Muscle contraction is a three-dimensional process, as anyone who has observed a bulging muscle knows. Recent studies suggest that the three-dimensional nature of muscle contraction influences its mechanical output. Shape changes and radial forces appear to be important across scales of organization. Muscle architectural gearing is an emerging example of this process.
肌肉收缩是一个三维过程,这是任何观察过肌肉鼓起的人都知道的。最近的研究表明,肌肉收缩的三维性质会影响其机械输出。在组织的不同尺度上,形状变化和径向力似乎都很重要。肌肉建筑齿轮是这个过程的一个新例子。
