Cov pas nrig ntawm cov hlwb txav mus rau ntawm daim tawv nqaij raws li cov cell tshiab tsim hauv qab lawv. Thaum lawv txav mus los, lawv raug txiav tawm ntawm lawv cov khoom noj thiab pib tsim cov protein ntau hu ua keratin. Cov txheej txheem no hu ua keratinization (ker-uh-tuh-nuh-ZAY-shun). Raws li qhov no tshwm sim, cov plaub hau tuag
