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——电信号可以沿其传播。

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

神经元在轴突中传输速度慢， 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，一种叫做髓鞘脂肪组织覆盖在神经元轴突上。

Meanwhile, axons with larger diameters offer less internal resistance.

同时，直径轴突拥有小内部阻力。

Can we grow axons and neurons down these channels?

们能否沿着这些通道 培植神经轴突或神经元呢?

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

受损神经元重新出信号尾，这个便是轴突。

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。

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

这些细胞信号传递臂被称为轴突，最可达一米！

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，使成熟神经元轴突绝缘。

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。

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统轴突上。

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小管。

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，包裹轴突髓鞘质会发生磨损，其它神经元结构也会衰退。

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

树突、胞体和轴突。

The white matter consists of myelinated axons, which are separated into tracts that carry information to and from the brain.

白质由有髓鞘轴突组成，它们被分成若干神经束，负责向大脑传递以及从大脑向其他部位传递信息。

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髓和节前神经轴突。

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保护性鞘膜，能快速传导神经冲动。

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

髓鞘质是包绕在周围神经轴突上保护性鞘，使轴突可以快速传递电冲动。

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。

Then, once the voltage reaches a specific threshold, a pulse is fired along organic amplifiers that mimic a nerve cell axon.

之后电压一旦到达特定值，就会沿着模拟神经细胞轴突有机放大器释放脉冲。
