* 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.
* 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.
* The main bulk of the cervix is composed of tough, collagenous tissue with relatively little smooth muscle.
* Under the squamocolumnar junction, the cervical stroma is infiltrated with leukocytes which defend against microorganisms.
* It is the cervical stroma that is influence by the ovarian hormones.
