But they are hundreds of pounds heavier than the other Aepyornis maximus specimens-and their bones look kinda different, too.

但是它们比其他马氏象鸟标本重数百磅——而且它们骨头看起来也有点不同。

For a long time, the biggest specimens had been classified as jumbo members of a species known as Aepyornis maximus.

在很长一段时间里，这个最象鸟标本被归为一种叫做马氏象鸟巨型成员。

But they are hundreds of pounds heavier than the other A. maximus specimens — and their bones look kinda different, too.

但是，它们比象鸟其它标本重数百磅，而且其骨看起来也有点不同。

Get ready to take it to the biggest muscle of the body, the gluteus maximus.

准备激活身体最肌肉——臀肌。

Designed to target the biggest muscle of the body, the gluteus maximus.

旨在针对人体最肌肉——臀肌。

But they are hundreds of pounds heavier than the other maximus specimens—and their bones look different, too.

但它们比其他巨型标本重数百磅——而且它们骨看起来也不一样。

The family joins swarms of people wading through hot ash on the cardo maximus and begins navigating towards one of Pompeii's southern gates.

一家人加入了一群人行列，他们在 cardo maximus 上涉过滚烫火山灰，开始驶向庞贝古城门之一。

So the gluteus maximus plays a very important role when you're— when you're running, and turns out to barely be active when you're walking.

因此，当你跑步时，臀肌起着非常重要作用，而当你走路时，臀肌几乎不活跃。

And so your gluteus maximus fires just before your body's about to—your trunk is about to pitch forward and make you hit your nose on the ground, and it helps pull your trunk backward.

因此，在你身体即将前倾并让你鼻子撞到地面之前，你臀肌就会启动，这有助于将你躯干向后拉。

And the other time the gluteus maximus fires is when your leg is swinging forward when you're in the air, and it helps decelerate the leg so that you bring your leg down onto the ground.

另一次，当你在空中时，当你腿向前摆动时，臀肌就会发火，这有助于使腿减速，以便你将腿落到地面上。

Each one of your different skeletal muscles — like your biceps brachii, or vastus lateralis or gluteus maximus — is technically its own organ, made up mostly of muscle tissue, but also of connective tissue, blood vessels, and nerve fibers.

你每一块不同骨肌——比如肱二头肌、股外侧肌或臀肌——严格来说都是自己器官，主要由肌肉组织组成，但也由结缔组织、血管和神经纤维组成。

And it turns out that very nicely we can see when the gluteus maximus got big in human evolution because its upper portion, the portion that's really important for this function, leaves a trace on the pelvis, on the bone.

事实证明，我们可以很好地看到臀肌在人类进化过程中何时变，因为它上部，即对该功能非常重要部分，在骨盆和骨上留下了痕迹。

For centuries Popes have been given the honorary title “pontifex maximus”, which literally translates as “the greatest bridge builder.”

几个世纪以来，教皇被授予“祭司长”荣誉称号，这个词字面意思可译为“最伟桥梁建造者”。
