A dynamical valence and sea quark mixing model is shown to fit the baryonground state properties as well as the spin content of the nucleon. Therelativistic correction and the $q^3{\leftrightarrow} q^3q\bar{q}$ transitionterms induced by the quark axial vector current$\bar{\psi}\vec{\gamma}\gamma^5\psi$ in this model space is responsible for thequark spin reduction.Comment: 11 pages, Latex, one figure, to be published in Phys. Rev. C5
