a. The first principal component of variance for all subjects swallow task accounts for 58.8% of the shape change variance

b. Plotted morphologies of all subjects swallow task. A scatter plot of summed shape change coded by maximum (pharyngeal 1) or minimum (oral 1) position of hyolaryngeal complex of the between subject analysis shows that principal component 1 is principally defined by hyolaryngeal excursion.

c. Eigenvectors of all subjects swallow task confirms two muscular slings underlie hyolaryngeal elevation
