The properties of ionic waves propagating along a microtubule in solution are analyzed in this paper. We derive the constitutive equations in the continuum limit, obtain appropriate parameter values from the tubulin structural data and solve numerically these equations finding their dependence on the range of parameter values. Possible biophysical implications of the results that may arise from the model are discussed.
