The outer surfaces of all the organs in the body are lined with a special type of tissue, known as epithelium. The cervix is lined with two different types of epithelium:
- The squamous epithelium, which primarily covers the ectocervix, is composed of multiple layers of squamous cells;
- The columnar epithelium, which forms the lining of the endocervical canal, is composed of a single layer of cells.
The rest of the cervical tissue underlying the epithelium is called the cervical stroma. The stroma contains connective tissue and is rich in blood vessels.
