The dynamics of the musculo-skeletal system are determined by the complex interactions of articulated rigid bodies in
the skeleton and elastic muscles. Here, a computer simulation is done to predict the dynamics of the many contacts
and collisions coupled with elastic tissues in the upper limb during a simple motion of the arm.
The digital anatomy must be represented by discrete, lego-like, geometric primitives on the computer. The primitive
of choice below is a tetrahedron. These simple building blocks must be assembled to represent each individual
anatomic structure. Here we see various muscles in the upper-limb and head.
