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

这种兴奋状态被传递给经，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经缘故。

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

这些信号速度与经厚度有关。

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

与此同时，一些经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听觉经与脑干连接地方。

And finally, the nerve fibers themselves have different structures.

最后，经本身有不同结构。

" 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）经引起。

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

外膜有经、淋巴管，在最大血管中有弹性蛋白。

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

从那里，节后经超短——刚好足够长以与它们效应器交流。

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，经由所依附经。

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经瘤病患者药物。

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，其中一些变成了经母细胞，最终成为肠经丛经。

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

但是副交感经系统经是从交感经上方和下方开始。

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

这会造成正中与尺经功能障碍，因为这两条经含有来自C8、T1经根经。

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

所以节前经释放 ACh，节后经释放去甲肾上腺素。

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

通过这个系统中经间联系，你大脑向你肠道，或者说肠经系统传递了压力信号。

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经，就会更具有传导作用，髓磷脂所富含脂肪更多一些。

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经。

Our patient has a 200 pound neurofibroma.

- 我们患者患有 200 磅重经瘤。

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

- 经瘤一开始是一个小肿块，靠近脊柱底部。
