  The implications of chiral symmetry for the quark model are discussed. In
particular its connection with the meson-baryon approach is outlined. It is
stressed that in the closure approximation, where the intermediate baryon
states are used instead of the original quark basis, it is imperative to take
into account the whole infinite tower of the radially excited states in order
that the crucially important effects related to the short-range part of the
meson-exchange interaction be preserved. It is shown that the chiral
constituent quark model is able to explain the nucleon axial vector coupling
constant and automatically incorporates all the necessary loop corrections.
