骨骼肌收缩张力传递方式的研究现状

The Current Situation of Studying the Force Transmission in Skeletal Muscle

近年来的研究表明，骨骼肌收缩张力可沿肌纤维轴的任意一个方向传递。张力既可沿肌节纵向传递，也可在肌节间通过中介微丝系统横向传递。肌肉张力传递的复杂路径将是生理与肌肉力学研究的重要课题。

The current studies show that the muscle force can be transmitted practically any direction with respect to the fiber axis. Force is transmitted serially between sarcomeres but also laterally by the intermediate filament system. This complex pathway will be the subject to future studies in physiology and muscle biomechanics.
