Fig. 6. Kinematics of the antero-posterior and dorso-ventral length of the I1/I3/jaw complex during biting versus swallowing. (A,C) Averaged antero-posterior length along the dorsal surface (A) or the ventral surface (C) during biting or swallowing, shown using black or gray lines, respectively. (E,G) Averaged dorso-ventral length at the lateral groove (E) or at the jaw line (G) during biting or swallowing, shown using black or gray lines, respectively. Values are means (solid lines) ± 1 s.d. (broken lines). (B,D,F,H) Schematic diagrams showing the lengths (bold lines) measured to generate these averages for the frames indicated in Fig. 5 through the biting cycle.
