Vaginal vestibule, belonging to the female external genital organs in a region, is located in the female vulva on both sides of the labia minora between the cleft. The tip is the clitoris, the posterior is the labial tie, and the sides are the inner sides of the labia minora, which are covered with mucous membrane and are more similar in shape to a diamond. There are four important components in this area, including the vestibular bulb, or bulbocavernosus, which is located on both sides of the vestibule and has an erectile function; the vestibular glands, or bartholin glands, which are located on the posterior portion of the labia majora and are covered by the bulbocavernosus muscle, are soybean-sized, one on each side and are capable of secreting mucus; and the opening of the urethra, which is located just behind and under the head of the clitoris, and is susceptible to bacterial lurking. Vaginal opening, located behind the urethral opening of the vestibule is covered with a thin layer of mucous membrane around the edge of the wall, known as the hymen. If you have any other questions, it is recommended that you consult a medical professional for guidance.
