Since the tongue contains no bony supports
for the muscles, the tongue is an example of a muscular hydrostat, similar
in concept to an octopus arm. Instead of bony attachments, the extrinsic
muscles of the tongue anchor the tongue firmly to surrounding bones and
prevent the mythical possibility of 'swallowing' the tongue.
