Cervix is the lower, narrow portion of the uterus that projects into the vaginal canal.[1] Nulliparous and parous cervixes differ in os shape and cervical dimensions.[2] The cervical epithelium is its surface lining of squamous and columnar epithelium, which meet at the squamocolumnar junction, and this cervical tissue is the surface a screening model has to present.[1] Acetowhite lesions that indicate a positive screen lie close to the squamocolumnar junction, so it is the landmark screening training must find.[2] An acetowhite lesion is a white patch that appears on the cervix after acetic acid is applied, and recognising it is the point of visual-inspection practice.[1]
