The arrangement of the motoneurons innervating the supramandibular and suprahyoid muscles was studied in Wistar albino rats using two fluorescent tracers: nuclear yellow and true blue. All supramandibular motoneurons were found within the trigeminal motor nucleus; they appeared to be somatotopically arranged. The suprahyoid motoneurons were located in an accessory trigeminal-facial motor complex. No overlap of the motoneuron pools of the supramandibular and suprahyoid muscle group was observed. Only motoneurons ipsilateral to the treated muscles were labeled. It was shown that a one-to-one relationship always exists between motoneuron and muscle.
核黄和真蓝，在Wistar白化大鼠中研究了支配下颌上和舌骨上肌肉的运动神经元的排列。所有支配下颌上肌肉的运动神经元均位于三叉神经运动核内；它们似乎呈躯体定位排列。舌骨上运动神经元位于一个副三叉-面神经运动复合体中。未观察到下颌上和舌骨上肌肉组运动神经元池的重叠。仅处理侧肌肉同侧的运动神经元被标记。结果表明，运动神经元与肌肉之间始终存在一对一的关系。
