Intracellular calcium movements during excitation–contraction coupling in mammalian slow-twitch and fast-twitch muscle fibers
In skeletal muscle fibers, action potentials elicit contractions by releasing calcium ions (Ca(2+)) from the sarcoplasmic reticulum. Experiments on individual mouse muscle fibers micro-injected with a rapidly responding fluorescent Ca(2+) indicator dye reveal that the amount of Ca(2+) released is three- to fourfold larger in fast-twitch fibers than in slow-twitch fibers, and the proportion of t...
متن کاملTime- and Na-dependent effects of Ca depletion on potassium contracture in frog twitch muscle fiber.
The effect of the extracellular Ca depletion on potassium contracture was investigated in single fibers isolated from frog semitendinosus muscle mainly in relation to its time and Na dependency. The shortening of plateau duration and the increase in the rate of relaxation of the potassium contracture appeared within 3--5 sec and 15 sec, respectively, after the fiber was immersed in Ca-free Na R...
متن کاملStretch-induced contraction of intrafusal muscle in cat muscle spindle.
Measurements of tension, stiffness, and sarcomere length of intrafusal muscle during ramp stretch of isolated muscle spindles have revealed a stretch-induced contraction of the bag1 fiber. This behavior can account for the very high sensitivity of primary endings to stretch as well as the enhanced sensitivity evoked by dynamic fusimotor stimulation.
متن کاملCyclic GMP-dependent protein kinase signaling pathway inhibits RhoA-induced Ca2+ sensitization of contraction in vascular smooth muscle.
The potent vasodilator action of cyclic GMP-dependent protein kinase (cGK) involves decreasing the Ca(2+) sensitivity of contraction of smooth muscle via stimulation of myosin light chain phosphatase through unknown mechanisms (Wu, X., Somlyo, A. V., and Somlyo, A. P. (1996) Biochem. Biophys. Res. Commun. 220, 658-663). Myosin light chain phosphatase activity is controlled by the small GTPase R...
متن کاملInhibition and synchronisation of tremor induced by a muscle twitch.
The effects of a muscle twitch on the tremor of the extensor indicis muscle and of the tibial anterior muscle have been recorded in 14 patients with essential tremor and in 10 patients with Parkinson's disease. The muscle twitch evoked by the electrical stimulation of the motor nerve inhibits the tremor and synchronises it. The mean duration of the inhibition is 92.1 +/- 6.8 ms for essential tr...
