摘要

当肌动蛋白和肌球蛋白丝从其等距位置位移10-12纳米时,活动的整块肌肉的拉伸引起肌节的突然屈服。这种行为通常不会在单解剖纤维拉伸过程中出现,但可以通过在系统中引入串联顺应性来诱导。

Sarcomere 'give' during stretch of frog single muscle fibres with added series compliance.

Stretch of active whole muscle causes a sudden yielding of the sarcomeres when the actin and myosin filaments are displaced by 10-12 nm from their isometric position. This behaviour is not normally seen during stretch of singly-dissected fibres, but it can be induced by introducing series compliance into the system.
