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，随后传导进大脑。

STEP 5 Mix water with the milk of magnesia and gargle twice daily. Coating the tongue with milk of magnesia stimulates touch and taste receptors, which inhibit pain nerve fibers.

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

这并不是因为手指部分汇集更多神经纤维的。

But while this extensive network is constantly sending signals from the brain to your body, scientists have noted that 80-90% of the nerve fibers in the enteric nervous system are actually going from the gut to the brain.

是，当这个大规模的网络不断地从大脑向身体发送信号时，科学家们注意，肠道神经系统中80-90%的神经纤维实际上是从肠道大脑的。

Each one of your different skeletal muscles — like your biceps brachii, or vastus lateralis or gluteus maximus — is technically its own organ, made up mostly of muscle tissue, but also of connective tissue, blood vessels, and nerve fibers.

你的每一块不同的骨骼肌——比如肱二头肌、股外侧肌或臀大肌——严格来说都是自己的器官，主要由肌肉织，也由结缔织、血管和神经纤维。

But researchers at the Johns Hopkins School of Medicine say close examination of the brains of veterans who died of other causes shows a pattern of swollen and broken nerve fibers concentrated in the frontal lobe.

约翰霍普金斯大学医学院的研究人员表示仔细检查死于其他原因退伍军人的大脑显示肿胀及破碎的神经纤维集中在额叶部分。

In addition, the cells of a poorly differentiated neuroblastoma may be surrounded by a substance called neuropil, which is a dense network of interwoven nerve fibers, like axon and dendrite branches.

分化不良型神经母细胞瘤的细胞可能被神经纤维网包围，即由轴突和树突分支等神经纤维交织的密集网状结构。

That's the stage when individuals usually experience pain, although pain can also occur when the caries lesion involves the dentin layer since sensory nerve fibers travel through tubules in the dentin.

在这个阶段，患者常会感疼痛，牙本质层受累产生龋坏时也可能有疼痛产生，因为感觉神经也分布在牙本质的管道中。

This ischemia is thought to trigger release of adenosine, bradykinin, and other molecules that stimulate nerve fibers in the myocardium that result in the sensation of pain.

心内膜下缺血被认为启动腺苷、缓激肽等分子的释放，这些分子刺激心肌层神经末梢，导致痛觉产生。

They're composed of a cell body, which contains all the cell's organelles, and nerve fibers, which are projections that extend out from the neuron cell body.

神经元由包含所有细胞器的胞体和从胞体发出的传递信号神经纤维。

More stress sensors can be added to nerve fibers until they become so sensitive that even light touches to the skin spark intense electrical signals.

可以将更多的压力传感器添加神经纤维中，直它们变得非常敏感，甚至光接触皮肤也会产生强烈的电信号。

Instead of the sensation simply activating peripheral receptors that send electrical signals along your ulnar nerve, the nerve's fibers are stimulated directly.

这种感觉不是简单地激活沿尺神经发送电信号的外周感受器，而是直接刺激神经纤维。

The stomach and brain also communicate through the vagus nerve, an intricate network of nerve fibers which run between the brain and the abdomen.

胃和大脑还通过迷走神经进行通信，迷走神经是大脑和腹部之间运行的复杂神经纤维网络。

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。

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。

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与脑干连接的地方。

And finally, the nerve fibers themselves have different structures.

最后，神经纤维本身有不同的结构。

A disruption of that neuroblast journey in that time window, means that nerve fibers don't develop in the rectum and parts of the colon.

（假如那时）神经母细胞的旅程被中断，意味着神经纤维不能在直肠和部分结肠中形。

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，一种是接收信号的树突，一种是向其他神经元传递信号的轴突。

Their whiskers, or vibrissae, are composed of keratin and full of nerve fibers that run deep into the connective tissue of their face.
