What Is the Vulvar Vestibule?

The vaginal vestibule is the fissure area between the labia minora on both sides of the female vulva called the vaginal vestibule. There is an external urethral opening in the front and a vaginal opening in the rear. In the ditch between the labia minora and the hymen, which is equivalent to the junction of 1/3 and posterior 1/3 of the labia minora, there is an opening of the vestibular large gland on the left and right.

Vaginal vestibule anatomy:

1. Vaginal vestibule:

The vaginal vestibule is the fissure between the labia minora. The front and back are narrow and the middle is wide. The front end is sharper than the clitoris, the back end is more blunt, and the rear boundary is the labial lacing. There is a vaginal opening in the center of the vaginal vestibule, with hymen or hymen marks around the mouth. The outer mouth of the urethra is small, located in front of the vaginal opening, behind the clitoris, and is about 2.5 cm from the head of the clitoris. It is generally a short sagittal fissure with a papillary bulge on the periphery. The posterior and lateral sides of the outer urethra often have small openings for the paraurethral glands. In addition, there is a vestibular large gland drainage duct on the left and right sides of the vaginal opening. Vestibular gland openings are located near the urethral and vaginal openings. There is a small dimple between the back of the vaginal opening and the labial lacing. This litter is more pronounced in non-parturients; it is not obvious in most cases.

2. The vagina:

The vagina is a muscular tube connecting the uterus and external genitalia. Its lower end is narrow and opens at the vaginal vestibule with a vaginal opening; the upper end wraps around the vagina of the cervix and forms a ring-shaped gap around it, called the vaginal vault. The vaginal fornix is divided into anterior, posterior, and lateral fornixes. The anterior fornix and lateral fornix are not very obvious, while the posterior fornix is deep, and the septal vaginal wall is adjacent to the uterine rectal depression. The uterine rectal pit is the lowest point of the peritoneal cavity. If there is fluid in the peritoneal cavity, it is mostly stored here.

The vagina is the coitus of a woman, and it is also the channel through which menstrual blood and the fetus excrete. The vagina is a hollow tube. There are thick vaginal sphincter on the periphery of the vagina, which are mainly composed of coccygeal muscles. These muscles play an important role in maintaining the elasticity, expansion ability and sexual activity of the vaginal canal. The vagina is usually closed, and the front and back walls are always close together, like a latent cavity, extending from the cervix to the vaginal vestibule or external opening of the vagina, only about 7-8 cm. The cervix protrudes into the internal vaginal opening, and the space between the cervix and the vaginal wall is called the anterior fornix and posterior fornix. It is about 11 cm long from the external vagina to the top of the posterior fornix. The vaginal wall epithelium has many wrinkles that stretch out during childbirth or intercourse. The vagina itself does not have secretory glands, but there is a rich vascular network around it. When sexually excited, these small blood vessels are highly filled, so a large amount of liquid penetrates into the vaginal wall through the epithelium, so that the entire vaginal canal is fully lubricated, thereby avoiding sexual friction. Damage to the vaginal wall. The vaginal wall usually also secretes a small amount of mucus to keep the vagina moist; vaginal epithelial cells must be continuously shed and renewed, and the shed cells and mucus are mixed to form leucorrhea, which also has a large number of non-pathogenic bacteria growing, which is a normal physiological phenomenon. These non-pathogenic bacteria play an important role in maintaining the normal acidic environment of the vagina, which is a self-cleaning effect of the vagina. Menopause due to atrophy of the vaginal epithelium and surrounding tissues, vaginal wall folds disappear, lighter color, prone to senile vaginitis.

Vaginal vestibular and vaginal vestibular related diseases:

Vaginal bleeding:

1 Overview:

Vaginal bleeding refers to all those who have vaginal bleeding except for normal menstrual vaginal bleeding. Blood from vaginal bleeding can come from the vulva, vagina, cervix and uterus, fallopian tubes and other parts.

2. The causes of bleeding are:

Ovarian endocrine dysfunction, ectopic pregnancy, genital tumor, genital tract inflammation, injury or foreign body, systemic disease, etc. Age has important reference value for the identification of vaginal bleeding. Malignant tumors should be considered in young girls and postmenopausal vaginal bleeding. Adolescent women should first think of functional uterine bleeding. Women of childbearing age should consider pregnancy-related diseases.

3. Vaginal bleeding can be divided into the following types:

Increased menstrual flow, prolonged menstrual period but normal cycle, this type of bleeding generally consider uterine fibroids, adenomyosis, or ovulatory dysfunctional uterine bleeding. Irregular vaginal bleeding with increased blood volume or prolonged bleeding time, this type is often the performance of anovulatory dysfunctional uterine bleeding, but endometrial cancer should be ruled out. long-term continuous vaginal bleeding without any discernable cycle, this type is generally a malignant tumor of the genital tract, especially the possibility of cervical cancer or endometrial cancer should be considered first. Irregular bleeding after menopause, this type of women of childbearing age should first consider pregnancy-related diseases, such as abortion, ectopic pregnancy, hydatidiform mole, etc .; menopausal women are mostly dysfunctional uterine bleeding or reproductive tract malignant tumors. Vaginal bleeding with leucorrhea, this type should generally consider diseases such as advanced cervical cancer, endometrial cancer with infection or submucosal fibroids with infection. Hemorrhage after sexual intercourse means that blood appears immediately after intercourse. This type should consider early cervical cancer, cervical polyps, and submucosal fibroids. Inter-menstrual bleeding, or ovulation bleeding, refers to bleeding that occurs between two periods, lasting 3 to 4 days, and the amount of blood is very small. Premenstrual or postmenstrual blood staining refers to a small amount of bloody secretions in the vagina a few days before or after menstrual cramps, which are generally caused by ovarian dysfunction, and may also be caused by endometriosis before menstruation . paroxysmal vaginal blood, this type should consider the possibility of primary fallopian tube cancer.
