This myelin is produced by oligodendrocytes, which are a group of cells that support neurons.

髓由支持神经元的少细胞形成。

They can travel more quickly if the nerve is covered in myelin.

如果神经被髓覆盖，它们可以更快地移动。

Ultimately the inflammation damages the myelin or the neurons themselves in the spinal cord.

最终造成的炎症反应会损伤脊髓神经细胞或其髓。

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

但是速度可以因髓化和增加轴直径而得到提升。

Myelin acts like insulation, just like on an electrical wire that helps the impulse travel more quickly.

髓就像绝缘体，就像电线一样，帮助脉冲更快地传播。

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

髓是一种脂肪，它把轴隔绝起来，以防止电波泄漏。

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，一种叫做髓的脂肪组织覆盖神经元的轴上。

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化和轴直径。

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

轴的某些位置可有髓包绕。

Surrounding the axon is a myelin sheath, which is actually just insulation.

轴周围是髓，实际上只是绝缘层。

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，包裹轴的髓会发生磨损，其它的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基是一种来源于非神经元细胞的结缔组织，可形成髓，使成熟神经元的轴绝缘。

The young brain is largely not myelinated. Myelin is the coating of nerve fibers that connect nerve cells.

年轻的大脑基本上没有髓。髓是连接神经细胞的神经纤维的涂层。

MRI reveals that CG has developed central pontine myelinolysis.

MRI扫描提示CG出现了脑桥中央髓溶解症。

Without myelin this signal propagation is very slow and inefficient.

如果没有髓，信号传播会非常缓慢且低效。

And an MRI of his brain reveals that JW has central pontine myelinolysis.

核磁共振影像报告显示，JW有脑桥中央髓溶解症。

Together these genetic and environmental influences might lead to the body not killing off immune cells that target myelin.

基因和环境因素的共同影响可能导致机体不能清除掉那些攻击髓的免疫细胞。

Frequently used neuronal pathways are myelinated, wrapped in a layer of insulation, allowing information to travel faster.

经常使用的神经通路是有髓的，包裹一层绝缘层中，使信息能够更快地传播。

Without oligodendrocytes, there's no myelin to cover the neurons, and this leaves behind areas of scar tissue, also called plaques or sclera.

没了少细胞，也就没有保护神经元的髓，还会留下斑痕组织（硬化斑）。

Myelin is extremely important to neurons, because it helps to allow an action potential to propagate much faster.

髓对于神经元十分重要，因为它可以极大地加速动作电位的传播。
