Unlike our skeletons, actin filaments are constantly being built and taken apart.

和我们骨架不同，肌纤维（微丝） 一直在不停被组装和拆散。

The actin cytoskeleton plays incredibly important roles in our cells.

肌骨架在我们细胞中扮演着至关重要角色。

They've got their own famous coupling — a pretty pair of tiny protein strands called actin and myosin.

它们有自己著名联结——一对漂亮微小质链，叫做肌和肌球。

Actin is also involved in a different kind of movement.

肌还和另一种不同运有关。

Specifically, that club-headed myosin wants to get all up-close-and-personal with the actin.

具体来说，棒状头肌球想近距离接触肌。

In our muscle cells, actin structures form these regular filaments that look kind of like fabric.

在我们肌肉细胞中，肌结构形成了这些看起来像布料规则纤维。

This movement is powered by one of my favorite proteins called actin, which is part of what's known as the cytoskeleton.

它由我最喜欢之一，肌驱，这种是所谓 “细胞骨架”一部分。

Like the actin and myosin in our muscles that enable us to move.

就像我们肌肉中肌和肌球一样，它们使我们能够移。

Actin and myosin, the proteins of muscles, permit those bodies to move around.

肌和肌球， 肌肉质， 允许这些身体四处移。

And jidaga are really indispensable in the cell.

而且肌在细胞中真不可或缺。

Are there specific movements and exercises that you would recommend?

当我们把骨骼肌视为一个器官系统时， 必须理解在锻炼或运时， 骨骼肌会执行某些功能。 我们为何关注运？ 我们关注运， 是因为当我们收缩骨骼肌时， 为器官系统骨骼肌会分泌肌。 肌是一种小， 它们在全身各处游走。

That's these little actin skeletal projections on the mobile edge of the cell that definition.

这就是细胞移边缘上这些小肌骨骼突起定义。

Is it because of the mykines floating through their system and such?

这是否是因为他们体内循环肌等物质在起用呢？

They have critical roles in organizing the actin skeleton.

它们在组织肌骨架中起着关键用。

They produce compounds that act like cat pheromones. Silver vine, for example, produces a cat pheromone-like molecule called actinidine.

它们产生类似于猫信息素化合物。例如，银藤会产生一种类似于猫科物信息素分子，称为肌。

Open rings did even worse – that extra cut made figuring out actomyosin alignment even trickier.

开口环效果更差——那个额外切口使得确定肌-肌球纤维排列更加困难。

Myokines are little proteins that travel throughout the body.

肌是遍布全身小质。

Hydra have thin, parallel actomyosin fibers running throughout their body, like our muscle tissue.

水螅体内分布着细长且平行肌-肌球纤维，类似于我们肌肉组织。

But you can't just breathe in the stuff you need to build DNA, or actin, or a phospholipid bilayer.

但是你无法仅仅靠呼吸来构建脱氧核糖核酸、肌或磷脂双分子层所需东西。

Namely, actin is blocked by a couple of protein bodyguards — called tropomyosin and troponin — which keep getting in the way.

也就是说，肌会被质保镖阻断——原肌球和肌钙——它们一直碍事。
