Recent experiments performed on inclusive electron scattering from nuclear targets have measured the nucleon electromagnetic structure functions F-1 (x, Q(2)), F-2 (x, Q(2)) and F-L (x, Q(2)) in C-12, Al-27, Fe-56 and Cu-64 nuclei. The measurements have been done in the energy region of 1 GeV2 < W-2 <4 GeV2 and Q(2) region of 0.5 GeV2 < Q(2) <4.5 GeV2. We have calculated nuclear medium effects in these structure functions arising due to the Fermi motion, binding energy, nucleon correlations, mesonic contributions from pion and rho mesons and shadowing effects. The calculations are performed in a local density approximation using a relativistic nucleon spectral function which includes nucleon correlations. The numerical results are compared with the recent experimental data from JLab and also with some earlier experiments.
