Tongue
The dorsum of the tongue is covered by a stratified squamous keratinized epithelium with filiform, fungiform, and circumvallate (not seen here) papillae. The ventral surface of the tongue is covered by a stratified squamous moist epithelium (lining mucosa). The core of the tongue contains intrinsic and extrinsic skeletal muscles and connective tissue. 10x

Skeletal muscle >
Motility of the tongue is controlled by extrinsic and intrinsic skeletal muscles. The intrinsic muscles, seen here, originate within and insert into the tongue; they change the shape of the tongue. Muscle fibers are arranged in criss-crossing fascicles, seen in longitudinal (arrows) and cross section (X’s).
