Meanwhile, axons with larger diameters offer less internal resistance.

同时，直径较轴突拥有较小内部阻力。

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

神经元轴突中传输速度较慢， 最多 100 米每秒。

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

但是速度可以因化和增加轴突直径而得到提升。

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

受损神经元重新出号尾，这个便是轴突。

Can we grow axons and neurons down these channels?

我们能否沿着这通道 培植神经轴突或神经元呢?

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

轴突某位置可有外包绕。

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

你大脑发送动作电位到你脊和节前神经轴突。

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

你还会注意到它们有轴突——电号可以沿其传播。

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，一种叫做脂肪组织覆盖神经元轴突上。

Surrounding the grey matter is white matter, which consists of the myelinated axons of various neurons.

灰质周围是白质，由有神经元轴突构成。

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

因为轴突上只发生局限性脱，因此又称为节段性脱。

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

这细胞号传递臂被称为轴突，最可达一米！

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

树突、胞体和轴突。

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波动会如何改变它们。

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

这思维产生速度大体上是一致，其间区别主要基于化和轴突直径。

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

神经中轴突开始死亡。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.

磷脂是神经轴突周围保护性膜，能快速传导神经冲动。

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号向下传递给神经轴突。

In particular, as you reach old age, the myelin sheath covering your axons wears down, and other neuronal structures degrade.

特别是，当你年纪大了以后，包裹轴突质会发生磨损，其它神经元结构也会衰退。

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，使成熟神经元轴突绝缘。
