Fig. 4. Timing of kinematic, strain and activation events relative to peak gape.
The timing ± S.E.M. (among individuals
not within) relative to peak gape are displayed. (The same information is
given in row three of Table 1.)
The following events were all nearly simultaneous: (1) the onset of slow jaw
opening and of fascicle strain; (2) the onset of fast jaw opening and of fast
fascicle strain; (3) the onset of jaw closing, peak fascicle strain, and the
offset of activity; and (4) the return of the lower jaw and of fascicle to
resting length.
