Staining for motor endplates and chemical digestion of five major muscles of the domestic chicken shows that these confirm the short-fibre strap muscle paradigm. The individual fibres are spindle-shaped, terminating in gradually tapering ends. The motor endplates of the individual fibres align in cross-bands along the length of the fascicles. These bands are spaced much more tightly than are comparable bands in mammals; unlike the condition in mammals, many fibres are longer than twice the interband spacing. The spacings between bands differ by more than a factor of five along the length of each muscle. The proportions among bands remain relatively constant. These proportions are not affected by the degree of muscular contraction, nor do they change with ontogeny, suggesting that the arrangement is established before hatching.

鸡肌肉的结构：短纤维形态及其个体发育。

对运动终板进行染色和对家禽的五种主要肌肉进行化学消化的结果表明，这些证实了短纤维带状肌肉的范例。各个纤维为纺锤形，终止于逐渐变细的末端。单个纤维的电动机端板沿束的长度成交叉带对齐。这些条带的间隔比哺乳动物中的类似条带要紧密得多。与哺乳动物的情况不同，许多纤维的长度大于带间间隔的两倍。沿着每条肌肉的长度，乐队之间的距离相差五倍以上。频段之间的比例保持相对恒定。这些比例不受肌肉收缩程度的影响，也不会随个体发育而改变，这表明在孵化之前就已经建立了该比例。
