Female vagina structure

The area between a woman's legs has always been one of the world's greatest mysteries. Many people are curious about the female vagina. A normal female vagina usually has mons pubis, labia majora, labia, clitoris, vagina, uterus and ovaries. So, what is the structure of a woman's vagina? What are the key features and functions of each of these parts of the female genitals?

1. Mons pubis

The mons pubis (monsveneris) is the private part protruding in front of the ischial tuberosity, composed of skin and a thick layer of fat. Below the mons pubis are the labia majora on both sides. During puberty, pubic hair begins to grow on the mons pubis skin, and its distribution is a triangle with a downward point. The rich adipose tissue under the skin of the mons pubis and the pubic hair on the skin play a supporting and shock-absorbing role during sexual intercourse. Stroking or gently kneading the mons pubis can have a sexually stimulating effect, and rubbing the mons pubis of a man and a woman against each other can make women feel sexually.

2. Labia majora

The labia majora (labium majuspudendi) are a pair of long, ring-shaped, raised skin folds on both sides of the private parts, close to the inner side of the thighs. It is connected to the mons pubis in front and the perineum in the back; it stretches downward and backward from the mons pubis, and the left and right labia majora in front meet at the mons pubis to form the front meeting, and the two ends in the back meet below the frenulum of the labia to form the posterior labial meeting. The posterior meeting is located in front of the anus, but is not as obvious as the anterior meeting. Male pubic hair grows outside the labia majora. The subcutaneous tissue is composed of thick loose adipose tissue, collagen fibers and venous plexus, which are prone to form abscesses after injury. The labia majora contain sebaceous and epidermal glands. The skin on the outer side is pigmented and has male pubic hair on it; the inner side is light pink, close to the mucous membrane, and has no pubic hair on it. The labia majora of adult single women and obese women are of course close together, covering the labia, vulva and urethra. The labia majora of a primipara will separate to the sides due to the impact of childbirth. The labia majora covers the labia, vaginal opening and urethral opening. When there is sexual desire, the labia majora stretch out, exposing the covered area and even revealing the vaginal opening. The labia majora vary greatly from person to person, some are fat and thick, while others are small and thin.

3. Labia

The labia (nympha) is a pair of thin mucous membrane wrinkles on the inner side of the labia majora, with a smooth, hairless and moist surface. The color is brown or pink, bright red, black, white and red. The upper branches of the upper and lower labia majora cooperate with each other and are further divided into two leaves. The skin fold above is called the clitoral hood, and the skin fold below is called the clitoral frenulum. The clitoris is located in the middle of them. The lower part of the labia majora meets at the bottom of the vulva and forms the frenulum. There are rich nerves under the labia mucosa, so it feels sensitive. Very similar to the male urethral labia. Because the labia majora and labia minora are rich in sympathetic nerves, they play an important role in sexual excitement and arousal, and during sexual intercourse, the male penis twitches in the female vagina and touches the labia majora to stimulate the clitoris.

4. Yindi

The clitoris, also known as the clitoris, is located at the top between the two labia and is the meeting point of the upper part of the two labia majora. It is a small cylindrical human organ, surrounded by the clitoral hood, about 4 cm long. The tail end is a round opening with a large tip called the glans clitoris. The surface layer of skin is connected to the inner end by a thin bundle of hardened tissue. The erectile tissue is a kind of corpus cavernosum tissue (composed of two erectile corpora cavernosa, divided into three parts: head, body and foot. Equivalent to the male corpus cavernosum), with rich venous plexus and rich peripheral nerves, so it feels sensitive and bleeds easily after being injured. Although the clitoris is located in the reproductive organ position, it does not have a reproductive function and is only the most important sexually sensitive area. The clitoris, especially the glans clitoris, is covered with nerve endings. Mild touch or stimulation can cause obvious sexual arousal and sexual sensation, and even moderate stimulation can make women achieve sexual pleasure. Therefore, it is also the most stimulating position for women to masturbate. During sexual intercourse, the male genitals generally do not stimulate the clitoris immediately. Instead, the male genitals twitch in the female vagina and touch the labia, which in turn stimulates the clitoris. A woman's clitoris is equivalent to a man's penis, and the glans clitoris is equivalent to the glans of the penis. Except for the smaller corpus cavernosum and the urethra, it is already very complete like the male genitalia, including the clitoral body, crus, glans penis, prepuce, corpus cavernosum and fascia, as well as the pectinate septum and the clitoral suspensory tendon. Accept that you get hard when you're sexually excited.

5. Vestibular Function

The diamond-shaped area surrounded by the labia majora is called the vaginal vestibule. Use your fingers to spread the labia to the left and right, and it will appear. The surface is covered with mucous membrane, which is similar to a triangle. The top of the triangle is the clitoris, the bottom is the frenulum, and the two sides are the labia. The external urethral opening is at the functional upper end of the vestibule. The vagina is below it. There is a Bartholin's gland opening on each side. The vestibular bulbs are also found in this area. The small, diffuse vestibular glands are very similar to the paraurethral glands in men. Further down you can see the yellow chrysanthemum-shaped anus. There is a small space between the vagina and the anus.

6. Vestibular bulbs

It is a pair of penile cavernous tissues, also known as the bulbar penis cavernous body, which has the property of being hard. Located in the shallow layer on both sides of the vestibule of the vulva, it is connected to the clitoral vein in front and the greater Bartholin's gland in the back. A spongy structure consisting of a venous plexus surrounded by the tunica albuginea and shaped like a horseshoe. Because the surface is covered by the bulbospongiosus muscle, when the muscle contracts, it compresses the vestibular bulb and makes the vaginal opening smaller. The vestibular bulb can experience psychological and local stimulation and the chain reaction caused by clitoral stimulation, thus causing swelling. Bleeding easily after being injured.

7. Bartholin's glands

Also known as Bartholin gland. Located at the bottom of the vagina, behind the labia majora on both sides, it is also covered by the bulbospongiosus muscles. It is a round or oval glandular duct as big as a small cowpea on each side. Its gland is very small, about 1.5 to 2 centimeters, opening in the groove at the junction of the inner side of the lower end of the labia and the middle and lower 1/3 of the hymen. The outer skin of the gland is mostly squamous epithelium, and only the inner end of the tube is composed of a layer of columnar cells. During sexual stimulation, reddish-brown mucus is secreted, which plays a role in lubricating the vulva. This gland duct cannot be touched during normal examination. Equivalent to the male bulbourethral gland.

8. Urethra

The external urethral orifice is close to the outer edge of the ischial tuberosity and the middle of the vulva, just below the clitoris. It is an irregular oval-shaped small round hole through which urine is discharged. There is a pair of glandular ducts on the posterior wall, called paraurethral glands, which open on the posterior wall of the urethral opening and are often where pathogens lurk. Because the urethral opening is short and straight, and is located between the clitoris and the vulva, it is often easy to bring bacteria into the urethral opening during sexual intercourse, causing infection. Just below the urethral opening is the vaginal opening.

9. Vulva

The vaginal opening is below the urethral opening. It is the passage inside the vagina. The plastic film at the entrance is the broken hymen.

10. The hymen is broken

The hymen is located at the junction of the vulva and the vestibule of the vagina. It is a thin film of tissue that surrounds the vulva and has a hole in the middle and is not completely closed. There is a hole or porous structure in the middle, which is called the hymenal hole. Most of the holes are ring-shaped, elliptical, crescent-shaped or irregularly cracked. The porous structure is sieve-like. The hymen breaks and menstruation is discharged through the small round hole. Its size, shape, thickness vary from person to person. Most Virgos have a biperforated hymen. The hymen is often torn during the first sexual intercourse, causing pain and bleeding. After the hymen is broken, the mucous membrane appears as many round balls, which become the hymen scar, and only the remnants are left after the pregnant woman gives birth. Some women are born without a hymen, or their hymen is torn during excessive exercise. In ancient times, whether the rupture of the hymen was a sign of virginity or chastity, in fact, the rupture of the hymen cannot indicate anything.

The private parts are the main female sexual organs, the receptors for sexual excitement, and the organs that express female sexual function. The private parts are rich in nerve endings and extremely sensitive to touch, making them a key erogenous zone for women. Caressing the private parts can arouse sexual desire, sexual excitement, and even multiple sexual climaxes. If vaginal dryness occurs during sexual intercourse, you can try using Durex KY lubricant to solve it.

The appearance of the vulva varies from person to person, which is related to the shape of the labia majora, labia majora, hymen, clitoris, etc. This difference in appearance has no significant impact on the endocrine system; but in self-awareness consultation, there are also psychological distress caused by thinking that one's own private parts are different from the patterns in magazines. Artist Betty. When Dortmundsen was 20 years old, he used a mirror to peek at his vulva for the first time and found that his private parts were a bunch of hanging flesh (because his labia were stretched), so he felt disgusted and scared, and thought his body was deformed and ugly (compared with the standard model picture in the anatomical diagram). It was not until she was 35 years old that her husband told her that "your private parts are beautiful" that she changed her mind. Later, she used her pen to draw and help many women build confidence in their private parts.
