The mouse tongue, like that of the cat and many other species, feels like sandpaper due to the numerous tall, pointed filiform papillae.
Stratified Squamous Epithelium - difficult to examine on the anterior surface because of the many filiform papillae, but is easily observed on the underside of the tongue.
Filiform papillae - parallel lines of lightly keratinized, pointed projections that cover most of the anterior surface of the tongue.
These papillae are mechanical and provide friction for holding of food during mastication.
Do not contain taste buds.
Skeletal Muscle - arranged in three bundles at right angles to each other to allow flexibility and precision in movements of the tongue.
