What is the primary function of nails?

The primary function of nails is to protect the fingertips and enhance dexterity. Nails serve as a barrier that safeguards the sensitive areas of the fingers and toes, helping to prevent injury and damage from external forces. Additionally, they contribute to our ability to perform precise tasks, such as gripping and manipulating small objects, which are essential for everyday activities. The combination of protection and enhanced dexterity highlights the functional significance of nails beyond aesthetic considerations.

While providing a surface for nail art is a popular use of nails, it does not constitute their primary biological function. Similarly, nails do not play a role in moisture absorption or body temperature regulation, which are functions managed by other parts of the body. Understanding the essential role of nails helps emphasize their importance in both protection and functionality in daily life.
