用细胞内注射法将辣根过氧化物酶注入猫三头肌表面。通过光镜和电镜对运动神经元、运动轴突和循环运动轴突侧支及其突触末梢进行了追踪。除了预期的投射到Renshaw细胞区域外，三头肌表面运动轴突侧支经常终止于运动核内，其中至少有一些末端与三头肌表面运动神经元直接突触接触。
By using intracellular injection of horseradish peroxidase into cat triceps surae .alpha.-motoneurons the motor axons and the recurrent motor axon collaterals with their synaptic terminals were traced by light microscopy and EM. In addition to the expected projection to the Renshaw cell area, the triceps surae motor axon collaterals frequently terminated within the motor nuclei, where at least some of the terminals made direct synaptic contact with triceps surae .alpha.-motoneurons.
