But where these cells join end-to-end you can see darker striations.

但是这些细胞首尾相连的地方你可以看到更暗的。

It's called smooth because, as you can see, unlike the other two, it lacks striation.

它被称为光滑的是因为，正如你所看到的，与其他两个不同，它没有。

It looks kind of clean and smooth, with obvious striations that resemble little pinstripes.

它看起来干净光滑，有明显的，似于小针。

And, we can see these striations where the muscles attach to the bone, itself.

而且，我们可以看到肌肉附骼上的这些。

Leaving us with an easy one — long, and straight cells with obvious striations AND multiple nuclei. This could only be skeletal muscle tissue.

剩下一个简单的——长而直的细胞，有明显的和多个细胞核。这可能只是骼肌组织。

These striations are caused by the arrangement of the protein molecules within the fibers that produce shortening or contraction of the fiber.

这些横是由纤维内使其收缩的蛋白质分子排列而形成的。

See if you can match the following tissue stains with their corresponding muscle tissue types. Don't forget to pay attention to striations and cell-shape!

看看你是否能将下面的组织染色与其对应的肌肉组织型相匹配。别忘了注意和细胞形状！

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——它们也是单核细胞，它们也紧密地挤一起。但是… … 没有。它们很光滑，所以这是平滑肌。

The lemon melon has the usual round shape of a melon, but its rind lacks the characteristic stripes and striation of a melon, and has white flesh.

柠檬瓜与其他瓜一样是圆形的，但其果皮没有典型的路，果肉是白色的。

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.

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

The lemon melon has the usual round shape of a melon, but its rind lacks the characteristic stripes and striations of a melon, and has white flesh.

柠檬西瓜和普通西瓜一样是圆形，但是外皮没有西瓜的标志性，果肉呈白色。

It is usually found as a sheath of muscle fibers surrounding a tube-like structure. When viewed from a microscope, there is no striation presented in the muscle, so it is called involuntary nonstriated muscle.

它通常作为围绕管样结构的肌纤维鞘而存。用显微镜观察时，肌肉上并不存横，所以它被称为非随意的无横肌。

Like skeletal muscle fibers, cardiac muscle cells have striations. Like smooth muscle fibers, each cardiac muscle cell has only one nucleus and its contraction and relaxation are not under conscious control. Therefore, it is also called involuntary striated muscle.

像骼肌纤维一样，心肌细胞也有。像平滑肌纤维一样，每个心肌细胞只有一个核而且其收缩和舒张不受意识控制。因此，它也被称为非随意横肌。
