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

神经元在中传输速度较慢， 最多 100 米每秒。

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。

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

受损神经元重新长出长信号尾，是。

Can we grow axons and neurons down these channels?

我们能否沿着些通道 培植神经或神经元呢?

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

大脑发送动作电位到脊髓和节前神经。

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

还会注意到它们有长长——电信号可以沿其传播。

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

当重复一动作时，一种叫做髓鞘脂肪组织覆盖在神经元上。

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

些细胞信号传递臂被称为，最长可达一米！

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

信号被下一神经元神经树接收，下传到它神经，然后接着传递下去。

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

树、胞体和。

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

神经中开始死亡。肌肉无法被控制，因此它们会萎缩。

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

髓磷脂是神经周围保护性鞘膜，能快速传导神经冲动。

The demyelination happens in patches along the length of the axon, so it's called segmental demyelination.

因为上只发生局限性脱髓鞘，因此又称为节段性脱髓鞘。

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

但是速度可以因髓鞘化和增加直径而得到提升。

Myelin is a fatty sheath that insulates an axon, preventing electrical currents from leaking out.

髓鞘质是一种脂肪鞘，它把隔绝起来，以防止电波泄漏。

Meanwhile, axons with larger diameters offer less internal resistance.

同时，直径较长拥有较小内部阻力。

Schwannian stroma is a connective tissue from non-neuronal cells that forms myelin, which insulates the axons of the mature neurons.

Schwannian基质是一种来源于非神经元细胞结缔组织，可形成髓鞘，使成熟神经元绝缘。

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

某些位置可有髓鞘在外包绕。

There's no axons, no neurons. It doesn't get depressed.

没有， 没有神经元。它不会变得沮丧。

So normally those axons would die  off, and the mice would be blind.

所以通常那些会死亡，小鼠就会失明。
