Cardiac muscle tissue is also striped, or striated, but unlike skeletal muscle tissue, their cells are generally uninucleate, meaning that they have just one nucleus.

心脏肌肉组织也有条纹，但与骨骼肌组织不同，它们的细胞通常是无核的，这意味着它们只有一个细胞核。

Skeletal muscle is also termed voluntary striated muscles. The name " striated" comes from the characteristic cross striations of the muscle fibers when viewed under a microscope.

骨骼肌也称为随意横纹肌。当在显微镜下观察时，肌纤维上可见特征性横纹，" 横纹肌" 的名称就来源于此。

The cells are striated. Each cell only has one nucleus. But the giveaway here is probably the cells' branching structure; where their offshoots meet with other nearby cells where they form those intercalated discs. It's cardiac muscle.

这些细胞是条纹状的，每个细胞只有一个细胞核。但这里的信息可能是细胞的分支结构，它们的分支与附近的其他细胞相遇，形成了那些夹层盘。这是心肌。

Your heart is so important that it gets its very own muscle tissue type — cardiac muscle, which looks striped, or striated, and also functions involuntarily to keep your blood pumping without you having to think about it.

你的心脏是如此重要以至于它有自己的肌肉组织类型——心肌，看起来是条纹状的，它也不由自主地起作用来保持你的血液流动，而你不用去想它。
