The wall of the vagina fibromuscular tube consists of 3 layers: mucosa, muscularis and adventitia.


===Mucosa===
* stratified squamous epithelium (deep stratum basalis, intermediate stratum spinosum, superficial layers of flat eosinophilic cells
* rests on a very cellular lamina propria (many leukocytes).
* towards the muscularis some vascular cavernous spaces may be seen (erectile tissue).
===Muscularis===
* inner circular and outer longitudinal layers of smooth muscle
* '''bulbospongiosus muscle''' -  (striated) forms an inferior sphincter around the vagina
===Adventitia===
* adventitia bordering the muscularis is fairly dense and contains many elastic fibres.
* outer part of the adventitia loose connective tissue with a prominent venous plexus.

Vagina Histology Overview

(Stain - Haematoxylin Eosin)

The wall of the vagina fibromuscular tube consists of 3 layers: mucosa, muscularis and adventitia.

Mucosa

  • stratified squamous epithelium (deep stratum basalis, intermediate stratum spinosum, superficial layers of flat eosinophilic cells
  • rests on a very cellular lamina propria (many leukocytes).
  • towards the muscularis some vascular cavernous spaces may be seen (erectile tissue).

Muscularis

  • inner circular and outer longitudinal layers of smooth muscle
  • bulbospongiosus muscle - (striated) forms an inferior sphincter around the vagina

Adventitia

  • adventitia bordering the muscularis is fairly dense and contains many elastic fibres.
  • outer part of the adventitia loose connective tissue with a prominent venous plexus.
