Pudenda
In mammals, the vulva (: vulvas or vulvae) comprises mostly external, visible structures of the female genitalia leading into the interior of the female reproductive tract. For humans, it includes the mons pubis, labia majora, labia minora, clitoris, vestibule, urinary meatus, vaginal introitus, hymen, and openings of the vestibular glands ( Bartholin's and Skene's). The folds of the outer and inner labia provide a double layer of protection for the vagina (which leads to the uterus). 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 lymph vessels carry lymph away from the vulva to the inguinal lymph nodes. The nerves that supply the vulva are the pudendal nerve, perineal nerve, ilioinguinal nerve and their branches. Blood and nerve supply to the vulva contribute to the stages of sexual a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pudendal Nerve
The pudendal nerve is the main nerve of the perineum. It is a Mixed nerve, mixed (motor and sensory) nerve and also conveys Sympathetic nervous system, sympathetic Autonomic nervous system, autonomic fibers. It carries sensation from the external genitalia of both sexes and the skin around the Human anus, anus and perineum, as well as the Motor neuron, motor supply to various pelvic muscles, including the external sphincter muscle of male urethra, male or external sphincter muscle of female urethra, female external urethral sphincter and the external anal sphincter. If damaged, most commonly by childbirth, loss of sensation or fecal incontinence may result. The nerve may be temporarily anesthetized, called pudendal anesthesia or pudendal block. The pudendal canal that carries the pudendal nerve is also known by the eponymous term "Alcock's canal", after Benjamin Alcock, an Irish anatomist who documented the canal in 1836. Structure Origin The pudendal nerve is paired, me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Pudendal Artery
The internal pudendal artery is one of the three pudendal arteries. It branches off the internal iliac artery, and provides blood to the external genitalia. Structure The internal pudendal artery is the terminal branch of the anterior trunk of the internal iliac artery. It is smaller in the female than in the male. Path It arises from the anterior division of internal iliac artery. It runs on the lateral pelvic wall. It exits the pelvic cavity through the greater sciatic foramen, inferior to the piriformis muscle, to enter the gluteal region. It then curves around the sacrospinous ligament to enter the perineum through the lesser sciatic foramen. It travels through the pudendal canal with the internal pudendal veins and the pudendal nerve. Branches The internal pudendal artery gives off the following branches: The deep artery of clitoris is a branch of the internal pudendal artery and supplies the clitoral crura. Another branch of the internal pudendal artery is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Pudendal Veins
The internal pudendal veins (internal pudic veins) are a set of veins in the pelvis. They are the venae comitantes of the internal pudendal artery. Internal pudendal veins are enclosed by pudendal canal, with internal pudendal artery and pudendal nerve. They begin in the deep veins of the vulva and of the penis and scrotum, issuing from the bulb of the vestibule and the bulb of the penis, respectively. They accompany the internal pudendal artery, and unite to form a single vessel, which ends in the internal iliac vein The internal iliac vein (hypogastric vein) begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to for .... They receive the veins from the urethral bulb, the perineal and inferior hemorrhoidal veins.

Superficial External Pudendal Artery
The superficial external pudendal artery (superficial external pudic artery) is one of the three pudendal arteries. It arises from the medial side of the femoral artery, close to the superficial epigastric artery and superficial iliac circumflex artery. Course and target After piercing the femoral sheath and fascia cribrosa, it courses medialward, across the spermatic cord (or round ligament in the female), to be distributed to the integument on the lower part of the abdomen, the scrotum in the male, and the labium majus in the female, anastomosing with branches of the internal pudendal artery. It crosses superficial to the inguinal ligament. See also * Deep external pudendal artery * Internal pudendal artery The internal pudendal artery is one of the three pudendal arteries.

Deep External Pudendal Artery
The deep external pudendal artery (deep external pudic artery) is one of the pudendal arteries that is more deeply seated than the superficial external pudendal artery, passes medially across the pectineus and the adductor longus muscles; it is covered by the fascia lata, which it pierces at the medial side of the thigh, and is distributed, in the male, to the integument of the scrotum and perineum, in the female to the labia majora In primates, and specifically in humans, the labia majora (: labium majus), also known as the outer lips or outer labia, are two prominent Anatomical terms of location, longitudinal skin folds that extend downward and backward from the mons pubis ...; its branches anastomose with the scrotal or labial branches of the perineal artery.

Labia Majora
In primates, and specifically in humans, the labia majora (: labium majus), also known as the outer lips or outer labia, are two prominent Anatomical terms of location, longitudinal skin 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 Homology (biology), homologous to the male scrotum. Etymology ''Labia majora'' is the Latin plural for big ("major") lips. 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 the vulva—labia majora and labia minora. Traditionally, to avoid confusion with other lip-like structures of the body, the vulvar labia were termed by anatomists in Latin as ''labia majora (''or ''minora) pudendi.'' Embryology Embryologically, they develop from labioscrotal folds. The labia majora after puberty may become of a darker color than the ...

Clitoris
In amniotes, the clitoris ( or ; : clitorises or clitorides) is a female sex organ. In humans, it is the vulva's most erogenous zone, erogenous area and generally the primary anatomical source of female Human sexuality, sexual pleasure. The clitoris is a complex structure, and its size and sensitivity can vary. The visible portion, the glans, of the clitoris is typically roughly the size and shape of a pea and is estimated to have at least 8,000 Nerve, nerve endings. * * Peters, B; Uloko, M; Isabey, PHow many Nerve Fibers Innervate the Human Clitoris?

Perineal Nerve
The perineal nerve is a nerve of the pelvis. It arises from the pudendal nerve in the pudendal canal. It gives superficial branches to the skin, and a deep branch to muscles. It supplies the skin and muscles of the perineum. Its latency is tested with electrodes. Structure The perineal nerve is a branch of the pudendal nerve. It lies below the internal pudendal artery. It accompanies the perineal artery. It passes through the pudendal canal for around 2 or 3 cm. Whilst still in the canal, it divides into superficial branches and a deep branch. The superficial branches of the perineal nerve become the posterior scrotal nerves in men,Essential Clinical Anatomy. K.L. Moore & A.M. Agur. Lippincott, 2 ed. 2002. Page 263 and the posterior labial nerves in women. The deep branch of the perineal nerve (also known as the "muscular" branch) travels to the muscles of the perineum. Both of these are superficial to the dorsal nerve of the penis or the dorsal nerve of the clitoris. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaginal Introitus
In mammals and other animals, the vagina (: vaginas or vaginae) is the elastic, muscular reproductive organ of the female genital tract. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The vaginal introitus is normally partly covered by a thin layer of mucosal tissue called the hymen. The vagina allows for copulation and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, enabling fertilization. Along with pleasure and bonding, women's sexual behavior with other peop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 racemose glands, compound alveolar glandsManual of Obstetrics. (3rd ed.). Elsevier. pp. 1-16. . located slightly posterior and to the left and right of the Vagina#Vaginal opening and hymen, opening of the vagina. They secrete mucus to Vaginal lubrication, lubricate the vagina. They are homology (biology), 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 fossa of vestibule of vagina, navicular fossa. The ducts are paired and they open on the surface of the vulva. Structure The embryological origin of the Bartholin's glands is derived from the urogenital sinus; therefore, the innervation and blood supply are via the pu ...

Labia Minora
The labia minora (Latin for 'smaller lips', : labium minus), also known as the inner labia, inner lips, or nymphae, are two flaps of skin that are part of the primate vulva, extending outwards from the inner Vagina#Vaginal opening and hymen, vaginal and Urethral meatus, urethral openings to encompass the Vulval vestibule, vestibule. At the glans clitoridis, each labium splits, above forming the clitoral hood, and below the frenulum of the clitoris. At the bottom, the labia meet at the ''labial commissure''. The labia minora vary widely in size, color and shape from individual to individual. The labia minora are situated between the labia majora and together form the labia. The labia minora are Homology (biology), homologous to the penile raphe and ventral penile skin in males. 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 ...
