To investigate the relationship between motor endplate size and muscle fiber diameter, analyses of 125I-alpha-bungarotoxin autoradiographs and acetylcholinesterase staining were performed in different muscle groups of the rat. These revealed 1) there is a linear correlation between endplate size and fiber diameter in each muscle group, and 2) each muscle group has a characteristic ratio of endplate size to fiber diameter; the ratios were markedly higher in extraocular muscles than in limb muscles.
为了研究运动终板大小与肌纤维直径之间的关系，我们对大鼠不同肌肉组进行了¹²⁵I-α-银环蛇毒素放射自显影片分析和乙酰胆碱酯酶染色。结果显示：1）每个肌肉组中终板大小与纤维直径之间存在线性相关性；2）每个肌肉组都有终板大小与纤维直径的特征性比值；眼外肌的比值明显高于肢体肌肉。
