Nail Structure & Growth
Transcript of Nail Structure & Growth
Why study Nail structure and growth?
Knowing helps us for grooming , strengthen and to beautify nails.
To tell the difference
thenail cuticle and the eponychium before services
understanding how the nail grows will help for more advanced nail services
The natural nail
also known as the onyx = is hard protective plate composed mainly keratin
The natural nail is located at the end of each finger or toe
It is an appendage of the skin and is part of the integumentary system, which is made up of the skin and its various organs
Natural nails cont.
A normal, healthy nail is firm but flexible.The surface is shiny, smooth and unspotted with no wavy ridges and pits or splits.
A healthy nail should be whitish , translucent with a pinkish color of the nail bed showing through
A healthy nail may look dry and hard but its water content is actually between 15 and 25 %
The water content directly effects the nails flexibility . The lower the water content the more the nail becomes ridged
The natural nail unit is composed of several major parts which include the nail plate, nail bed,matrix, nail cuticle,eponychium, hyponychium, ligaments and nail folds
The nail plate is a hardened keratin plate that sits on and covers the nail bed. Its the most visible and functional. Water can pass through the nail plate because it is porous.
is the portion of living skin that supports the nail plate as it grows toward the free edge.
The nail bed contains many nerves and is attached to the nail plate by a thin tissue called
Bed epithelium .
This helps guide the nail plate along the nail bed as it grows
Pinkish in color
is the area
where the nail plate cells are formed
, this area is composed of matrix cells that produce the nail plate cells
Is the visable part of the matrix that extends from underneath the living skin . Its the whitish half moon shape at the base of the nail
Everyone has a Lunula but
some are shorter than others and can be hidden under the eponychium
Nail Cuticle - Is the dead colorless tissue attached to the natural nail plate
Its job is to seal the space between the nail plate and living skin
is the living skin at the base of the natural nail plate that covers the matrix area
Is the slightly thickened layer of the skin that lies between the finger tip and the free edge of the natural nail plate.
is a tough band of fibrious tissue that connects bones or holds an organ in place. These ligaments are located at the base of the matrix and around the wedges of the nail bed .
are the folds of normal skin tht surrounds the nail plate. These folds form the nail grooves, which are the slits or furrows on the sidewalls.
Normal, healthy nails grow in a variety of shapes , depending of the shape of the matrix
The average rate of nail growth is about 1/10inch per month . Did you know that the thumb grows the slowest and the middle finger the fastest. It takes 9 months to 1 year to replace a toe nail .It takes 6 to 9 months to replace a finger nail .
Good luck on your test
