Question

What is the purpose of forming ridges and grooves on the skin of our fingers?

• A. To provide sensation.
• B. To help regulate temperature.
• C. To protect from UV rays.
• D. To provide efficient grip.

Answer 1

The correct option is D To provide efficient grip.

Fingerprints (and footprints) are tiny ridges in the surface part of the skin (epidermis) that are formed by lines in the deep skin (dermis). They probably give us better grip by giving our skin more friction. They may also help keep the skin from tearing easily.
