A) consist of extensive areas of areolar tissue bounded by a basal lamina B) consist of a cellular layer complete with tight junctions between adjacent cells C) cover the entire surface of the body and consist of a keratinized stratified squamous epithelium and an underlying layer of areolar connective tissue that is reinforced by a layer of dense connective tissue D) are comprised of areolar tissue component called lamina propria and often lined by simple epithelia that perform absorptive or secretory functions E) contain "epithelial cells" derived from macrophages and fibroblasts of the adjacent connective tissue
