what is the main function of the fingernail
Function of the Fingernail. The fingernail is an important structure made of keratin. The fingernail generally serves two purposes: it acts as a protective plate and enhances sensation of the fingertip. Nails can also help grasp small things. The protection function of the fingernail is commonly known, but the sensation function is equally important. The fingertip has many nerve endings in it that allow it to receive volumes of information about the objects we touch.
