Length-dependent activation: its effect on the length-tension relation in cat ventricular muscle.
In cat papillary muscles at 30 degrees C, bathed with Tyrode's solution containing 2.25 mM Ca2+, the effect of various inotropic interventions (varying the stimulus frequency and continual paired stimulation) on the shape of the steady state length-tension relation was examined at lengths from Lmax, where tension production is maximal, to 0.87 Lmax. The relative steepness of the length-tension ...
متن کاملLength-tension relation in Limulus striated muscle
Laser diffraction techniques coupled with simultaneous tension measurements were used to determine the length-tension relation in intact, small (0.5-mm thick, 10-mm wide, 20-25-mm long) bundles of a Limulus (horseshoe crab) striated muscle, the telson levator muscle. This muscle differs from the model vertebrate systems in that the thick filaments are not of a constant length, but shorten from ...

متن کاملThe sarcomere length-tension relation in skeletal muscle
Tension development during isometric tetani in single fibers of frog semitendinosus muscle occurs in three phases: (a) in initial fast-rise phase; (b) a slow-rise phase; and (c) a plateau, which lasts greater than 10 s. The slow-rise phase has previously been assumed to rise out of a progressive increase of sarcomere length dispersion along the fiber (Gordon et al. 1966. J. Physiol. [Lond.]. 18...
متن کاملLength-dependent calcium inotropism in cat papillary muscle.
We studied changes in the relationship of isometric developed force to muscle length when extracellular calcium concentration was altered in isolated cat papillary muscles. In two series of experiments at temperatures of 30 degrees C and 32 degrees C, and rates of 12 and 30 beats/min, 21 muscles were exposed to calcium concentrations of 1.125, 2.25 and 4.5 mM. Muscle lengths were varied between...
