一般每個手指和腳趾的端頭背面都有一個指甲，一共20個。雖然手腳指甲的構造大概相同，「指甲」一詞經常僅被用來指手指甲，而把腳趾甲稱為「趾甲」。健康人的指甲和趾甲一般呈現半透明突出的弧形，顏色略帶粉紅，表面大致光滑但帶有少量楞狀紋理。其平均生長速度為每天0.1毫米，具體的生長速度因個人年齡、新陳代謝速度、季節等因素而不同。A '''nail''' is a horn-like envelope covering the tips of the fingers and toes in most primates and a few other mammals. Nails are similar to claws in other animals. Fingernails and toenails are made of a tough protective protein called alpha-keratin. This protein is also found in the hooves and horns of different animals.
