聽我說

Matrix is the area where nail growth originates.

基質是指甲生長的起源區域。

It lies below the skin.

它位於皮膚下方。

Matrix has specialized cells which keep dividing and creating nail cells.

基質中的特化細胞會不斷分裂並生成指甲細胞。

The nail cells grow and produce a hard protein called keratin.

指甲細胞生長併產生一種叫做角蛋白的硬蛋白。

Then, these keratin filled cells are pushed forward as more new cells are formed behind them.

然後，這些充滿角蛋白的細胞會被推向前方，因為在它們後面會形成更多的新細胞。

Eventually, the keratin filled cells die and flatten to form the nail plate.

最終，充滿角蛋白的細胞死亡並變平，形成甲板。

The hard keratin in these dead cells gives strength to the nail and makes it hard.

這些壞死細胞中的硬角蛋白賦予指甲力量，使其堅硬。
