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。

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

裂 2 的四个主步骤是：前 2、中 2、后 2 和末 2。

It's metaphase. You want to check it?

是中 你看看吗？

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同源染色体对沿着中起移动：成对的同源染色体沿着将纺锤体为二的赤道平面排列。

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裂中停止裂，并且在卵泡向黄体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细胞，并触发它最终再次开始裂——让它完成裂 I 并进入中 II。
