Numerical modeling for the mechanical properties of human muscles, tendons and intervertebral discs are studied. These parts consist of fibrous tissues and mechanical properties under external load and constriction of muscles are highly anisotropic. In this paper,these parts are modeled as uniform elastic materials with elastic anisotropies and special attention is paid on the,intervertebral discs where fibrous tissues make up a structure like an ellipsoidal basket. Numerical models developed are applied to our musculoskeletal model of a male adult and some simulations are made on the anteflexion and lateral fold of its trunk. Results show that deformation of intervertebral discs with the anisotropic character is more stiff against shear deformation and yet spinal column bend smoothly.
