Structure Fits Function

Functions for Nails:

• Protection
• Attack

 

Structure:

• Making smaller movements more precise
• It makes the finger tip more sensitive
• Protecting the finger tips

 

Have you ever wondered about what makes up you nail? The structure of the nail is very simple.

If you look at your finger nail, you will see that part of the nail covers your nail bed and part of your nail that sticks out.  

The part of the nail that sticks out (the white part of your nail)  is called the free edge of the nail.  The part of the nail that is covering your nail bed is called the body of the nail.

These are some of the functions of the nail:

 

• The free edge of the nail makes smaller movements more precise. For example, if you were picking up a needle, the free edge of the nail would be useful.
• The body of the nail is helpful because it protects the sensitive finger tips.  It also allows the fingertips to be more sensitive.
• The lunula is actually under your nail, if something/someone hurts the lunula, your nail will be deformed.
