 Following are the figures depicting the trajectory of the hyoid in terms of angle and

in terms of displacement (Figures 3-10-3-15). There are great differences in the amount

of movement of the hyoid, with much more extraneous movement of the hyoid observed

in the swallow containing more tongue pumping. The order of the swallow events is the

same in both swallows, but the distribution of the events throughout the length of time is

quite different.
