The problems included a decrease in the production of myelin.

包括髓磷脂产量的下降。

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

如果神经被髓鞘覆盖，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。

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神经纤维，就会更具有传导作用，髓磷脂所富含的脂肪也更多一些。

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

髓鞘质是施万细胞产生的；施万细胞是支持神经的神经胶质细胞。

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

失去髓鞘后，神经冲动传导会变得迟缓。

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

髓磷脂加快了神经冲动的速度，使得与某些神经元相关的动作可以用更少的精神能量来完成。

Typically, individuals slowly recover over several months as there's regrowth of the myelin on peripheral nerves.

通常，随着周围神经髓鞘的再生，患者会在几个月后缓慢恢复。

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

髓鞘由支持神经元的少突胶质细胞形成。
