Nails serve several important functions in the human body, including:

1. Protection: Nails protect the tips of our fingers and toes from injury and trauma. They act as a barrier to prevent damage to the sensitive tissues underneath.

2. Grip and manipulation: Nails provide a rough surface that helps us grip and manipulate objects with our fingers. This is especially important for tasks that require fine motor skills, such as picking up small objects or typing on a keyboard.

3. Sensation: Nails contain nerve endings that help us sense touch and pressure. This allows us to feel and respond to our environment, such as feeling pain when we accidentally hit our finger with a hammer.

4. Support: Nails provide structural support to the tips of our fingers and toes, helping to maintain their shape and strength.

5. Beauty and self-expression: Nails can be used as a form of self-expression through nail art and manicures. They are also considered a symbol of beauty and grooming in many cultures.
