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。

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。

This hypoxia also causes the parasympathetic nerve fibers to die off.

这种缺氧还会导致交感神经纤维死亡。

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。

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脑干连接地方。

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，在最大血管中也有弹性蛋白。

In both cases, the parasympathetic nerve fibers in the cavernosal spaces release acetylcholine from their nerve endings.

在这两种情况下，交感神经纤维在海绵体间隙通过神经末梢释放乙酰胆碱。

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，最终成为肠神经丛神经纤维。

And finally, the nerve fibers themselves have different structures.

最后，神经纤维本身有不同结构。

Damaged parasympathetic nerve fibers can't release acetylcholine, so there's less nitric oxide synthase activation, and less nitric oxide is produced.

受交感神经纤维不能释放乙酰胆碱，因此被激活一氧化氮合酶较少，产生一氧化氮也较少。

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。

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。

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

但是交感神经系统神经纤维是从交感神经上方和下方开始。

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外周感受器，而是直接刺激神经纤维。

Myelin is an insulator and speeds up the electrical signals zipping down the nerve fiber.

髓磷脂是一种绝缘体，可加快电信号在神经纤维中传输速度。

The two hemispheres are connected by a bundle of nerve fibers called the corpus callosum.

这两个半球由一束叫做胼胝体神经纤维连接。

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

它们胡须，或触须，由角蛋白组成，富含神经纤维，神经纤维深入其脸部结缔组织。

If nerve fibers are activated repeatedly, the brain may decide they need to be more sensitive to adequately protect the body from threats.

如果反复激活神经纤维，大脑可能会决定它们需要更敏感以充分保护身体免受威胁。

Treatment is typically surgical resection of the area that's lacking the nerve fibers, and then the healthy end is connected to the anus.

治疗疾病一般行根治手术，切除神经纤维缺失肠段，然后将剩余肠段健康一端连肛门。

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

神经纤维，包括从别神经元接收信号树突，和向别神经元发送动作电位信号轴突。
