Geometry and finite element (FE) model of the muscle tissue. a Geometry of the tissue containing three distinct regions (defined in Table 1) the fascicle, the sounding tissue and the extended tissue. b The fascicle is inside the surrounding tissue and is comprised of 19 muscle fibers each of which is wrapped in an endomysium sheet. c Finite element model of the tissue showing dashed line where the model was cut to obtain axial stress values at this section for analysis
