Beschreibung:that in all statistical calculations we only have derived most probable i.e. average quantities and did not care about their fluctuations which in principle could also be evaluated. In this paper the meander model of muscle is proposed (e.g. geometries, forces) and treated quantitatively. The geometries of myosin and uninterrupted actin filaments as well as of the Z zone in vertebrate striated muscle are derived from thermodynamic equilibrium considerations. Crossbridges formed by the myosin projections and the actin meander folds are considered either to be loose or closed. Mg A TP action enables them to rearrange forces and removes, therefore, the The proposed meander model of muscle is suitable to explain active as well as passive difficulties. cyclically. The closed bridges give rise to a thermodynamic inherent in Huxleys sliding filament model. . contractive force on the actin filament. Also passive and We cannot exclude, however, that there is a active stress-strain behaviour (under isometrie conditions) agree with experiment. small contribution to the passive elastic behaviour from elements (e.g. membranes) in Zusammenfassung parallel to the sliding filament system
