a Surface geometry of muscles, bones, subcutaneous tissue, skin and electrodes used for arm modelling (taken from BodyParts3D, The Database Center for Life Science (http://lifesciencedb.jp/bp3d/)). b Cross-section of the volume mesh generated from the arm surfaces. c Uniformly distributed fibres inside a unit circle are grouped into motor units (MUs) of different sizes, locations and territories. d Example of mapping of 10 small motor units from the circle into an arbitrary muscle by morphing the unit circle into the muscle cross section.
