What is the cervix?

Uterus Opening: The cervix is the opening of the uterus, or womb, into the vagina. It can be seen during the medical pelvic exam as a circle of muscular tissue with a small opening. Pap smears and some std test swabs are done on the cervix. The word is latin for "neck", referring to the narrowing of the uterus as it enters the vagina.

Opening to womb: It is the lower, narrow portion of the uterus (womb) where it joins with the top end of the vagina. It is the area where cells are obtained during a pap smear to aide in screening for cervical cancer.

Cervix: The cervix (from the latin cervix uteri, meaning "neck of the womb") is the lower, narrow portion of the uterus where it joins with the top end of the vagina. It is cylindrical or conical in shape and protrudes through the upper anterior vaginal wall. Approximately half its length is visible with appropriate medical equipment; the remainder lies above the vagina beyond view. The cervix has an open.
