-the standard [human fingernail] is [1 CM] wide-
-a nail is a ‘horn-like envelope’ covering the ‘tips’ of the [‘fingers’ / ‘toes’] in most ‘primates’ and a few other ‘mammals’-
(‘nails’ are similar to ‘claws’ in other animals)
(‘fingernails’ + ‘toenails’ are made of a tough protective protein called ‘keratin’)
(this protein is also found in the ‘hooves’ + ‘horns’ of different ‘animals’)
-the [top white part] of the ‘finger-nail’ is the ‘free edge’-
