Since the trigeminal and sacral nuclei serve just one side of the face or body, herpes vesicles and ulcers develop on the ipsilateral or same side as the affected nuclei.

因为三叉神经核和骶神经核只支配脸部或身体的一侧，所以，疱疹和溃疡也发生在被感染的神经核的同侧。

The one huge difference is that there's another upper motor neuron that extends down from a region in the right motor cortex, and stays on the ipsilateral or same side to meet with same the lower motor neuron.

有一点很不同，即面部右上部分，还有右侧运动皮质发出的上运动神经元，在同侧走行，并与下运动神经元交汇。
