(4 of 30) Cross-Section Through the Tongue In this cross-section through the tongue note the absence of a submucosa. Skeletal muscle fibers anchor directly into the lamina propria (A). The overlying epithelium (B) is of the non-keratinizing stratified squamous type. The bundles of skeletal muscle fibers (C) run in 3 planes: transverse, longitudinal and vertical. The tongue is the only organ where skeletal muscle fibers intersect at right angles.	Legend A - lamina propria B - non-keratinized stratified squamous epithelium C - skeletal muscle
