|General Gross Description|
Endocervical canal measures approximately 3.0 cms in length
Endocervical canal lined by deep longitudinal folds and abundant mucus
Internal cervical os is not clear cut as the endometrial-endocervical junction is not sharp
Somewhere near the end of the endocervical canal is the squamocolumnar junction
Squamocolumnar junction is visualized by pink endocervical epithelium meeting grey squamous mucosa
Supplied by uterine arteries; drain to pelvic lymph nodes
|General Microscopic Description|
Endocervix is lined by a single layer of mucin-secreting cells with small often basilar nuclei and mucin filled cytoplasm.
Also may see ciliated cells and subcolumnar reserve cells.
Neuroendocrine cells can be detected with immunohistochemical staining.
Despite the appearance of glands and the use of the term endocervical glands the epithelium is simply deeply clefted.
Exocervix covered by stratified squamous non-keratinizing epithelium. (See Pap smear normals and squamous metaplasia for more details).
