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

次级卵泡会在第二次减数分裂中停止分裂，并且在卵泡向黄换的时候等待受精。

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，并触发它最终再次开始分裂——让它完成减数分裂 I 并进入中 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 2、中 2、后 2 和末 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， 当我们拍摄染色的照片时，这将是我们的染色的照片，它们通处于中。

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

中 1同源染色对沿着中板一起移动：成对的同源染色沿着将纺锤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 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（中板）上。

It's metaphase. You want to check it?

是中 你要看看吗？
