A model of the tongue musculature is introduced which is based on the Equilibrium Point Hypothesis (A model). The model is fitted to mid-sagittal cinera-diographic data in order to extract muscles synergies through a Principal Component Analysis. An assessment of the effects of this commands on tongue shape is done, showing how the degrees of freedom of tongue profile relate to the biomechanical substrate.
