Neuromuscular transmission and excitation-contraction coupling in fish red muscle.
TAKEUCHI (1959) has studied on red and white muscle fibres of fresh water fish teleost (snake fish) and observed that (1) there was no difference between the membrane potential of the red muscle and that of white one (60-70mV) , (2) the red muscle did not generate the spike but did only junction potential, (3) the white muscle generated the spike but usually did not overshoot the resting potent...
متن کاملEffects of Buthus eupeus Venom on Neuromuscular Transmission on Striated Muscle In Vitro
In this study, effects of Buthus eupeus venom on chick biventer cervices nerve-muscle preparation were investigated by twitch tension method. The venom, at 1.3 ?g/ml, increased contractile responses in indirect stimulations. These effects were milder in direct muscle stimulations. It also caused significant enhancement in postjunctional sensitivity as assessed by responses to exogenous acetylch...

متن کاملInhibitory action of Ruthenium red on neuromuscular transmission.
The effect of Ruthenium Red on synaptic transmission was examined at isolated junctions of the frog, by conventional methods for stimulation and intracellular recording. Ruthenium Red (2.5-10.0 muM) reduces the synaptic potential to subthreshold levels. An analysis of this phenomenon shows that the main action of Ruthenium Red is on the presynaptic nerve terminal where it decreases the number o...
