The secondary oocyte stops in metaphase of meiosis 2, and waits for fertilization as the menstrual cycle transitions into the luteal phase.

卵泡会在第二减数分裂中期停止分裂，并且在卵泡期向黄体期转换的时候等待受精。

The LH gets to work on the oocyte that's been dormant inside the follicle, and triggers it to finally start dividing again — getting it to complete meiosis I and move on to metaphase II.

LH 开始作用于卵泡内休眠的卵母胞，并触发它最终再开始分裂——让它完成减数分裂 I 并进入中期 II。

The four main steps of meiosis 2 are: prophase 2, metaphase 2, anaphase 2, and telophase 2.

减数分裂 2 的四个主要步骤是：前期 2、中期 2、后期 2 和末期 2。

Now the reason it characteristically looks like an X is that when we take a picture of our chromosomes, this would be a picture of our chromosomes, they're usually in metaphase.

现在它看起来像 X 的原因是， 当我们拍摄染色体的照片时，这将是我们的染色体的照片，它们通常处于中期。

Metaphase 1 Homologous pairs move together along the metaphase plate: the paired homologous chromosomes align along an equatorial plane that bisects the spindle.

中期 1同源染色体对沿着中期板一起移动：成对的同源染色体沿着将纺锤体一分为二的赤道平面排列。

In metaphase 2, the centromeres contain two kinetochores that attach to spindle fibers from the centrosomes at opposite poles.

中期 2，着丝粒与纺锤丝连结。

It's going to line up along the metaphase plate.

它将会排列在 metaphase plate（中期板）上。

It's metaphase. You want to check it?

是中期 你要看看吗？
