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

这种兴奋状态被传递给神经纤维，随传导进大脑。

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

这些信号速度与神经纤维厚度有关。

3.Your ulnar nerve is composed of both sensory and motor nerve fibers.

尺神经由感觉神经和运动神经纤维组成。

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

但这并不是因为手指部分汇集更多神经纤维缘故。

5.And finally, the nerve fibers themselves have different structures.

，神经纤维本身有不同结构。

6.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神经纤维与脑干连接地方。

7.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药物。

8.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，在大血管中也有弹性蛋白。

9.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，经由所依附神经纤维。

10.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，终成为肠神经丛神经纤维。

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

与此同时，一些神经纤维瘤病疗法已经在中国进入临床试验。

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

所以节前神经纤维释放 ACh，节神经纤维释放去甲肾上腺素。

13.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联系，你大脑向你肠道，或者说肠神经系统传递了压力信号。

14.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，髓磷脂所富含脂肪也更多一些。

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

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

16.Nerve fibers are either dendrites that receive signals from other neurons, or axons that send signals along to other neurons.

神经纤维分为两种，一种是接收信号树突，一种是向其他神经元传递信号轴突。

17.Papilledema is the swelling of the optic disc, which is the point where the optic nerve fibers leave the retina.

视神经乳头水肿是指视盘肿胀，视盘是视神经纤维离开视网膜部位。

18.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。

19.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神经纤维是从交感神经上方和下方开始。

20.Those are the different types of neurofibromas, by the way, that were popping up.

- 顺便说一下，这些是不同类型神经纤维瘤。机翻
