祝你和 "吱吱 "玩得開心，"小杰西"！

Squeaks is finally going on his trip around the world tomorrow!

吱吱明天終於要去環球旅行了！

And while I've been helping him pack, we've been talking about our senses and the body parts we use to gather information from the world around us.

在我幫他收拾行李的時候，我們一直在討論我們的感官以及我們用來從周圍世界收集資訊的身體部位。

While I can't go with him, we've come up with ways that I can experience what he senses during his trip.

雖然我不能和他一起去，但我們想出了一些辦法，讓我能在他的旅行中體驗他的感受。

He's going to use this camera to take pictures to show me what he saw with his eyes, and record audio of the sounds that he used his ears to hear.

他要用這臺相機拍照，向我展示他用眼睛看到的東西，並用耳朵錄下他聽到的聲音。

How else could you share your experiences?

Well, we need to figure out things to do that can take the place of your senses.

好吧，我們得想辦法做些事情來代替你的感官。

We need you to settle another argument for us.

我們需要你為我們解決另一場爭論。

Yes, after Bill told you about how birds hear, we decided to learn more about all the senses we have.

是的，在比爾告訴你鳥類的聽覺之後，我們決定進一步瞭解我們所有的感官。

I say there are five senses—sight, hearing, touch, taste, and smell.

我說有五種感官--視覺、聽覺、觸覺、味覺和嗅覺。

You know, the one you never seem to have when it's time to go someplace warmer in the winter?

你知道，當冬天要去一個更暖和的地方時，你似乎從來沒有帶過的那個？

Sometimes you'll hear people say we have the five senses Bill just mentioned.

有時你會聽到人們說，我們有比爾剛才提到的五種感官。

But there really are more senses than that!

First, sensory organs like our eyes have special parts called receptors.

首先，像眼睛這樣的感覺器官有一個特殊的部分，叫做感受器。

A receptor captures a specific kind of information from the outside world, then changes it into a signal that goes to the brain.

感受器捕捉外界的特定資訊，然後將其轉化為信號傳入大腦。

And once the signal gets to the brain, the brain directs the body what to do to respond.

一旦信號傳到大腦，大腦就會指揮身體做出反應。

When we talked about the eye, we talked about photoreceptors and how we see.

當我們談到眼睛時，我們談到了感光器和我們是如何看到東西的。

Photoreceptors take in light, then change the light into a signal.

感光器接收光線，然後將光線轉變為信號。

The brain makes sense of that signal, so we know what we're looking at.

大腦會對信號進行理解，是以我們知道自己在看什麼。

And when we talked about the ear, we covered the receptors called hair cells in the inner ear that change sound waves into signals that our brains use for our sense of hearing.

當我們談到耳朵時，我們介紹了內耳中被稱為毛細胞的感受器，它能將聲波轉化為信號，供我們的大腦用來產生聽覺。

We also have receptors in our tongue, nose, and skin for our senses of taste, smell, and touch.

我們的舌頭、鼻子和皮膚上也有味覺、嗅覺和觸覺感受器。

Some of the receptors in our skin, like the ones that help us feel if something is soft or bumpy or hard, sense pressure.

我們皮膚上的一些感受器，如幫助我們感受物體是否柔軟、凹凸或堅硬的感受器，可以感知壓力。

And different receptors in the skin help us to sense temperature.

皮膚上的不同受體幫助我們感知溫度。

When we wash our hands before we eat, these receptors sense how warm the water is.

當我們在吃飯前洗手時，這些感受器會感知水的溫度。

But if the water gets too hot, a completely different kind of receptor senses that we might hurt our skin.

但是，如果水溫過高，一種完全不同的感受器就會感覺到我們的皮膚可能會受傷。

These are pain receptors, and they can cause the body to take action fast.

這些是痛覺感受器，它們能讓身體迅速採取行動。

So we pull our hands out from under the hot water quickly, and the skin doesn't get damaged.

是以，我們要迅速將手從熱水中抽出，皮膚才不會受損。

I don't like what those receptors make me feel at all!

我一點也不喜歡這些感受器給我帶來的感覺！

But pain receptors are super important because they let us know when something's not right with our bodies, so we can figure out what's going on and hopefully fix it if we need to.

但痛覺感受器是超級重要的，因為當我們的身體出現問題時，它們會讓我們知道，這樣我們就能找出問題所在，並在必要時進行修復。

Well, for example, we have receptors that give us a sense of balance.

例如，我們的感受器能讓我們產生平衡感。

If you could see deep inside your ears, you'd see a part that's made of three loops full of liquid.

如果你能看到耳朵深處，你會看到一個由三個充滿液體的環組成的部分。

And inside these loops, there are little receptors that can send signals up to the brain that tell it which way your head is facing.

在這些迴路中，有一些小受體可以向大腦發送信號，告訴大腦你的頭朝向哪個方向。

This is how we know which way is up, down, left, and right.

這就是我們如何知道上、下、左、右的方向。

Without this sense, we couldn't stand or sit upright.

沒有這種感覺，我們就無法站立或坐直。

I never thought about that before, but that's an important sense!

我以前從沒想過這一點，但這是一個重要的意義！

There's also a really cool one called proprioception.

還有一種很酷的方法叫本體感覺。

Way more fun to say than sight or hearing, but what's it mean?

說起來比視覺或聽覺有趣得多，但它是什麼意思呢？

Proprioception is the sense of where our body is in space.

先天知覺是對身體在空間中所處位置的感知。

Close your eyes and think about where the tips of your wings are.

閉上眼睛，想想你的翅膀尖在哪裡。

或者你的手指，如果你有的話。

Even though you couldn't see anything, while you were moving your body, you knew where everything was.

儘管你看不見任何東西，但當你移動身體時，你知道一切都在哪裡。

Where are the receptors for proprioception?

Well, they're found in places like your muscles and joints.

它們存在於肌肉和關節等部位。

This sense of body awareness also helps us figure out how much force we need to use when doing different activities.

這種對身體的感知還能幫助我們瞭解在進行不同活動時需要使用多大的力量。

Like, picking up an empty water bottle is going to require a little less oomph than a full one.

比如，拿起一個空水瓶所需的力氣要比拿起一個滿水瓶小一些。

Speaking of water, what about feeling thirsty?

Nah, that's just part of the sense of taste!

Remember, to be a sense, there have to be receptors.

請記住，要有感覺，就必須有感受器。

Our tongues have receptors in them that sense different flavors, like salty or sweet.

我們的舌頭上有感受器，可以感知不同的味道，如鹹味或甜味。

Instead, we feel thirsty when our brain detects the amount of water throughout our body is getting too low.

相反，當我們的大腦檢測到全身的含水量過低時，我們就會感到口渴。

Okay, but what about my sense of the passage of time?

好吧，那我對時間流逝的感覺呢？

You want Tiny Jesse to experience balance and proprioception for me?

你想讓小杰西為我體驗平衡和本體感覺？

What else are you going to do on your trip, Squeaks?

你在旅途中還打算做什麼，吱吱？

Dancing requires both balance and muscle movement.

Although, remember, Tiny Jesse doesn't have receptors.

不過，請記住，小杰西沒有受體。
