Extensive Definition
The vagina (from Latin, literally
"sheath" or "scabbard") is a fibromuscular
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
to refer to the vulva or
female genitals generally; strictly speaking, the vagina is a
specific internal structure and the vulva is the exterior genitalia
only.
Human anatomy
The human vagina is an elastic muscular canal that extends from the cervix to the vulva. Although there is wide anatomical variation, the length of the unaroused vagina is approximately 6 to 7.5 cm (2.5 to 3 in) across the anterior wall (front), and 9 cm (3.5 in) long across the posterior wall (rear). During sexual arousal the vagina expands in both length and width. Its elasticity allows it to stretch during sexual intercourse and during birth to offspring. The vagina connects the superficial vulva to the cervix of the deep uterus.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 caudal end of the vulva, behind
the opening of the urethra. The upper one-fourth of
the vagina is separated from the rectum by the rectouterine
pouch. 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.
Vaginal
lubrication is provided by the Bartholin's
glands near the vaginal opening and the cervix. The membrane of
the vaginal wall also produces moisture, although it does not
contain any glands. Before and during ovulation, the cervix's mucus glands secretes
different variations of mucus, which provides a favorable
alkaline environment in the vaginal canal to maximize the chance of
survival for sperm.
The hymen is a thin membrane
of connective
tissue which is situated at the opening of the vagina. As with
many female animals, the hymen covers the opening of the vagina
from birth until it is ruptured during activity. The hymen may
rupture during sexual or non-sexual activity. Vaginal penetration
may rupture the hymen. A pelvic
examination, injury, or certain types of exercises, such as
horseback
riding or gymnastics may also rupture
the hymen. Sexual intercourse does not always rupture the hymen.
Therefore, the presence or absence of a hymen does not necessarily
indicate virginity or
prior sexual activity.
Physiological functions of the vagina
The vagina has several biological functions.Uterine secretions
The vagina provides a path for menstrual blood and tissue to leave the body. In industrial societies, tampons, menstrual cups and sanitary napkins may be used to absorb or capture these fluids.Sexual activity
The concentration of the nerve endings that lie 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. During sexual arousal and particularly stimulation of the clitoris, the walls of the vagina self-lubricate, reducing friction during sexual activity. Research has found that portions of the clitoris extend into the vulva and vagina.With arousal, the vagina lengthens rapidly to an
average of about 4 in.(8.5 cm), but can continue to
lengthen in response to pressure. As the woman becomes fully
aroused, the vagina tents (last ²⁄₃ expands in length and width)
while the cervix retracts. The walls of the vagina are composed of
soft elastic folds of mucous membrane skin which stretch or
contract (with support from pelvic muscles) to the size of the
penis. With proper arousal, the vagina may stretch/contract to
accommodate virtually any penis size (or sex toy/object within
reason).
G-spot
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 experience intense pleasure if the G-spot is stimulated
appropriately during sexual activity. A G-Spot orgasm may be responsible for
female
ejaculation, leading some doctors and researchers to believe
that G-spot pleasure comes from the Skene's
glands, a female homologue of the prostate, rather than any
particular spot on the vaginal wall. Some researchers deny the
existence of the G-spot.
Childbirth
During childbirth, the vagina provides the channel to deliver the baby 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. The vagina is remarkably elastic and stretches to many times its normal diameter during vaginal birth.Sexual health and hygiene
The vagina is self-cleansing and therefore usually needs no special treatment. Doctors generally discourage the practice of douching. Since a healthy vagina is colonized by a mutually symbiotic flora of microorganisms that protect its host from disease-causing microbes, any attempt to upset this balance may cause many undesirable outcomes, including but not limited to abnormal discharge and yeast infection. The acidity of a healthy vagina due to lactic acid secreted by symbiotic microorganisms retards the growth of many strains of dangerous microbes.The vagina is examined during gynecological
exams, often using a speculum,
which holds the vagina open for visual inspection of the cervix or
taking of samples (see pap
smear).
Signs of Vaginal Disease
Vaginal Diseases present with lumps, discharge
and sores.
Lumps The presence of unusual lumps in the wall
or base of the vagina is always abnormal. The most common of these
is Bartholin's
cyst. The cyst, which can feel like a pea, is formed by a
blockage in glands which normally supply the opening of the vagina.
This condition is easily treated with minor surgery or silver
nitrate. Other less common causes of small lumps or vesicles are
herpes
simplex. They are usually multiple and very painful with a
clear fluid leaving a crust. They may be associated with
generalized swelling and are very tender. Lumps associated with
cancer of the vaginal wall are very rare and the average age of
onset is seventy years. The most common form is squamous
cell carcinoma, then cancer of the glands or adenocarcinoma and
finally, and even more rarely, melanoma.
Discharge The great majority of vaginal
discharges are normal or physiological and include blood or menses
(from the uterus), the most common, and clear fluid either as a
result of sexual arousal or secretions from the cervix. Other non
infective causes include dermatitis, discharge from
foreign bodies such as retained tampons or foreign bodies inserted
by curious female children into their own vaginas. Non-sexually
transmitted discharges occur from bacterial
vaginosis and thrush or candidiasis. The final group
of discharges include sexually transmitted diseases, gonorrhoea, Chlamydia and
Trichomonas.
The discharge from thrush is slightly pungent and white, that from
Trichomonas more foul and greenish and that from foreign bodies
resembles the discharge of gonorrhoea, greyish or yellow and
purulent( like pus).
Sores All sores involve a break down in the walls
of the fine membrane of the vaginal wall. The most common of these
are abrasions and small ulcers caused by trauma. While these can be
inflicted during rape most are actually caused by excessive rubbing
from clothing or improper insertion of a sanitary tampon. The
typical ulcer or sore caused by syphilis is painless with
raised edges. These are often undetected because they occur mostly
inside the vagina. The sores of herpes which occur with vesicles
are extremely tender and may cause such swelling that passing urine
is difficult. In the developing world a group of parasitic diseases
also cause vaginal ulceration such as Leishmaniasis
but these are rarely encountered in the west. HIV/AIDS can be
contracted through the vagina during intercourse but is not
associated with any local vaginal or vulval disease. All the above
local vulvovaginal diseases are easily treated. Often only shame
prevents patients from presenting for treatment.
