| cancer, cervix | Cancer of the entrance to the womb (uterus). Regular pelvic exams and Pap testing can detect precancerous changes in the cervix. Precancerous changes in the cervix may be treated with cryosurgery, cauterization, or laser surgery. The most common symptom of cancer of the cervix is abnormal bleeding. Cancer of the cervix can be diagnosed using a Pap test or other procedures that sample the cervix tissue. Cancer of the cervix requires different treatment than cancer that begins in other parts of the uterus. (12 Dec 1998) |

Cornus dorsalis medullae spinalis, neck of dorsal horn of spinal cord: the constricted portion of the dorsal horn or column, of grey matter in the spinal cord between the base of the horn and the head, also called c. Cornus posterioris medullae spinalis (NA alternative) and neck of posterior horn of spinal cord. C. Dentis, the slightly constricted region of union of the crown and the root or roots of a tooth, also called collum dentis, dental neck and neck of tooth. C. Glandis, collum glandis penis. Incompetent c., one that is abnormally prone to dilate in the second trimester of pregnancy, resulting in premature expulsion of the foetus (middle trimester abortion). C. Mallei, collum mallei. Tapiroid c., a uterine cervix with a peculiarly elongated anterior lip. C. Uteri, neck of uterus: the lower and narrow end of the uterus, between the isthmus and the ostium uteri. (18 Nov 1997) |

| cervix mucus | A slightly alkaline secretion of the endocervical glands. The consistency and amount are dependent on the physiological hormone changes in the menstrual cycle. It contains the glycoprotein mucin, amino acids, sugar, enzymes, and electrolytes, with a water content up to 90%. The mucus is a useful protection against the ascent of bacteria and sperm into the uterus. (12 Dec 1998) |
| cervix of the axon | The constricted portion of the axon just before the myelin sheath begins. (05 Mar 2000) |

| cervix vesicae urinariae | The lowest part of the bladder formed by the junction of the fundus and the inferolateral surfaces. Synonym: cervix vesicae urinariae. (05 Mar 2000) |
| supravaginal portion of cervix | The part of the cervix of the uterus lying above the attachment of the vagina. Synonym: portio supravaginalis. (05 Mar 2000) |
| incompetant cervix | A cervix that is abnormally liable to dilate and so is not competant to keep the foetus up in the uterus and keep it from being spontaneously aborted (miscarried). (12 Dec 1998) |
