Your
tongue is a very cool thing. It's got plenty of
musclely goodness. The top-most, visible
muscle in your
tongue is the
Superior Longitudinal. The middle part is the
Transverse and Vertical Elements. The bottom part is the
Inferior longitudinal. These all work together to change the shape of your
tongue and aid
eating (
mastication,
talking,
swallowing, and
whatever else a tongue could be used for.
