通过光学衍射揭示的肌肉横桥行程与活动

Science. 1978 Mar 17;199(4334):1212-3. doi: 10.1126/science.415364.

Optical diffraction measurements during rapid releases of active toad muscle show that the sarcomeres contract within 1 millisecond by an amount up to but not greater than 12 nanometers. This crossbridges immediately start cycling to produce the normal contraction velocity in unloaded muscle.

对活动的蟾蜍肌肉进行快速释放过程中的光学衍射测量表明，肌节在1毫秒内收缩的幅度可达但不超过12纳米。这种横桥立即开始循环，以在无负荷肌肉中产生正常的收缩速度。
