Tension transients were recorded in a single smooth muscle cell. The transient contains a linear elastic response and a biphasic recovery that appear to originate from the cross-bridges. A comparison of transients in smooth and fast skeletal muscle fibers suggests that the cross-bridge in smooth muscle is more compliant than the cross-bridge in striated muscle and that transitions between several cross-bridge states occur more slowly in smooth muscle than in striated muscle.
在单个平滑肌细胞中记录到了张力瞬变。该瞬变包含一个线性弹性反应和一个双相恢复，这似乎源于横桥。平滑肌纤维和快速骨骼肌纤维中瞬变的比较表明，平滑肌中的横桥比横纹肌中的横桥更具柔韧性，并且平滑肌中几种横桥状态之间的转变比横纹肌中发生得更慢。
