs. Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs.
