  The special relativistic dynamical equation of the Lorentz force type can be
regarded as a consequence of a succession of space-time dependent infinitesimal
Lorentz transformations as shown by one of us \cite{buitrago} and discussed in
the introduction below. Such an insight indicates that the Lorentz-force-like
equation has an extremely fundamental meaning in physics. In this paper we
therefore present a set of dynamical Weyl spinor equations {\em inducing} the
extended Lorentz-force-like equation in the Minowski space-time. The term
extended refers to the dynamics of some additional degrees of freedom that may
be associated with the classical spin namely with the dynamics of three
space-like mutually orthogonal four-vectors, all of them orthogonal to the
linear four-momentum of the object under consideration.
