它存在于我们的腔、舌头和许多腺体中。

Now the mucosal tissue in the oral cavity can undergo several premalignant pathological changes.

The oral microbiota plays an important role in maintaining oral homeostasis protecting the oral cavity and preventing disease.

The oral cavity and oropharynx are lined by epithelium - and there are a few different types.

腔和上皮覆盖，有几种不同类型的上皮。

These microbes play an important role in maintaining oral homeostasis, protecting the oral cavity, and preventing disease development.

这些微物在维持腔内动态平衡、保护腔预防疾病等方面起到了重要作用。

The major genera with the largest representation in the oral cavities include: streptococcus, prevotella, haemophilus, rothia, veillonella, neisseria, fusobacterium, and porphyromonas.

腔中的微物主要包括以下几个大属：链球菌属、普氏菌属、嗜血杆菌属、罗氏菌属、韦荣氏球菌属、奈瑟氏菌属、梭杆菌属卟啉单胞菌属。

The pizza goes in our oral cavity where we use our teeth to masticate, or chew the food up into small fragments.

披萨进入腔后，我们用牙齿咀嚼食物，将食物嚼成小块。

Most of the oral cavity is lined by stratified squamous epithelium, so the majority of cancers that arise are squamous cell cancers.

腔内大部分表面都由复层鳞状上皮覆盖，所以大部分腔癌都属于鳞状细胞癌。

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腔侧切面的图形来表示。

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

腔：腔是产大部分语音的地方。

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腔和内，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.

嘴唇形成的开，而脸颊或颊形成腔的边界。

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

腔内的结构包括牙齿，舌头和腭，它们对食物的咀嚼（粉碎）和吞（下）起作用。

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

腔：腔位于腔后面， 是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.

得！快速回顾一下：腔癌指起源于腔的癌症；腔由角化或未角化的复层鳞状上皮覆盖。

The oral cavity. The process of digestion begins in the mouth, also called the buccal cavity, which is the opening through which food enters the body.

腔。消化过程是从开始的，也可以说是从腔开始，腔是食物进入体内的开。

The soft palate can be lowered to block the oral cavity and allow air to pass through the nasal cavity so that a NASAL sound is produced.

腔内部的器官对发音至关重要。从前面开始，腔的上部包括上唇、上齿、齿龈、硬腭、软腭和小舌。软腭可以下垂使气流通过鼻腔，如果同时在腔中发阻塞，发出的就是鼻音。

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.

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

Oropharyngeal cancers are strongly associated with infection by human papillomavirus type 16, but interestingly, tumors of the oral cavity, like the lateral tongue and floor of the mouth are not usually associated with HPV 16.

癌人乳头瘤病毒（HPV）16型的感染密切相关，但有趣的是，在腔肿瘤中，像是舌两侧和底的肿瘤则一般HPV 16没有联系。

Alright, as a quick recap, the human oral microbiota is represented by the community of microorganisms which are normally found in the oral cavity and can exist as free-floating bacteria, or in the form of a biofilm.

得！快速回顾一下～人类腔微物群以腔内常见微物群为代表；这些微物群可以是游离的细菌，也可以以物膜的形式存在。
