TOOTH在英语中的意思是什么？

齿

Tooth

牙齿是许多脊椎动物的颌骨中发现的一种小而钙化的白色结构，用于分解食物。 一些动物，特别是食肉动物，也可以使用牙齿进行狩猎或防御目的。 牙根被牙龈覆盖。 牙齿不是由骨制成，而是由不同密度和硬度的多个组织制成。 最终成为牙齿的细胞组织起源于胚胎胚层（外胚层）。 尽管脊椎动物的形状和位置有相当大的变化，但脊椎动物的牙齿的一般结构是相似的。 哺乳动物的牙齿有深根，这种模式也发现在一些鱼类和鳄鱼。 然而，在大多数硬骨鱼中，牙齿附着在骨的外表面上，而在蜥蜴中，它们通过一侧附着在颌骨的内表面上。 在软骨鱼如鲨鱼中，牙齿通过坚韧的韧带连接到形成颌骨的软骨箍上。 牙齿是哺乳动物物种最显着的特征之一。 古生物学家使用牙齿来识别化石物种并确定它们的关系。 动物牙齿的形状与其饮食有关。

A tooth is a small, calcified, whitish structure found in the jaws of many vertebrates and used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness. The cellular tissues that ultimately become teeth originate from the embryonic germ layer, the ectoderm. The general structure of teeth is similar across the vertebrates, although there is considerable variation in their form and position. The teeth of mammals have deep roots, and this pattern is also found in some fish, and in crocodilians. In most teleost fish, however, the teeth are attached to the outer surface of the bone, while in lizards they are attached to the inner surface of the jaw by one side. In cartilaginous fish, such as sharks, the teeth are attached by tough ligaments to the hoops of cartilage that form the jaw. Teeth are among the most distinctive features of mammal species. Paleontologists use teeth to identify fossil species and determine their relationships. The shape of the animal's teeth are related to its diet.

在英语 词典里tooth的定义

字典中牙齿的第一个定义是在大多数脊椎动物的颚骨中设置的各种类似骨骼的结构，并根据物种进行修改，用于咬，撕裂或咀嚼相关的形容词牙齿。 牙齿的其他定义是无脊椎动物中任何类似的结构，发生在口腔或消化道。 牙齿也是形状，突出或功能上类似牙齿的东西。
