* The lumen of the cervix is lined by a simple columnar epithelium containing many mucous producing cells. Some cilia may be seen on these cells.
* Uterine cervix protrudes into the upper vagina and contains the endocervical canal that links the uterine cavity with the vagina.
* Uterine cervix protrudes into the upper vagina and contains the endocervical canal that links the uterine cavity with the vagina.
* The endocervical canal is lined by a single layer of tall columnar mucus-secreting cells.
* The endocervical canal is lined by a single layer of tall columnar mucus-secreting cells.
* Where the cervix is exposed to the vagina(the ectocervix), it is lined by thick stratified squamous epithelium.

** Cells of the ectocervix often have clear cytoplasm due to their high glycogen content.

* The junction between the vaginal and endocervical epithelium is abrupt, normally located at the external os. This is the point where the endocervical canal opens into the vagina.
