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

如果被髓鞘覆盖，它们可以更快地移动。

Many research teams are studying how to repair myelin in MS patients.

很多试验团队正在研究如何修复MS患者的髓磷脂。

The problems included a decrease in the production of myelin.

包括髓磷脂产量的下降。

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

髓鞘由元的少突胶质细胞形成。

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元的轴突上。

For example, some nociceptors are attached to fibers with slightly more conductive, fatty myelin than others.

例如，有些伤害感受器依附于纤维，就会更具有传导作用，髓磷脂所富含的脂肪也更多一些。

Absence of myelin sheath means that the nerve impulses become slow and sluggish.

髓鞘后，冲动传导会变得迟缓。

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

髓鞘就像绝缘体，就像电线一样，帮助脉冲更快地传播。

Myelin speeds up nerve impulses, allowing actions associated with certain neurons to be performed with much less mental energy.

髓磷脂加快了冲动的速度，使得与某些元相关的动作可以用更少的精能量来完成。

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

轴突的某些位置可有髓鞘在外包绕。

Without myelin this signal propagation is very slow and inefficient.

如果没有髓鞘，信号传播会非常缓慢且低效。

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元细胞的结缔组织，可形成髓鞘，使成熟元的轴突绝缘。

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

轴突周围是髓鞘，实际上只是绝缘层。

Neural fibers are wrapped in a fatty substance called myelin.

纤维被一种称为髓磷脂的脂肪物质所包裹。

When you learn something, you have to thicken up your myelin and your neurons.

当你学习东西时，你需要增厚你的髓鞘和元。

So that specific, it's a myelin sheath, right?

所以那个特定的部分是髓鞘，对吧？

Alzheimer's has to do with the myelin in the human brain.

阿尔茨海默病与人类大脑中的髓鞘有关。

Myelin coats nerve cells and helps electrical signals travel.

髓鞘包裹着细胞，有助于电信号的传导。

And in the case of multiple sclerosis, it's destroying the myelin sheath.

在多发性硬化症的情况下，它正在破坏髓鞘。
