Endocervix and ectocervix. Endocervix faces uterus. Ectocervix faces vagina.
The endocervix has which type of epithelium? Ectocervix?
Endocervix - simple columnar
Ectocervix - SSNK
The wall of the cervical canal contains which type of connective tissue?
Dense connective tissue (elastic tissue and collagen)
Where is the squamo-columnar junction?
external os or transformation zone (T zone)
What type of secretion do the glands in the cervical epithelium emit?

The vagina has what type of epithelium?
stratified squamousd non-keratinized (SSNK)
What is the purpose of the glycogen released by the epithelial cells of the vagina?
