Question

What is the purpose of 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 on the surface 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.
