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。

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

神经在轴突中传输的速度较慢， 最多 100 米每秒。

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的轴突上。

Can we grow axons and neurons down these channels?

我们能否沿着这 培植神经轴突或神经呢?

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

，tau要支撑称为微管即存在于轴突中的小管。

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

受损的神经重新长出长的信号尾，这个便是轴突。

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

每一个毛细胞都附着在神经系统的轴突上。

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。

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。

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

它们过电子脉冲或动作电位把信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，包裹轴突的髓鞘质会发生磨损，其它的神经结构也会衰退。

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细胞的结缔组织，可形成髓鞘，使成熟神经的轴突绝缘。

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

轴突的某位置可有髓鞘在外包绕。

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。

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

树突、胞体和轴突。

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

髓鞘质是一种脂肪鞘，它把轴突隔绝起来，以防止电波泄漏。

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，一种是向其他神经传递信号的轴突。

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

这细胞的信号传递臂被称为轴突，最长可达一米！

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

这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。

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。
