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.

心脏肌肉有条纹，但与骨骼肌不同，它们的胞通常是无核的，这意味着它们只有胞核。

Or these — they're uninucleate cells, too, and they also are packed together pretty closely together. But… no striations. They're smooth, so this is smooth muscle.

或者这些——它们是单核胞，它们紧密地挤在起。但是… … 没有条纹。它们很光滑，所以这是平滑肌。
