Okay, let's look at the muscle cells.

好，我们来看一下肌肉细胞。

This is because calcium is getting into your muscle cells.

这是因为钙进入了你的体内 肌肉细胞。

This means that these muscle cells become less reactive to stimuli.

这意味着这些肌细胞对刺激的反应性降低。

Robots one day might even be made of living muscle cells.

有朝一日我们可以用活肌细胞制造机器人。

Starting from muscle cells, we can already print, grow and stimulate muscles.

我们从肌细胞开始，已经具备了打印、培养、刺激肌肉的能力。

This forms the bulk of the heart tissue, because those cardiac muscle cells contract and pump blood.

他们构成了大部分心脏组织，这是因为心肌细胞能收缩，从而实现泵血。

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

在我们的肌肉细胞中，肌动蛋白结构形成了这些看起来像布料的规则纤维。

Those antibodies also activate the complement pathway which leads to muscle cell destruction.

这些抗体也会激活补体通路，破坏肌肉细胞。

All three types are made up of muscle cells, also known as fibers, bundled tightly together.

这三种肌肉都由肌肉细胞构成，以纤维的形式，紧紧地贴合在一起。

Those found in adults are more limited: turning into blood cells, say, or muscle cells.

只能变成血液细胞或肌肉细胞。

This messenger's job is to tell muscle cells to contract.

这种化学信使的作用则是让肌肉细胞进行收缩。

Now, a new study in mice shows how a hormone secreted by active muscle cells triggers bone remodeling.

现在，一项在老鼠身上进行的新研究揭示了活跃肌肉细胞分泌的激素是如何触发骨骼重塑的。

They saw that the fungus had invaded and grown into jaw muscle cells, perhaps to suck up nutrients.

他们发现，真菌已经侵入并在颚肌细胞中成长，可能是为了吸收营养。

Caffeine also causes the release of calcium inside of muscle cells, and it can prevent or slow its reuptake.

咖啡因还会导致肌肉细胞内钙的释放，并阻止或减缓钙的重新摄取。

They had poor endurance, their muscles were 60% weaker than normal mice, and their muscle cells had fewer mitochondria.

它们没什么耐力，肌肉群比普通老鼠弱了60%，且肌肉细胞内线粒体含量更少。

These fish have evolved electric organs at least 100 million years ago by converting muscle cells to electro sites.

这些鱼至少在1亿年前将肌肉细胞转化为电子细胞, 进化出了电子器官。

In the end, people who take steroids can have three to five times more nuclei in some muscle cells.

最终，在服用类固醇的人的肌肉细胞中，某些细胞的细胞核可能比一般人多三到五倍。

Okay, so as a quick recap: the protein dystrophin is super important for stabilizing the muscle cell membrane.

抗肌萎缩蛋白对肌纤维稳定性的维持极其重要。

This messenger's job is to tell muscle cells to contract. Without that signal, muscles stops working.

这种化学信使的作用则是让肌肉细胞进行收缩。没有这种信号的话，肌肉便停止工作了。

The nitric oxide diffuses into the nearby smooth muscle cells, and activates guanylate cyclase, which converts GTP molecules to cGMP.

一氧化氮扩散到附近的平滑肌细胞，激活鸟苷酸环化酶，将GTP分子转化为cGMP。
