Organs of the female reproductive system. From Applegate, 2000.
cervix den´tis neck of tooth.
incompetent cervix a cervix uteri that is abnormally prone to dilate before termination of the normal period of gestation, resulting in premature expulsion of the fetus. Predisposing factors include a previous traumatic delivery and previous dilatation and curettage. It may be corrected during pregnancy by cerclage using a band of fascia or a nonabsorbable ribbon of Mersilene to constrict the cervical os.
cervix u´teri (uterine cervix) the narrow lower end of the uterus between the isthmus and the opening of the uterus into the vagina.
Cervical cancer is surpassed only by lung cancer and breast cancer as a cause of female cancer deaths in the United States. Cervical erosion refers to ulceration of the surface epithelium of the cervix resulting from trauma (as in childbirth) or infection. Cervical lacerations are likely to occur during childbirth. Most small lacerations heal by themselves, but more extensive tears in the cervix may require surgical repair. Cervical polyps are fleshy growths that form on the cervix, causing bleeding, and can be removed surgically.

cervix vesi´cae urina´riae the lower, constricted part of the urinary bladder, near the opening of the urethra.
cervix
pl. cervices; neck; the front portion of the neck (collum), or a constricted part of an organ (e.g. cervix uteri, see below).
double cervix
incomplete fusion of the müllerian ducts leads to duplication of all or parts of the female genital tract. In cows one of these is a duplication of the cervix but with only one uterus. More common is a double external os but a single internal os. Both represent an inconvenience at artificial insemination and are detectable on rectal or vaginal examination.
cervix uteri
the narrow caudal end of the uterus that opens into the vagina.
cervix vesicae
the caudal constricted part of the urinary bladder, proximal to the opening of the urethra.
