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，但与骨骼肌组织不同，它的胞通常是无核的，这意味着它有一个胞核。

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——它也是单核胞，它也紧密地挤在一起。但是… … 没有。它很光滑，所以这是平滑肌。
