Electron micrographs of guinea-pig oesophageal striated muscle have been subjected to quantitative assessment. The results show that whereas the motor end-plates are considerably simpler than those of control hindlimb muscles, the Z-line width and M-line bridges are those of fast-twitch, oxidative and glycolytic fibres. Guinea-pig oesophageal striated muscle continues to defy classification into the normally accepted subtypes for skeletal muscle and should thus be considered as an example of 'visceral striated muscle'.
豚鼠食管横纹肌的电子显微镜照片已接受定量评估。结果表明，虽然运动终板比对照后肢肌肉的运动终板要简单得多，但Z线宽度和M线桥却是快肌纤维、氧化型纤维和糖酵解型纤维的特征。豚鼠食管横纹肌仍然难以被归类为骨骼肌通常公认的亚型，因此应被视为“内脏横纹肌”的一个例子。
