Structurally speaking, you've got fibrous, cartilaginous, and synovial joints.

从结构上来说，你有纤维关节、软关节和滑膜关节。

As for cartilaginous fish, Conseil went on unflappably, they consist of only three orders.

至于软鱼类，康塞尔很冷静地又说，那就只有三目。

Their cartilaginous skeletons are less dense than bony ones and require less energy to move.

这些生理特质从4亿多年中进化而来它们软质比硬更轻。

Within the chameleon's mouth, a tongue muscle squeezes a series of concentric sheaths around a cartilaginous rod, storing elastic energy.

在变色龙口腔中，舌肌紧缩软棒周围舌鞘，储存弹性能量。

Yes, of course. So which type of joint can you crack? Is it … a) fibrous? b) cartilaginous? Or c) synovial?

当然。那么你能掰响哪一种关节？是a)纤维性关节? b)软性关节? c)滑液性关节?

These are distant, cartilaginous cousins of sharks that live in the deep sea today.

这些是今天生活在深中鲨鱼远亲软表亲。

In their wake, bony fish and cartilaginous fish like sharks and rays took over the oceans.

在它们身后，硬鱼和软鱼如鲨鱼和鳐鱼接管了。

Spoken like a true glutton, Conseil replied. But tell me, are you familiar with the differences between bony fish and cartilaginous fish?

这是讲究吃喝人一种分类法，康塞尔回答，请您告诉我，您知道硬鱼类和软鱼类之间存在差别吗?

Several of these classes are specific types of fish, for example: jawless fish, like lampreys and hagfish, and cartilaginous fish, like sharks and rays.

这些纲类一些便是鱼类，比如：无颚纲鱼形动物，像七鳃鳗、盲鳗和软纲鱼，像鲨鱼和魔鬼鱼。

If we look at the really successful features of sharks you've got to consider this cartilaginous skeleton – that's no bone in the skeleton.

如果我们研究鲨鱼真正成功特征，你必须要考虑到软——那是指中没有头。

The canal is divided into two parts: (a) cartilaginous and (b) bony (a) Cartilaginous Part It forms outer one-third (8 mm) of the canal.

耳道由两部分组成：软部分和质部分。（a）软部分它组成了管道外部三分之一（8 毫米）。

We should remember that the skull at this early age is cartilaginous and flexible, so that it readily yields to muscular action.

我们应该记住， 这么小头是软和柔韧， 因此它很容易屈服于肌肉活动。

Because their skeletons were cartilaginous, what remains of megalodons are mostly scattered clues, like some isolated vertebrae and lots of their enamel-protected teeth.

因为巨齿鲨骼是软质，所以留下大部分都是零散线索，比如一些孤立椎和许多受牙釉质保护牙齿。

Once contracted, they compress the arms of the cartilaginous skeleton at the base of the salamander's tongue, which then launches out with the rest of its tongue tissues.

一旦收缩，它们就会压缩蝾螈舌头底部软骼，然后连同舌头其他组织一起发射出来。

There's a magnificently well preserved dinosaur from Italy, which includes the cartilaginous tracheal rings, still preserved in the throat, and muscle fibers at the base of the tail.

有一种来自意大利保存完好恐龙，它包括仍然保存在喉咙中软气管环和尾巴底部肌肉纤维。

As you might guess, your cartilaginous joints unite bones using cartilage, and are similar to their fibrous brethren in that they don't move very much, and they lack a joint cavity.

正如你可能猜到，你软关节用软连接头，和它们纤维兄弟相似，它们不怎么移动，也没有关节腔。

OK, if you say so, Professor. And since you're in a scientific mood, how about answering today's quiz question. Which type of joint can you crack? Is it … a) fibrous? b) cartilaginous? Or c) synovial?

好吧，随你怎么说吧，大教授。既然你想谈论科学，那么就来回答一下今天测试题吧。人体哪一个关节可以被掰响？是a)纤维性关节? b)软性关节? c)滑液性关节?
