Stretch-induced force development in Mytilus smooth muscle during submaximal activation.
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.
