Os

Latin for "mouth". Used to describe the small opening of a woman's cervix, either on the vaginal side of the cervix, or on the uterine side.

Pronounced: "Oz" or "Oss"

"The cervical canal has a constricted opening or os at each end. The internal os communicates with the cavity of the uterus; the external os, with the vagina."
Knowledge is power.
