A keratinized stratified squamous epithelium lines the vagina. A thick layer of dense connective tissue, similar to that found in the skin’s dermis, lies beneath the epithelium. It is followed by a layer of loose connective tissue containing numerous blood arteries and nerves. Because they create and stores glycogen, the cells of the vaginal wall usually have a considerable amount of cytoplasm.
