Human tongue. Light micrograph of a transverse section through a human tongue. The surface of the tongue (across top) consists of stratified squamous epithelium (dark pink) with a rough keratinised surface. Beneath this are lingual glands (dark purple), which secrete digestive enzymes and mucous. Below this are interlacing bundles of muscles. The oval projections on the surface of the tongue are papillae, which house the taste buds. Magnification: x5 when printed at 10 centimetres wide.
