2. Parts of Cervix
Cervical canal
Int. & Ext. os
Vaginal fornix Dr Rajiv Ranjan

3. Cervix
(Endocervicalregion)
Mucosa: (often exhibit deep irregular
folds)
simple columnar epithelium
Invaginates to form highly branched
and tubular cervical glands (oestrogen
dependent)
Glandular Cysts
Lamina propria:vascular, more dense
& fibrous
Muscularis: less compact than
uterusDr Rajiv Ranjan

4. Cervix
(Endocervicalregion)
Endocervicalmucosa has folds and
many large branched cervical glands
Exocervixis similar to vaginal mucosaDr Rajiv Ranjan

5. Cervical
Sq. columnar junction Dr Rajiv Ranjan

6. Vagina
Mucosa(irregular and shows mucosal folds)
LiningStratified squamous epitheliumappears
vacuolateddue glycogenation
lamina p dense irregular connective tissue, rich
in elastic fibres
lymphocyte & neutrophil invasion ++
Ridges & Papillae prominent
No Glands
Muscularis
Inner circular and outer lo
ngitudinal layers of
smooth muscle
Contain vascular cavernous spaces
A
dventitia
Inner part fairly dense and contains many elastic
fi
bres
outer part has loose connective tissue with a
p
rominent venous plexusDr Rajiv Ranjan
