  We report on the recent results of the hypercentral Constituent Quark Model
(hCQM). The model contains a spin independent three-quark interaction which is
inspired by Lattice QCD calculations and reproduces the average energy values
of the SU(6) multiplets. The splittings are obtained with a SU(6)-breaking
interaction, which can include also an isospin dependent term. The model has
been used for predictions concerning the electromagnetic transition form
factors giving a good description of the medium $Q^2$-behaviour. In particular
the calculated helicity amplitude $A_{{1/2}}$ for the $S_{11}(1535)$ resonance
agrees very well with the recent CLAS data. Furthermore, we have shown for the
first time that the decreasing of the ratio of the elastic form factors of the
proton is due to relativistic effects. Finally, the elastic nucleon form
factors have been calculated using a relativistic version of the hCQM and a
relativistic quark current.
