The amnio results should put your mind at ease.

羊膜穿刺术结果应该可以令你放心了。

In more serious cases, amniocentesis, where a sample is taken directly from the amniotic sac surrounding the fetus, can be performed.

在严重情况下，需行羊膜穿刺术，即直接从胎儿周围羊膜囊穿刺取样检查。

Now, there are different types of amniotic eggs.

现在，有不同类型羊膜蛋。

Amniotic fluid, the protective liquid surrounding the fetus within the amniotic sac.

羊水，即羊膜囊内环绕胎儿保护。

So I got the results of the amnio today.

羊膜刺穿术结果今天出来了。

Amniotes with one temporal fenestrae are called synapsids.

具有一个颞孔羊膜动称为突触。

And amniotes with two temporal fenestrae are called diapsids.

具有两个颞孔羊膜动被称为双孔动。

But on an increasingly dry planet, that gave amniotes a critical advantage.

但在一个越来越干燥星上，这给了羊膜动一个关键优势。

Their amnio caused these birth defects.

他们羊膜刺穿术导致胎儿先天缺陷。

As the Permian progressed, amniote predators like Dimetrodon, Ophiacodon, and eventually saber-toothed gorgonopsians became widespread.

随着二叠纪推进，像二齿兽、蛇齿兽和最终剑齿戈尔贡OPS这样羊膜动捕食者变得广泛分布。

By the time this catastrophe occurred, most lineages of temnospondyls had already gone extinct, under pressure from the amniotes.

到这场灾难发生时，大多数扁平头类分支已经在羊膜动压力下灭绝了。

Since reptiles, mammals, and birds are all amniotes, amniote eggs must have existed in their last common ancestor, the first true amniote.

由于爬行动、哺乳动和鸟类都是羊膜动，羊膜卵一定存在于它们最后共同祖先，即第一个真正羊膜动中。

It's just kind of part of the normal fluid that surrounds the body in the, in the amniotic sac and stuff like that.

它只是包围身正常一部分，在羊膜囊之类东西中。

Some of our earliest fossil records of amniote eggs are from dinosaurs like Mussaurus patagonicus, which lived around 215 million years in Argentina.

我们最早一些羊膜卵化石记录来自恐龙， 例如巴塔哥尼鼠龙，它们在阿根廷生活了大约 2.15 亿年。

Aquatic temnospondyls managed to hang on for tens of millions of years by sticking to watery habitats and avoiding the amniotes on land.

水生扁平头类通过坚守水域栖息并避免与陆上羊膜动接触，成功存活了几千万年。

And that balloon bag is surrounded by thick muscle, which is the uterus, surrounds the entire bag and has, actually, a thicker portion at the bottom.

而那个像气一样羊膜囊被厚厚肌肉层包围，这就是子宫， 它包裹着整个羊膜囊，并且在底部有一个更厚部分。

Unlike the temnospondyls, these early amniotes were free to reproduce far from the water, by laying eggs with protective shells, which were probably more leathery than mineralized.

与扁平头类不同， 这些早期羊膜动可以在远离水源方繁殖，它们产下蛋有保护壳，这些壳可能更像皮革而不是矿化质。
