So far the analyses of the polarized structure functions of the proton and neutron have been limited to the evaluation of their integrals and comparing them to the prediction of the static quark model of the nucleon. We extended our analysis to the x dependence of the polarized structure functions and observe: the measured structure function excellently agrees with the prediction of the static quark model for Bjorken x>0.2 and drops rapidly for x<0.2. It is suggested that for Bjorken x>0.2 electrons get scattered on the undamaged constituent quarks (alias valence quarks) denoted as quasi-elastic scattering on the constituent quarks and for x<0.2 the constituent quarks fragment. In the fragmentation strong interaction is involved which does not preserve the polarization.
