cer·vi·cal ca·nal

[TA]
a fusiform canal extending from the isthmus of the uterus to the opening of the uterus into the vagina.
Synonym(s): canalis cervicis uteri [TA]

cervical canal

the canal within the uterine cervix, which protrudes into the vagina. The uterine end of the canal is closed at the internal os and, in the nullipara, at the distal end by the external os. The canal is a passageway through which the menstrual flow escapes and, vastly dilated and effaced by labor, through which the infant must pass to be delivered vaginally. Various diagnostic and therapeutic procedures require dilation of the muscular cervix surrounding the canal, including endometrial biopsy, suction and surgical curettage, and radium implantation. Pelvic inflammatory disease is the result of the entry of pathogenic bacteria into the uterus through the cervical canal. Sperm must travel upward through the canal to reach the uterus and fallopian tubes.

cervical canal

Endocervical canal The canal between the uterine cervix and the endometrium, consisting of the endocervix, and lined by endocervical glands; mucus plugs the cervical canal and normally prevents foreign materials from entering the endometrium and uterus

(sĕr'vi-kăl kă-nal') [TA]
