Colour enhanced scanning electron micrograph. Sample from upper region of vagina.The surface tissue being exfoliated is squamous epithelium.The vagina is a muscular tube lined with a mucous membrane, connecting the cervix of the uterus to the exterior.

In anatomy, squamous epithelium (from Latin squama, “scale”) is an epithelium characterised by its most superficial layer consisting of flat, scale-like cells called squamous cells. Epithelium may be composed of one layer of these cells, in which case it is referred to as simple squamous epithelium, or it may possess multiple layers, referred to then as stratified squamous epithelium. Both types perform differing functions, ranging from nutrient exchange to protection.
