A neuron has three parts: Dendrites, soma or cell body, and axon.

树突、胞体和轴突。

Axon serve as output device from where it transmit electrical response to other neurons.

轴突作为输出装置，将电反应传递给其他神经元。

Can we grow axons and neurons down these channels?

我们能否沿着这些通道 培植神经轴突或神经元呢?

The axons are intermittently wrapped in a fatty substance called myelin.

轴突的某些位置可有髓鞘在外包绕。

The damaged neurons regrew their long signaling tails, called axons.

的神经元重新长出长的信号尾，这个便是轴突。

Neurons propagate slowly in axons, 100 meters per second, tops.

神经元在轴突中传输的速度较慢， 最 100 秒。

Usually, tau proteins support tiny tubes inside our axons called microtubules.

通常，tau蛋白要支撑称为微管即存在于轴突中的小管。

Each of these hair cells is attached to axons in the nervous system.

一个毛细胞都附着在神经系统的轴突上。

The signal-carrying arm of these cells, called an axon, can be up to a meter long!

这些细胞的信号传递臂被称为轴突，最长可达一！

You will also notice they have long axons along which the electrical message can travel.

你还会注意到它们有长长的轴突——电信号可以沿其传播。

They transmit signals down their axons by way of electrical impulses, or action potentials.

它们通过电子脉冲或动作电位把信号向下传递给神经轴突。

Axons in the nerves begin to die off. Muscles can't be controlled, and they shrink as a consequence.

神经中的轴突开始死亡。肌肉无法被控制，因此它们会萎缩。

As you repeat an action, a fatty tissue called myelin covers the axons of your neurons.

当你重复一个动作时，一种叫做髓鞘的脂肪组织覆盖在神经元的轴突上。

The speed at which these thoughts occur is mostly consistent, with variations based on myelination and axon diameter.

这些思维的产生速度大体上是一致的，其间的区别主要基于髓鞘化和轴突直径。

Myelin is the protective sheath that surrounds the axons of neurons, allowing them to quickly send electrical impulses.

髓磷脂是神经轴突周围的保护性鞘膜，能快速传导神经冲动。

This method allows scientists to find large axon bundles and see how milder blows might alter them structurally.

这个方法可以让科学家看到大束轴突以及轻微的波动会如何改变它们。

Meanwhile, axons with larger diameters offer less internal resistance.

同时，直径较长的轴突拥有较小的内部阻力。

Your brain sends action potentials down your spinal cord and preganglionic neuronal axons.

你的大脑发送动作电位到你的脊髓和节前神经轴突。

But speeds can be boosted with myelination and increased axon diameter.

但是速度可以因髓鞘化和增加轴突直径而得到提升。

The signal is received by the next neuron's dendrites, propagated down its axon, and passed further along.

信号被下一个神经元的神经树突接收，下传到它的神经轴突，然后接着传递下去。
