When the anterior byssal retractor muscle of Mytilus edulis is stretched by 5-20% during submaximal activation with 100 mM K+ or 10(-5) M acetylcholine, it exhibited a delayed force development after the completion of stretch. The effect of ions and drugs on the stretch-induced activation suggests the stretch-induced release of Ca2+ from the inner surface of the plasma membrane.
当紫贻贝的前足丝牵缩肌在100 mM K⁺或10⁻⁵ M乙酰胆碱进行次最大激活时被拉伸5 - 20%,它在拉伸完成后表现出延迟的力发展。离子和药物对拉伸诱导激活的影响表明,Ca²⁺从质膜内表面被拉伸诱导释放。
