A stack of flat cells
The cervix is the narrow bottom part of the uterus, or womb. Its outer part faces the birth canal.
The outer cervix is covered by many layers of cells, stacked up like a pile of pancakes. Squamous means flat. The cells at the bottom are rounder, and they get flatter as they move up to the top.
