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
