I mean, we're talking about the autonomic system here, but they are not all autonomic motor fibers.

我的意思是，我们在这里讨论的是自主神经系统，但它们并不都是自主运动纤维。

Some of your cranial nerves also carry motor fibers that control voluntary functions, like moving your eyeballs around.

你的一些脑神经还携带运动纤维，控制自发功能，比如移动眼球。

And it's rich in motor fibers that travel from the cortex on the left side of your brain to muscles on the right side of your body.

此处有许多从大脑左侧皮层发出的支配身体右侧肌肉的神经纤维。
