Responses of skeletal muscle fibres to lanthanide ions. Dependence of the twitch response on ionic radii.
A study of the effects of the lanthanide series of ions on toad skeletal muscle fibres reveals that they a) inhibit the twitch response, b) exhibit a marked dependence on ionic radius, and c) apparently exert their effects on the sarcolemma.
