Axons innervating the dorsal longitudinal flight muscle of Drosophila were investigated with physiological, light microscopic and electron microscopic techniques. Five motor axons innervate the six muscle fibres which compose a dorsal longitudinal flight muscle. All five axons, designated 1-5, are identified physiologically and morphologically. Axons 1-4 separately innervate muscle fibres 1-4, while axon 5 innervates both muscle fibres 5 and 6, making five motor units. The branching pattern of the nerve and the organization of these axons within the nerve is very consistent from fly to fly, making identification of every axon possible in both the nerve trunk and finer branches. Morphologically, axons 1-2 and 3-4 make particular pairs with long shared pathways. Furthermore, the axons are unusually closely associated with each other within the nerve.
利用生理学、光学显微镜和电子显微镜技术，对支配果蝇背纵飞行肌的轴突进行了研究。五条运动轴突支配构成一块背纵飞行肌的六条肌纤维。所有五条轴突，分别命名为1 - 5，在生理和形态上都已明确。轴突1 - 4分别支配肌纤维1 - 4，而轴突5支配肌纤维5和6，形成了五个运动单位。神经的分支模式以及这些轴突在神经内的组织方式在不同果蝇个体间非常一致，使得在神经干和更细的分支中都能够识别每一条轴突。在形态学上，轴突1 - 2和3 - 4形成了具有长共享路径的特定配对。此外，轴突在神经内彼此异常紧密地相连。
