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 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. 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。

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。
