The distribution and morphology of the neurons innervating the lateral rectus and retractor bulbi muscles of the frog Rana ridibunda were studied by means of retrograde axonal transport of horseradish peroxidase (HRP). The neurons are located in the rhombencephalon in two distinct groups which lie dorsolateral and lateral to the fasciculus longitudinalis medialis and represent the main and accessory abducens nuclei, respectively. From HRP injections into the two muscles, it can be concluded that multipolar neurons located rostrally in the main abducens nucleus innervate the lateral rectus muscle. The retractor bulbi muscle receives its innervation from bipolar, fusiform neurons located in the caudal portion of the main abducens nucleus and throughout the rostrocaudal extent of the accessory abducens nucleus.
采用辣根过氧化物酶（HRP）逆行轴突运输法，研究了食用蛙（Rana ridibunda）支配外直肌和眼球退缩肌的神经元的分布和形态。这些神经元位于后脑，分两组，分别位于内侧纵束的背外侧和外侧，分别代表主要展神经核和副展神经核。通过向两块肌肉注射HRP，可以得出结论：位于主要展神经核前部的多极神经元支配外直肌。眼球退缩肌由位于主要展神经核尾部以及副展神经核全长的双极、梭形神经元支配。
