💅 Nails: Protection for Fingers and Toes
Learn about nail anatomy, how nails grow, and tips for keeping your child's nails healthy
What Are Nails?
Nails are plates of hardened protein packed into layers. They support and protect the sensitive tips of our fingers and toes. We use our nails for many tasks, like picking up small objects, scratching an itch, and untying a knot. Nails are made of keratin, the same tough protein found in hair and the outer layer of skin.
💅 Key Functions of Nails
- •Protection: Shield sensitive fingertips and toes from injury
- •Grip: Help pick up small objects and improve dexterity
- •Scratching: Provide a tool for relieving itches and removing debris
- •Support: Strengthen fingertips for fine motor tasks
What Are the Different Parts of Nails?
Nails have many parts that work together to create strong, protective coverings for fingertips and toes.
🔧 Nail Matrix
The area at the base of the nail that makes new cells
This is where nail growth begins and continues throughout life
🌙 Lunula
The white part of the matrix that looks like a crescent moon
Visible at the base of the nail, especially on thumbs
💅 Nail Plate
The largest part of the nail that you can see
Looks pink from the network of tiny blood vessels beneath it
🛏️ Nail Bed
The skin underneath the nail plate
Contains blood vessels that give nails their pink color
🔄 Nail Folds
Areas of skin around the nail plate that hold it in place
Provide structural support and protection
🛡️ Cuticle
Thin layer of skin that comes from the nail fold near the lunula
Attaches to the nail plate and protects the matrix from infection
How Do Nails Grow?
Cells grow in the matrix at the base of the nail. As new cells are made, they move up to the surface of the skin and push the older cells up and forward toward the tip of a finger or toe. The cells get pressed tightly together to make a thin plate. Plates pile into layers to form the nail. During this process the cells become hard and die. This hardening is called keratinization.
🌱 Growth Process
- • New cells form in the matrix
- • Cells move up and forward
- • Cells harden through keratinization
- • Plates stack into layers
⏱️ Growth Rates
- • Fingernails: ~3mm per month
- • Toenails: ~1mm per month
- • Faster in summer than winter
- • Faster in children than adults
🔄 Regeneration
- • Nails can grow back after injury
- • Matrix must not be severely damaged
- • Complete regrowth takes months
- • Toenails take longer than fingernails
How to Keep Your Child's Nails Healthy
✂️ Proper Trimming
- • Trim nails straight across, not too short
- • Use clean, sharp nail clippers
- • File rough edges gently
- • Don't cut cuticles
🧼 Hygiene
- • Keep nails clean and dry
- • Wash hands regularly
- • Avoid biting nails
- • Use moisturizer to prevent cracking
Frequently Asked Questions
❓ Why do nails grow faster in summer?
Increased blood circulation and exposure to sunlight can accelerate nail growth during warmer months.
❓ What causes white spots on nails?
White spots are usually caused by minor injuries to the nail matrix and are harmless. They grow out with the nail.
❓ Can nails grow back if completely removed?
Yes, nails can grow back if the matrix (growth center) is not severely damaged. Complete regrowth takes several months.
