Let's not forget that humerus bone on the upper arm.

让我们不要忘记上的肱骨。

This is your humerus, all right?

这是的肱骨，好吗？

It corresponds exactly to the location and function of the humerus in our arms.

它我们手中肱骨的位置和功能完全对应。

So no, you can't break your funny bone but it can hurt a lot.

所以不，无法让的肱骨内髁部骨折，但它会很疼。

It's where your upper arm bone, the humerus, meets the two bones of your forearm.

它是连接上骨，即肱骨，的两根骨头的交汇处。

Its humerus and femur were shorter, and its lower limb bones were longer, more like the legs of other ungulates.

它的肱骨和股骨较短， 下肢骨骼较长，更像其他有蹄类动物的腿。

They also needed new limb supports — a more robust humerus to support the arm, and a pelvic girdle to support the legs.

他们还需要新的肢体支撑——更结实的肱骨来支撑手，骨盆带来支撑腿。

In elephants and sauropods, as those animals got larger throughout their evolution, their humerus and femur grew longer, while the other bones in their forelimbs, hindlimbs, and feet became shorter, more compressed, or even fused together.

在大象和蜥脚类动物中，随着这些动物在整个进化过程中变大，它们的肱骨和股骨变长，而前肢、后肢和脚中的其他骨骼变得更短、更压缩，甚至融合在一起。
