  The strong coupling form factors related to the strong vertices of the
positive and negative parity nucleons with the heavy
$\Lambda_{b[c]}[\Sigma_{b[c]}]$ baryons and heavy $B^*[D^*]$ vector mesons are
calculated using a three-point correlation function. Using the values of the
form factors at $Q^2=-m^2_{meson}$ we compute the strong coupling constants
among the participating particles.
