Structural changes in the muscle thin filament during contractions caused by single and double electrical pulses.

Abstract

In order to investigate the structural changes of the myofilaments involved in the phenomenon of summation in skeletal muscle contraction, we studied small-angle x-ray intensity changes during twitches of frog skeletal muscle elicited by either a single or a double stimulus at 16 degrees C. The separation of the pulses in the double-pulse stimulation was… (More)
