This is a tutorial on the muscles of the face.

So the muscle is responsible for facial expression.

So these muscles are innervated by the seventh cranial nerve, the facial nerve.

這些肌肉由第七顱神經--面神經支配。

So when you're testing a patient's cranial nerves, and you get to cranial nerve.

是以，當你測試病人的顱神經時，你會發現顱神經。

Number seven, you ask them to wrinkle their forehead to close their eyes as tightly as they can as they can to show you their teeth by making a smile and um asking them to puff their cheeks out.

第七項，你要求他們皺起額頭，儘可能緊閉雙眼，做出微笑的樣子給你看他們的牙齒，嗯，要求他們鼓起臉頰。

So this is a crude test of the muscles of facial expression.

是以，這只是對面部表情肌肉的粗略測試。

So the way I'm going to do do this tutorial is that I'm gonna start superiorly and work through the the various muscle groups in the face.

是以，我在本教程中的做法是，從上部開始，練習面部的各種肌肉群。

So the um orbital muscle group, the nasal muscle group and then the muscles in the oral region.

即眼眶肌群、鼻腔肌群和口腔區域的肌肉。

So to begin with, um looking at the most superior muscle on the face, we you can see this muscle here, which is the frontal belly of the occipitofrontalis muscle.

首先，我們來看看面部最上方的肌肉，你可以看到這塊肌肉，它是枕額肌的額腹。

Um and it's called the occipitofrontalis muscle because it consists of two muscle bellies.

它被稱為枕額肌，因為它由兩塊肌腹組成。

So you've got the occipital muscle belly, so called because it's on the occipital region of the um skull.

枕骨肌腹之所以叫枕骨肌腹，是因為它位於頭骨的枕骨部位。

And you've got the frontal belly of the oyo frontalis and connecting these two muscle bellies.

還有額肌的額腹，連接這兩塊肌腹。

You've got this flat tendon sheath, this aponeurosis.

你有這個扁平的腱鞘，這個肌腱膜。

Um And if you, if you have covered the layers of the scalp, um you'll have been told that the aponeurosis of the o ccy frontalis makes up the third layer of the scalp.

如果你已經瞭解了頭皮的各層結構，那麼你就會知道額肌肌腱構成了頭皮的第三層。

So you've got skin connective tissue, aponeurosis, loose connective tissue and then the periosteum.

是以，你有皮膚結締組織、肌腱、疏鬆結締組織和骨膜。

So the upper neurosis of the occ sept frontalis, um it's the third layer of the scalp.

額隔膜的上神經節是頭皮的第三層。

So if we just look at the orbital region, um we can see these muscles which surround the eye.

是以，如果我們只看眼眶區域，就能看到這些環繞眼球的肌肉。

Um and this muscle is called the orbicularis oculi.

And it's a, it's acts sort of as a sphincter of the eye.

And you've got an outer part um add an inner part to this muscle.

你有一個外側部分，嗯，在這個肌肉上加一個內側部分。

So this outer part here is called the orbital part and it's responsible for closing the eyelids forcefully.

外側的這部分叫做眼眶部分，負責用力閉合眼瞼。

If I just zoom in a little bit more, you can see that in a part of the orbicular circulate.

如果我再放大一點，你就能看到球狀循環的一部分。

And this is called the palpable part and it resides inside the eyelid and it's responsible for closing the eyelid gently.

這部分被稱為 "可觸及部分"，位於眼瞼內部，負責輕輕閉合眼瞼。

So that's the Abili oculi, this circular muscle responsible for closing the closing the eyelids.

這就是眼輪匝肌，負責閉合眼瞼的環形肌肉。

So the next muscle is this muscle here, the corrugator super silly and it lies just um deep to the oculis ole and it draws the eyebrows immediately and downward.

下一塊肌肉就是這裡的這塊肌肉--皺眉肌（corrugator super silly），它位於眼輪匝肌的深處，能立即將眉毛向下拉。

There are three muscles associated with the um nasal muscles of the face and the nasal group.

有三塊肌肉與面部的 um 鼻肌和鼻群有關。

Um So you've got the procerus, you've got the nasalis which consists of a transverse part and an um aar part.

是以，你有前鼻翼，你有鼻孔，鼻孔由橫向部分和弧形部分組成。

And you've got this muscle in the midline, which is called the depressor septa nasa.

在中線上有一塊肌肉，叫做 "下壓隔肌"。

So, the procerus muscle here on either side, originates on the nasal bone and inserts onto the skin of the forehead.

是以，兩側的前額肌起源於鼻骨，插入前額皮膚。

And this muscle is active when an individual frowns.

當一個人皺眉時，這塊肌肉就會活躍起來。

And these muscles here, the na the nasal, sorry, the nasalis, which consists of the transverse part and the alar part is responsible for compressing and um flaring the nostrils, the nares.

這些肌肉包括鼻橫肌和鼻翼肌，負責壓迫和擴張鼻孔。

So the transverse part compresses the nostrils and the alar part, um they are part of the nasalis.

是以，橫向部分會壓迫鼻孔和鼻翼部分，嗯，它們是鼻翼的一部分。

Um flares helps to flare the nostrils, it opens them up.

Um flares 有助於擴張鼻孔，讓鼻孔張開。

Um And this muscle here that depresses sept NASA.

還有這塊肌肉，它能壓迫宇航局。

So the name kind of gives away what it does.

Um So it actually inserts onto the nasal septum.

所以它實際上是插入鼻中隔的。

Um and it assists the A r part of the nasalis in widening the nostrils.

它還能協助鼻翼的 A r 部分擴大鼻孔。

So those are the three muscles of the nasal group of the facial muscles, the procerus, the trans uh the nasalis and the depressor nasa septic.

這就是面部肌肉鼻組的三塊肌肉：前鼻肌、橫呃鼻肌和下鼻肌。

So, the next group of muscles is the or group of muscles.

是以，下一組肌肉是 或 肌肉。

Um And as you can see, there's quite a lot of muscles which make up this group.

正如你所看到的，這組肌肉由很多塊肌肉組成。

So if you're not interested in learning about all those in detail, then I'll just cover the two muscles that you need to know and you can switch off after that.

是以，如果你對詳細瞭解所有這些不感興趣，那麼我將只介紹你需要知道的兩塊肌肉，之後你就可以關掉了。

And then if you're interested, you can carry on listening uh to find out about the other muscles.

如果你感興趣，還可以繼續收聽，瞭解其他肌肉的情況。

So what you need to know in the oral group, um If you are going to learn two muscles is that there's this big muscle here which forms a circle around the mouth.

如果你要學習兩塊肌肉，那麼在口腔組你需要知道的是，這裡有一塊大肌肉，它在口腔周圍形成一個圓圈。

Um And this is known as the UBI Iis Iris.

So just like you've got the circular muscles around the eyes, which constrict around the eyes, the Ubi oculi, you've got the UBI Iris.

是以，就像眼睛周圍的環形肌肉一樣，眼球周圍的環形肌肉會收縮，這就是 UBI 虹膜。

So in Latin Oculus is an eye and Os oris is um a mouth.

是以，在拉丁語中，Oculus 是眼睛，Os oris 是嘴巴。

So orifice oris help you to remember that.

是以，"孔口 "可以幫助你記住這一點。

So BIIS iis this circular mouth, circular muscle which um circles the mouth.

是以，BIIS 就是這個環形口腔，環形肌肉環繞著口腔。

Um and you can kind of guess what the function is when it contracts, it narrows the mouth and closes the lips.

嗯，當它收縮時，你可以猜到它的功能是什麼，它能使嘴巴變窄，嘴脣閉合。

 So you get this pursing action um which you get when you're whistling and that's brought about by this muscle, the orbicularis oris. 

是以，當你吹口哨時，就會出現 "嗚咽 "的動作，而這是由眼輪匝肌帶來的。
