  We show how Jacobian elliptic functions (JEF) can be used to solve ordinary
differential equations (ODE) describing nonlinear dynamics of microtubules
(MT). We demonstrate that only one of JEFs can be used while the remaining two
do not represent the solutions of the crucial differential equation. We show
that a kink-type soliton moves along MT. Beside this solution, we discuss a few
more that may or may not have physical meaning. Finally, we show what kinds of
ODE can be solved using JEFs.
