What are the features of the structure of the external genitalia?
Lobok, also called often venus tubercle, is the lowest part of the female anterior abdominal wall. Due to the well-developed subcutaneous fat layer, this area slightly rises above the pubic articulation and has a pronounced hairline.
Large labia, according to the classification of the location of female genitalia, also apply to the outer. In appearance, it is nothing but folds of the skin, in the thickness of which fiber is concentrated with a pronounced fat layer. They are located on either side of the genital gaps and border on the sides of the vestibule. In the normal state, in the absence of sexual arousal, the labia majora are closed along the median line, thus creating a mechanical defense of the entrance to the vagina and urethra.
Small labia also belong to a type of external female genitalia. These skin folds are rather tender and are located on the inside of the large labia. In its composition contain a large number of sebaceous glands, densely provided with blood vessels and nerve endings. Front converge above the clitoris and form a front soldering, behind - merge with the large labia.
The clitoris is similar in structure to the male sexual organ. Therefore, during sexual intercourse, it also increases in size. It is supplied with a large number of nerve endings, - it is he who concentrates sexual sensations.
The vestibule of the vagina is a space that is confined to the sides by small labia, in front of the clitoris, and behind - by the posterior adhesion of the labia. From above it is covered with a hymen (or its remnants after defloration).
Bartholin glands are located in the thickness of the large labia. When sex separates the lubricant.
What are the characteristics of internal reproductive organs?
Having dealt with what kinds of external female genitalia there are, let us consider the anatomical formations related to the internal.
The vagina refers to organs that are directly involved in sexual intercourse, and when giving birth is part of the birth canal. From the inside, the body is lined with mucosa with a large number of folds, which, stretching, increase the length of the organ.
Uterus is the central reproductive organ in which the conception and development of the fetus occurs. In appearance it has the shape of a pear. The walls of the uterus contain a well developed muscular layer, which allows the organ to grow several times in size when the baby is born.
On the sides of the uterus the uterine (fallopian) tubes depart . After them, after ovulation, the mature egg moves to the uterus. It is in the tube that fertilization usually takes place.
Ovaries are a glandular organ, the main function of which is the synthesis of sex hormones - estrogens and progesterone.
