Conclusions So that this paper concludes that co-contraction contributes to impedance control even during free upper limb planar movement.
结论即使在手臂平面自由运动中，肌肉共同收缩对阻抗也有贡献。

An electrical wave traverses the heart each time it beats, co-ordinating the contraction and relaxation of the chambers that pump blood around the body.
随着心室的收缩和舒张将血汞到了全身，心脏跳动一次，电波横穿心脏一次。
