Fascicle in rat SM operate at long relative lengths (A, B) and small strains (C) during incisor-biting. Fascicle relative lengths (L/LO) at activation onset (A) and coincident with peak force (B) increase with food hardness (color scheme as in Fig. 2). Fascicle strains (Ԑ) averaging 5–7% across food types are consistent with the pennate architecture of SM, and with operation beyond the FL plateau5.
