Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How far is the cervix from the vaginal opening?Doctor's answer:
The vagina is a slightly flattened, muscular tube with great elasticity, located centrally at the outlet of the small pelvis. It is a slightly flattened, muscular tube connecting the internal and external genitalia. Normally, the anterior and posterior walls are in contact, forming a fissure-like structure. The upper end is wider and connects to the cervical canal of the uterus, opening downwards into the vaginal vestibule. The upper part is relatively broad and attaches to the vaginal portion of the cervix, encircling the cervix and forming a ring-like groove, which is referred to as the anterior, posterior, left, and right fornices. Among these, the posterior fornix is the deepest, making the posterior wall of the vagina (10–12 cm) longer than the anterior wall (7–9 cm). The anterior wall is adjacent to the bladder and urethra, the upper part of the posterior wall is adjacent to the deep of the rectum and uterus, the middle part is closely attached to the rectum, and the lower part is separated from the anus by the perineal body, which is composed of connective tissue.
