The vowels are shown their relevant positions in a cross-sectional diagram of the oral cavity.

在国际音标表中，语音音段分为辅音和元音两类，将在下节详细讨论。辅音又分为肺气流音和非肺气流音：多数辅音是肺气流音，通过从肺部排出气流来完成；非肺气流音包括挤喉音、内爆音和吸气音，吸气音是将空气向口腔内吸入进行发音，内爆音和挤喉音都是紧闭声门，通过对声门和声道前部某一发音部位之间空气的控制进行发音。元音的相对位置通过一个口腔侧切面的图形来表示。

Because the volume of your airways and oral cavity and sinuses is probably much different than mine.

Oral cavity: The oral cavity is where the majority of speech sounds are produced.

Many carcinogens come into contact with a wide area within the oral cavity and oropharynx, so the idea is that they cause field cancerization.

许多致癌物可以广泛接触到口腔和口咽内，故有一个猜想就是这些物质引发区域癌化。

The lips form the opening to the mouth, while the cheeks or bucca (buccae) form the borders of the oral cavity.

嘴唇形成口的开口，而脸颊或颊形成口腔的边界。

The structures within the oral cavity including the teeth, tongue, and palate, are involved in the chewing (mastication) and swallowing (deglutition) of food.

Pharyngeal cavity: The pharyngeal cavity is located behind the oral cavity and serves as a transition point between the oral and nasal cavities.

咽腔：咽腔位于口腔后面， 是口腔和鼻腔之间的过渡点。

All right, as a quick recap, oral cancer refers to cancers that originate in the oral cavity, which is lined by keratinized or non-keratinized stratified squamous epithelia.

While the prognosis of squamous cell carcinoma in the oral cavity depends largely on the tumor stage, HPV status is a main prognostic factor for squamous cell carcinoma in the oropharynx.

口腔鳞状细胞癌的预后，很大程度取决于肿瘤分期，而感染HPV的状况则是口咽部鳞状细胞癌的一个主要预后因素。
