    "abstract": "We argue that the paradoxal softness of the red blood cells (RBC) in\nfluctuation spectra experiments is apparent. We show that the effective surface\nshear modulus $\\mu_s$ of the RBC obtained from fluctuation data and that\nmeasured in static deformation experiments have the same order of magnitude. A\nsimple micromechanical model of the RBC developped for this purpose accounts\nfor the influence of a finite-thickness cytoskeleton on the fluctuations of the\ncomposite membrane-cytoskeleton system. The spectrin network cytoskeleton with\nthe bulk shear modulus estimated as $\\mu\\approx105\\div 165$ Pa contributes to\nboth normal and tangent fluctuations of the system and confines the\nfluctuations of the lipid membrane. The ratio of mean square amplitudes of the\nRBC normal and tangent fluctuations $\u003cX_n^2\u003e /\u003c X_t^2\u003e$ calculated in the frame\nof the model is 2-3 orders of magnitude smaller that it is in the free membrane\nwith the same bending and shear moduli",
