How do the tongue muscles function? My understanding is that muscles only contract. When you extend your arm, it's because of the action of contracting muscles anchored against the bone straightening out your arm. When you bend it, a different set of muscles is contracting to move your arm the other way. So how do the muscles in your tongue act (by contracting) in order for you to extend your tongue? Also, is tongue curling caused by muscle fibers lying "crosswise" on your tongue contracting?
