Antero-posterior, dorso-ventral and medio-lateral dimensions of the odontophore during biting versus swallowing. Antero-posterior, dorso-ventral and medio-lateral dimensions of the odontophore during biting versus swallowing. Measurements were made after the anterior border of I6 had been rotated so that it was vertical. Averaged antero-posterior (A) and dorso-ventral (C) odontophore length normalized to cycle time; black lines are for biting, gray lines are for swallowing. (B,D) Schematic diagrams of lengths measured. (E) Medio-lateral half-widths in biting versus swallowing estimated from the kinematic model. A schematic medio-lateral view of the odontophore is shown in Fig. 2C. The half-width is reported, since this is likely to approximate the medio-lateral extent of the horseshoe-shaped I4 muscle (each half of which underlies the radula). Values in A, C and E are means (solid lines) ± 1 s.d. (broken lines). David M. Neustadter et al. J Exp Biol 2007;210:238-260 © The Company of Biologists Limited 2007
