Fig 5. Contraction forces of the mandible closer muscle over the functional range of the mandibles in degrees (lower abscissa) and the mean fibre length of the closer muscle in mm (upper abscissa).

A)F _m,act i.e. forces generated by faster muscle fibres. The values for left (red) and right mandibles are highly concordant B)F _m,tot. i.e. total muscular forces. Mean passive forces (see Figs 4b and 5) were subtracted from the residual forces prior to the calculation of F _m,tot. Mean muscle fibre lengths and length changes were described in [14].
