The cervix is divided into columnar epithelium and columnar epithelium, and the cervix is divided into columnar epithelium, columnar epithelium and columnar epithelium. The cervix is divided into columnar epithelium and squamous epithelium, the part of the cervix that looks like celiac disease in gynecological examination is columnar epithelium, and the smooth part is squamous epithelium, usually, columnar and squamous epithelium cells are in a dynamic equilibrium, and hormone-related, this area is named “squamous columnar epithelium junction area” in medicine. This area is medically named the “squamous-columnar epithelial junction zone”. Therefore, the so-called cervical erosion, in fact, is the columnar epithelial ectropion, in general, there is no special clinical manifestations, but some people may be because of the “erosion” area is large, and the phenomenon of contact bleeding, but if there is an increase in the leukorrhea, yellow, odor, urinary frequency, urgency, lumbar pain and other symptoms, which is the manifestation of cervicitis. In addition to this, cervical examination can also detect cervical hypertrophy or natriuretic bursa formation. In addition, the squamous column epithelial junction area is also a favorable site for cervical lesions, if once the symptoms, or need to go to the hospital for TCT and HPV examination, to rule out the possibility of cervical lesions.
