The physical properties and function of nails

  • A. Y. Finlay


Nails are not only an evolutionary hangover from our ancestors’ jungle-life. We continue to make use of our nails as weapons, as tools, for body care and as social ornaments. The functions of nails, however, depend on their physical properties which in turn are directly dependent on their gross anatomical structure, their cellular structure and hence on their biochemical components.
