External genital organs of female reproductive system, female genital system of female reproductive system, including internal and external genital organs and its related organizations. Refers to female genitalia exposed parts of the reproductive organs, also known as the vulva, means the inside of the two stocks from the pubic symphysis to the perineal area, including the mons pubis, the size of the labia, clitoris, vestibule, urethra, vagina and the hymen, vestibule gland, perineum and so on. 1) mons: the pubic symphysis fat pad in front of the uplift, puberty pubic hair began to grow on the skin, the distribution is the tip-down triangle. 2) of the labia majora: For close to two shares of the inside of a pair of uplift of the skin folds, the labia majora on both sides of unmarried women natural close, cover the vaginal orifice and urethra. The maternal effect of the labia majora to the sides of the separation of delivery. 3) The labia minora: the labia majora are located inside the folds of a pair of thin, surface moist and full of nerve endings, it was extremely sensitive to both sides of the labia minora and the mutual integration of the front is divided into two leaves, surrounding the clitoris , the formation of the anterior lobe of the foreskin, the formation of the posterior lobe of the clitoris frenulum. 4) The clitoris: Located on both sides between the top of the labia minora, and the male penis is similar to the organization, the first is rich in nerve ending


s in the clitoris is extremely sensitive, erectile. 5) The vestibule of the vagina: two-prism area between the labia minora, in this area, in front of the urethra, behind the vaginal opening, this region also vestibular bulb and vestibular gland. Also known as vestibular ball sponge ball, have an erection, and its front and the clitoris is connected with the vestibular gland adjacent to the rear surface for the ball cavernosus coverage. Bartholin's gland, also known as Pakistan, is located in the rear of the labia majora, cavernous muscle was covered balls, such as soya bean, about each one. Sexual arousal yellow-white mucus secreted, from the smooth effect, normal inspection can not touch this gland. Female genital mutilation refers to the genital organs within the genital parts, including the vagina, uterus, fallopian tubes and ovaries. Fallopian tubes and ovaries are often referred to as uterine attachment. True pelvis in the lower part of the vagina vaginal center of the sexual organs and menstrual blood discharge channel and the baby is delivered. Before and after the vagina is a muscular tube a little flat, surrounded by top of the cervix, the part around the cervix around the vaginal vault, said, can be divided into front, back, left and right four parts of the deep posterior fornix, the rectum, the uterus is stuck to the top Au, is the lowest position of the abdominal cavity, after the dome after intercourse semen Department is the main site of accumulation, and called the vaginal pool, is conducive to sperm into the uterine cavity. Vaginal opening in the bottom of the rear vestibule of the vagina, bladder and urethra anterior wall and adjacent wall and the rectum close to that vagina in the bladder, urethra and rectum between. The vagina itself is a self-purification, because the vaginal epithelial cells rich in glycogen, which glycogen in the vagina by the parasitic vaginal lactic acid bacteria produce the decomposition. Lactic acid into the acidic environment of the vagina, which prevents the propagation of many pathogenic bacteria. Uterus uterus in the pelvis Central, was inverted pear-shaped, flat front, back slightly prominent, adult uterus is about 7 ~ 8cm, width 4 ~ 5cm, thickness of 2 ~ 3cm, the uterine cavity capacity of about 5ml. Wide upper uterus, called the uterus, the bulging upper part of the uterus is called the end of the end of both sides of the uterine horn uterus, and fallopian tubes connected. The lower part of the uterus narrow cylindrical, said the cervix. The uterus is a hollow organ, cavity covered with mucous membrane, called the endometrium, from puberty to menopause, the endometrium by ovarian hormones, and produce a periodic change in menstruation. Intercourse, the sperm reach the fallopian tubes to the uterus channel. After conception, the uterus to embryo development, the growth of places. Delivery, uterine contractions, expulsion of the fetus and its appendages. Fallopian tube fallopian tube as a pair of slender, curved pipes, one on each side, located on both sides of the uterus, uterine horn interlinked with the inside of the outer end free, and with the ovary close to the total length of about 8 ~ 14cm. Oviduct to the egg and sperm meet place after fertilization fecundity run by the oviduct to the uterine cavity. Tube according to their shape can be divided into four parts: uterine interstitial or call the Department: to pass into the uterine wall part, narrow and short. isthmus: for the period of interstitial outside the lumen was narrow, about 3 ~ 6cm. ampulla: isthmus and in the outer lumen lenient, about 5 ~ 8cm. infundibulum or umbrella department: the end of the fallopian tubes, opening in the abdominal cavity, funnel-shaped free end, there are many organizations to be like, the "pick up the egg" effect. Oviduct by the female hormone, there are cyclical changes of the organization, but obviously not as good as the endometrium. In addition, during ovulation, tubal fluid rapid increase in glycogen content, thereby providing sufficient energy for sperm. Ovarian a pair of flat oval gonadal organs, its main role is to produce eggs and hormones, so women with normal physiological characteristics and fertility. Before puberty, ovarian surface smooth; the onset of puberty after ovulation, the surface gradually uneven, adult female ovaries about 4cm 3cm 1cm size, weighing about 5 ~ 6g, pale; atrophy postmenopausal ovary is small, hardened. Below the ovary in fallopian tube, ovarian ligament lateral to funnel connected to the pelvic wall, the inside of the pelvis, ovaries and uterus ligaments connected to the inherent. No peritoneal ovarian surface, covered by a germinal epithelium, a layer of fibrous tissue within which the ovarian tunica albuginea. Albuginea ovarian tissue under the cortex and medulla can be divided into two parts. In the outer cortex, in which tens of thousands of primordial follicles and dense connective tissue; medulla in the central part of the ovary, containing loose connective tissue and abundant blood vessels, nerves, lymph vessels, and a small amount of ovarian smooth muscle continuous with the suspensory ligaments fiber, medulla is no follicles, smooth muscle fibers have a role in the movement of the ovary. Women as primary ovarian gonadal organ, and its main function is to ovulation and the secretion of female hormones. Ovulation occurs mostly in the middle two periods, in each menstrual cycle, can have 8 to 10 follicles, but generally only one follicle reaches maturity, while the remaining follicles has degraded, forming atretic follicles. Mature ovarian follicle prominent in the surface of the egg follicle rupture leaving discharged from the ovary.
