Re: endocervical transformation zone component

What is your question?

If it is "what is it" this might help.

The cervix is divided into two major zones/areas: exocervix and endocervix. I think of it kind of like a frosted donut. The exocervix is the part scraped during a pap or looked at and biopsied during a colposcopy. The endocervix is the cervical canal. It can't be seen/observed/biopsied during a pap or colpo. An ECC is needed to sample the cells in the canal.

The outer third of the cervix is made up of squamous cells. These are the cells that are sampled during a pap. The upper 2/3 of the cervix is made up of glandular/columnar cells. These cells cannot be seen during a pap/colpo. Between these two types of cells is an area called the transformation zone. That is where the glandular/columnar cells are always changing into flat squamous cells.

Often, dysplasia is detected at that junction/ transition zone.

I hope that helps.
