The mucosa lining the cervical canal is known as the endocervix, [5] and the mucosa covering the ectocervix is known as the exocervix. [6] The cervix has an inner mucosal layer, a thick layer of smooth muscle , and posteriorly the supravaginal portion has a serosal covering consisting of connective tissue and overlying peritoneum .
The cervical canal is generally lined by "endocervical mucosa" which consists of a single layer of mucinous columnar epithelium. However, after menopause, the functional squamocolumnar junction moves into the cervical canal, and hence the distal part of the cervical canal may be lined by stratified squamous epithelium (conforming to a "type 3 transformation zone").
Triple smear, also known as vaginal-cervical-endocervical (VCE) smear is a cytopathology technique for identifying lesions of the female genital tract. The smear is prepared on separate areas of a single slide with three distinct samples, each from ectocervix, vagina and endocervix. [1]
The squamocolumnar junction, where the columnar secretory epithelium of the endocervical canal meets the stratified squamous covering of the ectocervix, is located at the external os before puberty. As estrogen levels rise during puberty, the cervical os opens, exposing the endocervical columnar epithelium onto the ectocervix. This area of ...
Colposcopy is not generally performed for people with pap test results showing low-grade squamous intraepithelial lesion (LSIL) or less. SILs are an abnormal growth of epithelial cells, known as a lesion, on the surface of the cervix. Unless the person has a visible lesion, colposcopy for this population does not detect a recurrence of cancer.
In regard to the cervix, squamous metaplasia can sometimes be found in the endocervix, as it is composed of simple columnar epithelium, whereas the ectocervix is composed of stratified squamous non-keratinized epithelium. [2]
The test remains an effective, widely used method for early detection of precancer and cervical cancer. While the test may also detect infections and abnormalities in the endocervix and endometrium, it is not designed to do so. Guidelines on when to begin Pap smear screening are varied, but usually begin in adulthood. Guidelines on frequency ...
The epithelium of the ectocervix is contiguous with that of the vagina, possessing the same properties and function. [14] The vaginal epithelium is divided into layers of cells, including the basal cells, the parabasal cells, the superficial squamous flat cells, and the intermediate cells.
