STRUCTURES OF NAIL
1. Lunula - the pearly colored and crescent shaped is due
to the cells being pushed closely together, the blood
capillaries cannot be seen through the lunula because of
this.
2. Cuticle - the overlapping epidermis around the nail. It
is the transparent skin, which is called the 'true cuticle',
that is removed during the manicuring process
3. Free edge -the part of the nail that can be filed and shaped.
It is an extension of the nail plate that overlaps the
hyponychium.
4. Matrix - the only living reproducing part of the nail. This is
situated directly below the cuticle. New cells form here and
continually push towards to produce the nail plate. It also
contains blood vessels and nerves. Blood supply provides the
cells with nourishment. If the matrix is damaged the nail will
grow deformed.
5. Nail bed - the part of the nail where the nail plate
rests on, also a continuation of the matrix. It is
abundantly supplied with blood vessels and nerves,
having numerous parallel ridges which dovetail exactly
with the ridges on the under surface of the nail plate.
6. Nail walls - the folds of skin that overlap the sides of
the nail. They hold your nail in place and protect the
nail plate edges.
SHAPES OF NAIL
The shape of nail conforms to that of finger
tips of an individual.
STILETTO
1. Oval nail - this is common among
people with long, perfect nail beds. It
may be styled slightly rounded at the
base and slightly pointed at the
fingertips. Most often this type of nail has
a natural look and looks very good in a
short-medium length.
2. Round nail - ideal for shorter nails, the
nail is allowed to grow out straight at the
sides for approximately 1.5 mm and then
the tip is filed into a rounded shape. This
is a strong shape which is great for those
who keep their nails short.
3. Stiletto/ pointed nail - filed away at
the sides to a point at the tip; this shape is
very weak as the sides of the nail (which
provide the strength) are totally lost
STILETTO
4. Squoval - as above, but followed by
squaring off the tip, this gives the nail tip
strength over the oval shape
5. Square nail- the square-shaped nails
are the most famous among the nail
shapes. It is created by allowing the nail
to grow out straight and then filing the
tip straight across at right angles with the
rest of the nail plate.
