Normal cervical epithelium


The cervix is covered by stratified squamous epithelium and columnar epithelium. Normally, the squamous epithelium covers the ectocervix and the columnar epithelium covers the endocervix. The two types of epithelium meet at the squamocolumnar junction (SCJ). The SCJ is usually situated close to the external os of the cervix, although its position changes with the age and hormonal status of the woman.
