The excitation is passed to a nerve fiber, and then propagates into the brain.

这种兴奋传递给神经纤维，随后传导进大脑。

But it's not because fingers have more nerve fibers.

但这并不是因为手指部分汇更多神经纤维的缘故。

And the speed of those signals varies with the fiber's thickness.

这些信号的速度神经纤维的厚度有关。

Meanwhile, some NF treatments have entered clinical trials in China.

此同时，一些神经纤维瘤病疗法已经在中国进入临床试验。

That's where the auditory nerve fibers that encode information about sound connect to the brain stem.

这里是编码声音信息的听觉神经纤维脑干连接的地方。

And finally, the nerve fibers themselves have different structures.

最后，神经纤维本身有不同的结构。

" Point" is erection and it's caused by " P, " or parasympathetic fibers.

“Point”代表勃起，它是由“P”副交感（parasympathetic）神经纤维引起的。

The tunica externa also has nerve fibers, lymphatic vessels, and in the biggest vessels, the protein elastin.

外膜也有神经纤维、淋巴管，在最大的血管中也有弹性蛋白。

From there, the postganglionic fibers are super short — just long enough to communicate with their effector.

从那里，节后神经纤维超短——刚好足够它们的效应器交流。

All of these receptors work by sending electrical signals to the brain through fibers they're attached to.

所有这些感受器通过向大脑发送电信号来工作，经由所依附的神经纤维。

Medical experts noted that a drug for certain neurofibromatosis patients could be available in 2024.

医学专家指出，2024 年可能会有一种用于某些神经纤维瘤病患者的药物。

In this case, some of them become neuroblasts, and eventually the nerve fibers of the plexuses in the gut.

在这种情况下，其中一些变成了神经母细胞，最终成为肠神经丛的神经纤维。

But the nerve fibers of your parasympathetic system begin both above and below where the sympathetic ones do.

但是副交感神经系统的神经纤维是从交感神经的上方和下方开始的。

This leads to dysfunction of the median and ulnar nerves since they contain fibers from these roots.

这会造成正中尺神经功能障碍，因为这两条神经含有来自C8、T1神经根的神经纤维。

So, the preganglionic fiber releases ACh, and the postganglionic releases norepinephrine.

所节前神经纤维释放 ACh，节后神经纤维释放去甲肾上腺素。

Through this network of nerve connections, your big brain communicates stress to your enteric, or intestinal nervous system.

通过这个系统中神经纤维间的联系，你的大脑向你的肠道，或者说肠神经系统传递了压力的信号。

For example, some nociceptors are attached to fibers with slightly more conductive, fatty myelin than others.

例如，有些伤害感受器依附于神经纤维，就会更具有传导作用，髓磷脂所富含的脂肪也更多一些。

There are close to one million nerve fibres that connect the eyeball to the brain.

眼球和大脑之间有近百万神经纤维。

Our patient has a 200 pound neurofibroma.

- 我们的患者患有 200 磅重的神经纤维瘤。

The neurofibroma started as a small bump, near the base of the spine.
