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").
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 ...
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]
Nabothian cysts are also incidentally found during MRI imaging. During the healing process of chronic cervicitis, squamous epithelium of ectocervix proliferates and enter the cervical canal (endocervix), covering and obstructing the columnar epithelium of endocervical glands. Thus, retention of mucus in the endocervical glands causes cyst ...
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]
Colposcopy (Ancient Greek: κόλπος, romanized: kolpos, lit. 'hollow, womb, vagina' + skopos 'look at') is a medical diagnostic procedure to visually examine the cervix as well as the vagina and vulva using a colposcope.
The cervix is divided into two parts based on the types of cells. The outer portion of the cervix is called the ectocervix, while the inner portion of the cervix is the endocervix. These two portions of the cervix have different types of cells. The area where the endocervix and ectocervix meet is known as the transformation zone.
