在横管系统被破坏的肌肉纤维上记录到没有伴随收缩的动作电位。结果表明，动作电位需要完整的横管系统才能引起收缩。此外，单一动作电位之后的后去极化和一系列动作电位之后较慢的后期后电位在这种制备中都没有。因此，这两种现象通常都与横管系统有关。
Action potentials, with no accompanying contraction, were recorded from muscle fibers in which the transverse tubular system was disrupted. The results show that action potentials require an intact transverse tubular system to cause contraction. Furthermore, both the after-depolarization following a single action potential and the slower, late afterpotential following a train of action potentials were absent in this preparation. Therefore, both phenomena must normally involve the transverse tubular system.
