Abstract: In this paper, the spin-dependent structure functions of nucleon g₁, and photoabsorption cross sections <sigma>_1/2, <sigma>_3/2 and <sigma>_T in the resonance region are estimated based on the constituent quark model and the properties of the five phenomenological Breit-Wigner resonances P₃₃(1232), S₁₁(1535), D₁₃(1520), P₁₁(1440), and F₁₅(1680). Our results are compared to the recent E143 data of the polarized structure functions g₁(W², Q²) at points Q²=0.5 GeV² and Q²=1.2 GeV² and the data of the total inclusive photoabsorption cross sections.
