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，但肌组织不同，它们的胞通常是无核的，这它们只有一个胞核。

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——它们也是单核胞，它们也紧密地挤在一起。但是… … 没有条纹。它们很光滑，所以这是平滑肌。
