Anatomy of the external genitalia and vagina

The external genitalia (vulva) refers to parts that are accessible to inspection. The composition of the external genitalia includes: pubis, large and small labia, vestibule, clitoris, hymen, large vestibular (Bartolinium) glands, paraurethral throat (skinhead glands) and perineum.


Pubis

Lobok-the lower part of the anterior abdominal wall, which is prominent in the form of a "cushion" due to the accumulation of subcutaneous adipose tissue; HAIR appears in 10 (7-11) years.

Large labia

Large lips - two skin folds going from the pubis from front to back, where they diverge, form a transverse fold - the back solder. The outer surface of the labia majora with the onset of puberty (as well as the stubble) is covered with the hair covering. The upper border of the hairline is a horizontal line. The skin of the inner surface of large lips is tender, similar to the mucous membrane. There are sebaceous and sweaty glands. The space between the large labia is called the sex slit.

Small labia

Small lips - skin folds, located inside the large labia, covered with a delicate skin, similar to the mucous membrane, do not contain fatty tissue. Behind the small labia, gradually flattening, merge with the large genital lips of their lower third. Small labia and clitoris contain an abundance of sebaceous glands.

Clitoris

Clitoris-unpaired organ, analogous to the penis, is located in the upper corner of the sexual gap between the branches of the small labia. In the thick of the labia majora, in the lower third of them, from each side there is one large gland of the vestibule (Bartholinium). They perform a secretory function, moisturizing the entrance to the vagina.

The vestibule of the vagina

The vestibule becomes prominent when the labia is diluted. This space is bordered from the front by the clitoris, with the sides of the inner surface of the large and small gum lips, behind the posterior adhesion and between the shoulder and the shoulder, a navicular fossa. The vestibule of the vagina is lined with a mucous membrane containing glands and multiple crises (indentations). This epithelial cover, as well as the vulva as a whole, is rich in nerve endings, blood and lymphatic vessels. In the center of the door is the entrance to the vagina, surrounded by a hymen.

Hymen

Virginflesh - the connecting membrane, the outer and inner surfaces of which are covered with multilayer flat epithelium. In the thickness of the spit are bundles of izelasticheskih fibers. The shape of the hymen is diverse.

In the vestibule, the vagina opens: the ducts of the large vestibular (Bartholinium) glands and the paraurethral throat, the external opening of the urethra (urethra), which is located below the clitoris. The urethra is 3 cm long. In adult women, it represents an almost straight canal. In the wall of the urethra are the skinheads (paraurethral passages) running parallel to the urethra and opening near the opening. Visually visible visually, their exit holes can sometimes be taken outside the urethra. The clinical significance of these glands is that they can be the place of resting gonococci. In early childhood, glands are weakly expressed.

Vagina

The vagina belongs to the inner genitalia, it is a muscular-elastic tube located between the urethra and the bladder in front and the rectum behind. The length of the female is about 10-12 cm. The vagina is lined with a mucous membrane covered with multilayered flat epithelium. The vagina is devoid of glands, but in the lumen of it there is always a secret. The vagina performs several important functions, one of which is drainage.

Crotch

The perineum, from a gynecological point of view, is called the wedge-shaped tissue array located between the rectum and the vagina. Visible from the outside, the crotch base of the perineum is bordered from the front to the posterior adhesion, from behind - by the anus (anus), from the sides by the region of the ischial tubercles. Vanatomically, the perineum is the area of ​​the body, between the anus and the outflow of the urethra, including both the skin and the foreseeurs.

Internal organs, along with the vagina, include: uterus, uterine (fallopian) tubes and ovaries.

In the shakers, a department is located above the vaginal vaults, a superimpository of the cervix. The cervical canal has two openings: an internal pharynx opening into the uterine cavity, and an external pharynx opening into the vaginal cavity. The nasal canal is lined with a cylindrical epithelium, called the endocervix (glandular apparatus of the cervix).

Through the vagina, the vaginal secret is secreted outward, the secret of internal sex organs is called whites, menstruating teenage girls and women have menstrual blood.
