Vagina with its light staining (glycogen accumulation) stratified squamous epithelium which is lightly keratinized (therefore probably from a woman in the follicular phase of her cycle). See the next slide for a higher mag. image demonstrating this. The underlying stroma shows the extensive venous plexus (which dilates during sexual stimulation) which is characteristic of the vagina but not always as evident. The muscularis of the vagina is not in the section.
