Squamocolumnar junction

The area around the opening of the cervix where the endocervix (inner part) and ectocervix (outer part) come together. This area contains both glandular cells (cells that make mucus) from the endocervix and squamous cells (thin, skin-like cells) from the ectocervix. Most abnormal cell changes and most cervical cancers begin in the squamous cells of the squamocolumnar junction. Also called transformation zone.
