Answer 10

The vagina, (from Latin, literally "sheath" or "scabbard" ) is the tubular tract leading from the uterus to the exterior of the body in female placental mammals and marsupials, or to the cloaca in female birds, monotremes, and some reptiles. Female insects and other invertebrates also have a vagina, which is the terminal part of the oviduct. The Latinate plural (rarely used in English) is vaginae.

In common speech, the term "vagina" is often used inaccurately to refer to the vulva or female genitals generally; the vagina is a specific internal structure and the vulva is the exterior genitalia only.

Anatomy

Schematic frontal view of female anatomy.The human vagina is an elastic muscular tube projecting inside a female. It is usually slightly shorter and thinner than an average male penis, at about 4 inches (100 mm) long and 1 inch (25 mm) in diameter (although there is wide anatomical variation) but its elasticity causes it to be able to accept larger penises and give birth to offspring. It connects the vulva at the outside to the cervix of the uterus on the inside. If the woman stands upright, the vaginal tube points in an upward-backward direction and forms an angle of slightly more than 45 degrees with the uterus. The vaginal opening is at the back (caudal) end of the vulva, behind the opening of the urethra. Above the vagina is Mons Veneris. The vagina, along with the inside of the vulva, is reddish pink in color, as with most healthy internal mucous membranes in mammals.

Length, width and shape of the vagina may vary. When a woman gives birth and during sexual intercourse, the vagina temporarily widens and lengthens.[1]

Vaginal lubrication is provided by the Bartholin's glands near the vaginal opening and the cervix and also seeps through the vaginal wall (which does not contain any glands).

The hymen (a membrane situated at the opening of the vagina) partially covers it in many organisms, including many human females, from birth until it is ruptured by sexual intercourse, or by any number of other activities including medical examinations, injury, certain types of exercise, introduction of a foreign object, etc. However, it should be noted that sexual intercourse does not always cause the hymen to be broken, and so (for example) it is not true that a woman with an intact hymen must be a virgin or vice versa.


Functions of the vagina

Labeled picture of external human female reproductive anatomy.From a biological perspective, the vagina performs the following functions:

Providing a path for menstrual fluids to leave the body.
Sexual activity
Giving birth

Menstruation
The vagina provides a path for menstrual fluids to leave the body. In modern societies, tampons, menstrual cups and sanitary towels may be used to absorb or capture these fluids.


Sexual activity
The concentration of the nerve endings that lie particularly close to the entrance of a woman's vagina can provide pleasurable sensation during sexual activity, when stimulated in a way that the particular woman enjoys. This activity may include heterosexual intercourse, during which a male partner's penis is placed within the vagina, manual stimulation (either self, or partner), or other stimulation such as tribadism. An erogenous zone referred to commonly as the G-spot is located at the anterior wall of the vagina, about five centimeters in from the entrance. Some women can experience very intense pleasure if the G-spot is stimulated appropriately during intercourse or other sexual activity. A G-Spot orgasm may be responsible for female ejaculation.


Giving birth
During childbirth, the vagina provides the route to deliver the fetus from the uterus to its independent life outside the body of the mother. During birth, the vagina is often referred to as the birth canal.


Sexual health and hygiene
Main article: vulvovaginal health
The vagina is a self-cleaning organ and needs no special treatment. Doctors discourage Douching, which upsets the balance of vaginal flora and may cause infection and other problems.

The vagina is examined during gynecological exams, often using a speculum, which keeps the vagina open for visual inspection of the cervix or taking of samples (see pap smear).

Vulvovaginal disorders can affect the vagina, including vaginal cancer and yeast infections.


The vagina and popular culture
Western society treats the subject as somewhat taboo. A one-person play by Eve Ensler known as The Vagina Monologues is a rare example of the word appearing in mainstream culture.

The penis (plural penises, penes) is an external male sexual organ. The penis is the male reproductive organ and for mammals additionally serves as the external male organ of urination

Structure

Illustration of the anatomy of the human male genitalia.The human penis is made up of three columns of erectile tissue:

the two corpora cavernosa (singular: corpus cavernosum) and
one corpus spongiosum
The corpus spongiosum lies on the underside (known also as the ventral side) of the penis; the two corpora cavernosa lie next to each other on the upper side (dorsal side).

The end of the corpus spongiosum is enlarged and bulbous-shaped and forms the glans penis. The glans supports the foreskin or prepuce, a loose fold of skin that in adults can retract to expose the glans. The area on the underside of the penis, where the foreskin is attached, is called the frenum (or frenulum).

The urethra, which is the last part of the urinary tract, traverses the corpus spongiosum and its opening, known as the meatus, lies on the tip of the glans penis. It is both a passage for urine and for the ejaculation of semen. Sperm is produced in the testes and stored in the attached epididymis. During ejaculation, sperm are propelled up the vas deferens, two ducts that pass over and behind the bladder. Fluids are added by the seminal vesicles and the vas deferens turns into the ejaculatory ducts which join the urethra inside the prostate gland. The prostate as well as the bulbourethral glands add further secretions, and the semen is expelled through the penis.

The raphe is the visible ridge between the lateral halves of the penis, found on the ventral or underside of the penis, running from the meatus (opening of the urethra) across the scrotum to the perineum (area between scrotum and anus).

The human penis differs from those of some other mammals. It has no baculum, or erectile bone; instead it relies entirely on engorgement with blood to reach its erect state. It cannot be withdrawn into the groin, and is larger than average in the animal kingdom in proportion to body mass.


Linguistics

Etymology
The word "penis" was taken from Latin and originally meant "tail." Some derive that from Indo-European *pesnis, and the Greek word πεος = "penis" from Indo-European *pesos.

The Latin word "phallus" (from Greek φαλλος) is sometimes used to describe the penis, although "phallus" originally was used to describe images, pictoral or carved, of the penis.[1]


Slang
As with nearly any aspect of the human body that is involved in sexual or excretory functions, there are many slang words for the penis. Many of these are noted in the bathroom humor article.

"Penii" is sometimes facetiously or mistakenly used as a plural form of "penis" instead of "penes" or "penises," its correct form.

For slang terms for the "penis," see WikiSaurus:penis — the WikiSaurus list of synonyms and slang words for the penis in many languages.

Puberty
When a boy enters puberty, after the testicles begin to develop, the penis begins to enlarge, alongside the rest of the genitals. The penis grows longer until about the age of 18, but growth in width begins at roughly the age of 13. During the process, pubic hair grows above and around the penis.


Sexual homology
Main article: Sexual homology
In short, this is a known list of sex organs that evolve from the same tissue in a human life.

The glans of the penis is homologous to the clitoral glans; the corpora cavernosa are homologous to the body of the clitoris; the corpus spongiosum is homologous to the vestibular bulbs beneath the labia minora; the scrotum, homologous to the labia minora and labia majora; and the foreskin, homologous to the clitoral hood. The raphe does not exist in females, because there, the two halves are not connected.


Erection
Main article: Erection

A human penis in both flaccid and fully erect states.An erection is the stiffening and rising of the penis, which occurs in the sexually aroused male, though it can also happen in non-sexual situations. The primary physiological mechanism that brings about erection is the autonomic dilation of arteries supplying blood to the penis, which allows more blood to fill the three spongy erectile tissue chambers in the penis, causing it to lengthen and stiffen. The now-engorged erectile tissue presses against and constricts the veins that carry blood away from the penis. More blood enters than leaves the penis until an equilibrium is reached where an equal volume of blood flows into the dilated arteries and out of the constricted veins; a constant erectile size is achieved at this equilibrium.

Erection facilitates sexual intercourse though it is not essential for various other sexual activities. Although many erect penises point upwards (see illustration), it is common and normal for the erect penis to point nearly vertically upwards or nearly vertically downwards or even horizontally straightforward, all depending on the tension of the suspensory ligament that holds it in position. Stiffness or erectile angle can vary.


Size
Main article: Human penis size
As a general rule, an animal's penis is proportional to its body size, but this varies greatly between species — even between closely related species. For example, an adult gorilla's erect penis is about 4 cm (1.5 in) in length; an adult chimpanzee, significantly smaller (in body size) than a gorilla, has a penis size about double that of the gorilla. In comparison, the human penis is larger than that of any other primate, both in proportion to body size and in absolute terms.

While results vary across studies, the consensus is that the average human penis is approximately 12.7-15 cm (5-5.9 in) in length and 12.3 cm (4.85 in) in circumference when fully erect. The average penis size is slightly larger than the median size. Most of these studies were performed on subjects of primarily European descent; worldwide averages may vary.

A research project, summarizing dozens of published studies conducted by physicians of different nationalities, shows that worldwide, erect-penis size averages vary between 9.6 cm (3.7 in) and 16 cm (6.2 in). It has been suggested that this difference is caused not only by genetics, but also by environmental factors such as culture, diet, chemical/pollution exposure[1], etc.

As with any other bodily attribute, the length and girth of the penis can be highly variable between individuals of the same species. In many animals, especially mammals, the size of a flaccid penis is much smaller than its erect size. In humans and some other species, flaccid vs. erect penis size varies greatly between individuals, such that penis size when flaccid is not a reliable predictor of size when erect.

Except for extreme cases at either end of the size spectrum, penis size does not correspond strongly to reproductive ability in almost any species.


Normal variations


Uncircumcised penis (top) compared to a circumcised penis (bottom)Depending on temperature, a flaccid (not erect) penis of average size can withdraw almost completely within the body. During erection the penis will return to its normal (erect) size.

Other variations:
Pearly penile papules are raised bumps of somewhat paler color around the base of the glans and are normal.
Fordyce's spots are small, raised, yellowish-white spots 1-2 mm in diameter that may appear on the penis.
Sebaceous prominences are raised bumps similar to Fordyce's spots on the shaft of the penis, located at the sebaceous glands and are normal.
Phimosis is an inability to retract the foreskin fully, is harmless in infants and pre-pubescent males, occurring in about 8% of boys at age 10. According to the British Medical Association, treatment (steroid cream, manual stretching) does not need to be considered until age 19.
Curvature: few penises are completely straight with curves commonly seen in all directions (up, down, left, right). Sometimes the curve is very prominent but it rarely inhibits sexual intercourse. Curvature as great as 30º is considered normal and medical treatment is rarely considered unless the angle exceeds 45º. Changes to the curvature of a penis may be caused by Peyronie's disease
