Question

what is the work of nail in our body ​

Answer 1

Explanation:

A healthy fingernail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries. It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger.

Answer 2

Nail

A nail is a claw-like keratinous plate at the tip of the fingers and toes in most primates. Nails correspond to claws found in other animals. Fingernails and toenails are made of a tough protective protein called alpha-keratin which is found in the hooves, hair, claws and horns of vertebrates.

Structure

The nail consists of the nail plate, the nail matrix and the nail bed below it, and the grooves surrounding it

Parts of the nail

Eponychium, Paronychium and Hyponychium are the major parts of the nail

Function

A healthy fingernail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries. It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger.[2] The nail then acts as a counter-force when the end of the finger touches an object, thereby enhancing the sensitivity of the fingertip,[14] although the nail itself has no nerve endings. Finally, the nail functions as a tool enabling a so-called "extended precision grip" (e.g. pulling out a splinter in one's finger), and certain cutting or scraping actions.
