  Starting from a covariant relativistic formalism which uses nucleon and pion
propagators in a nuclear medium, we revise the traditional effects of Fermi
motion, binding and mesonic corrections to the EMC effect. The calculations are
done in a very accurate way, using precise nucleon spectral functions and meson
self-energies and a good reproduction of the EMC data is obtained outside the
shadowing region which is not explored.
