Narrator: 我认为指甲是手指的重要组成部分，但人们往往忽视它们。指甲由死组织构成，没有神经，但能增强手指的触觉敏感性，并能反映身体内部的健康状况。同时，咬指甲是一种常见的习惯，虽然通常无害，但也有传播细菌和损伤指甲的风险。 Phalanx: 我是Phalanx，以指骨命名。我向大家介绍了指甲生长的关键——甲母质，它是产生角蛋白细胞的地方。我还强调了某些食物对指甲健康的重要性，比如红肉富含蛋白质和铁，水果可以保护指甲免受损伤。 Lunula: 我是Lunula，我的名字来源于甲母质的一部分。我解释了男性指甲比女性生长速度快，并阐述了指甲与爪子的区别。指甲使我们更容易使用工具和进行精细动作。
