Basic Information
About Nail
Nail is a plate of Keratin that lies on
the tips of the fingers and toes. The
main purpose of the nail is to protect
the fingers and toes, however, the
fingernail also assists with certain
physical activities in daily life.
Fingernail Anatomy
Structure of Nail
1. Lunula
The pearly coloured and crescent
shaped is due to 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
hyponchium..
4. Matrix
The only living reproducing part of
the nail. This is situated directly
below the cuticle. New form
here and continually pushed
towards to produce the nail plate.
It also contains blodd 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 he ridges
on the undersurface of the nail
plate.
6. Nail walls
The folds of the skin that overlap
the sides of the nail. They
hold your nail in place and
protect the nail plate edges.
7. Nail Plate
Is visible nail that rest on the nail
bed up to the free edge. This
is made up from dead cells
and minimum amount of
moisture. This nail is semitransparent, allowing the
color of blood supply of the
dermis to show.
