cervix

[sur′viks] pl. cervices [sur′visēz] cervixes

Etymology: L, neck

, the part of the uterus that protrudes into the cavity of the vagina. The cervix is divided into the supravaginal portion and the vaginal portion. The supravaginal portion is separated ventrally from the bladder by the parametrium, which attaches to the sides of the cervix and contains the uterine arteries. The vaginal portion of the cervix projects into the cavity of the vagina and contains the cervical canal and the internal and external os of the canal. The mucous membrane lining the endocervix is broken by numerous oblique ridges, deep glandular follicles, little cysts, and papillae. Also called neck of uterus. See also effacement.

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.
