Fig. 11. Estimates of the kinematics of the I7 muscle during biting using the
three-dimensional kinematic model. A schematic view of the I7 muscle during a
biting cycle is shown in Fig.
2B. Averaged lengths are normalized to the cycle times; black
lines are for biting, gray lines are for swallowing. Values are means (solid
lines) ± 1 s.d. (broken lines).
