Age-related changes in motor endplates were studied in the fibularis longus, semitendinosus and longissimus muscles in pigs. They develop from small, compact AChE-active figures in fetuses to typical myoneuronal synapses with a branched subsynaptical structure of AChE-active units. High correlations were found between size of endplates and both myofibre diameter and body mass. Growth analyses with respect to age, as well as allometrical approaches, showed that endplate growth slightly precedes that of myofibres, with both having similar growth patterns. The morphological changes, however, imply that the increment of synaptical area could lag behind that of myofibres.
研究了猪的腓骨长肌、半腱肌和最长肌中运动终板的年龄相关变化。它们从胎儿期小而紧密的乙酰胆碱酯酶活性图形发展为具有乙酰胆碱酯酶活性单位分支状突触下结构的典型肌神经元突触。发现终板大小与肌纤维直径和体重之间存在高度相关性。关于年龄的生长分析以及异速生长方法表明，终板生长略先于肌纤维生长，两者具有相似的生长模式。然而，形态学变化表明突触面积的增加可能落后于肌纤维。
