The mechanical action and innervation of the major flight muscles of dragonflies are described. All flight muscles investigated are innervated by at least 3 motor neurones and one by as many as 15. Cell bodies of motor neurones that innervate the same muscle are clustered together and have similar, widespread dendritic branching patterns. Motor neurones of leg muscles have greater variety in cell body size and position than the major flight motor neurones. Striking similarities between the positions of cell bodies of motor neurones in dragonflies and the positions of homologous motor neurones in other insects raise interesting questions about the evolution of insect nervous systems.
本文描述了蜻蜓主要飞行肌肉的机械作用和神经支配。所有被研究的飞行肌肉至少由3个运动神经元支配，其中一块肌肉由多达15个运动神经元支配。支配同一肌肉的运动神经元的细胞体聚集在一起，具有相似的、广泛的树突分支模式。腿部肌肉的运动神经元在细胞体大小和位置上比主要飞行运动神经元有更大的差异。蜻蜓运动神经元细胞体的位置与其他昆虫同源运动神经元的位置之间存在惊人的相似性，这引发了关于昆虫神经系统进化的有趣问题。
