WHAT IS A NAIL?

The nail is a flexible plate of horny tissue, fabricated up of keratin, i.e. epidermic cells formed in the root of the boom and hardened.

The Matrix

The Matrix is the living portion establish at the base of operations of the boom. This is where new cells develop and push the erstwhile, "dead" cells forrad to form the nail plate. The quality and health of these cells determine the general condition of the nail every bit it grows beyond the matrix.
The matrix is supplied by numerous blood vessels and nerves which provide the nourishment necessary for the product and growth of nail tissue.
This is the most sensitive part of the whole nail construction and can hands exist damaged through mistreatment. Any blow or abuse can impede normal growth and crusade discolouration and ridges or other irregularities to appear on the nail plate. These eventually grow out unless serious injury has resulted in permanent damage to the smash.
Everything that happens to the human body tin impact nails, in item the aftereffects of childbirth or illnesses such as high fever, pneumonia, etc. can be translated by furrows that form on the lunula and gradually grow out with the blast. Even psychological shocks tin can affect the matrix and appear on the surface of the nail as uneven or deep grooves.

The Nail Bed

The boom bed is the continuation of the matrix. Acting equally a support bed for the nail plate, it plays a vital role in the health, colour and texture of the boom. The nail plate is joined to the nail bed by a serial of minute connecting ridges that run from the matrix to just brusk of the fingertip, where the nail detaches to course a free edge.

The Lunula or One-half Moon

The lunula or half moon, that whitish crescent at the base of the nail, is the simply visible portion of the matrix. Information technology is not always prominent, although information technology commonly is visible on the thumbnail, diminishing in size until the little finger, where it is usually non visible.

The Nail Plate

The boom plate is the visible role of the smash from lunula to free border. It is composed of compressed skeleton cells produced in the matrix and contains no blood or nerves. Normally pale pinkish in colour, information technology may get white or bluish depending on temperature and other concrete weather. Although the nail plate seems to be i single piece, information technology is really three layers separated by minute amounts of wet and fat. These layers vary in consistency, the external layer existence the hardest and the inner layer, which adheres to the blast bed, the softest.

The Nail Tip or Free Edge

The nail tip or gratis border is the free part of the nail bed and protrudes across the end of the finger. How far is a affair of taste. This is the most vulnerable part of the blast and tin hands be damaged past touch, incorrect filing, etc.

The Cuticle

The cuticle is the rim of skin framing the nail plate that protects the hardening blast. The cuticle is constantly discarding old cells and producing new ones. Unless this tissue remains soft and pliable, it can abound onto the surface of the nail where it becomes unsightly, splits into hangnails and can even impede nail growth.

HOW DOES THE NAIL Grow?

The nail originates in the matrix as part of the epidermis, or outer layer of the pare. It hardens and thickens through a process called keratinization, becoming less firmly attached to the nail bed, which explains the white of the lunula. Equally growth continues, the nail becomes thinner and once again fixes itself firmly to the nail bed, taking on a pink tone.
Depending on private growth charge per unit, it takes from 3 to 5 months for a boom to grow completely.
Nails generally grow faster and stronger in summer than winter, and grow faster on the right hand of correct-handed person, the left hand of a left-handed person. The growth rate may be too more rapid during pregnancy.

Healthy Nails and Balanced Nutrition.

"You are what you eat" is a popular saying, and certainly one'southward fingernails reflect i's diet. Dietary deficiencies not only forestall nails from growing normally, but as well tin can cause weakness and brittleness, ii of the near exasperating issues.
Vitamins, calcium and minerals are peculiarly of import to the growth and maintenance of potent, healthy nails.
A vegetarian diet tin can weaken the nails every bit it produces imbalance due to the lack of animal proteins. Similarly, a poorly counterbalanced weight-reduction diet is not beneficial to the wellness of the nails.

What aresome causes ofdamagednails?

Just as poor health and dietary deficiencies can inhibit the growth of a blast, so can illness and diet influence the condition of otherwise sound nails. Resulting damage can be of short-term duration and requires immediate attention. Internal causes should be referred to a qualified dr. or dermatologist for treatment

Internal causes

In full general, whatever circulatory condition that reduces the supply of blood to the matrix of the boom prevents it from receiving proper nourishment and developing normally. Other wellness problems that can affect the nails include glandular disorders, poor metabolism, allergies, anemia, deficiencies of calcium, certain amino acids and other essential nutrients.

External causes

A healthy nail can be damaged in many ways, including the following :

direct contact with solvents, strong detergents and other cleaning products,
over-exposure to sunlight or dry atmospheric conditions,
heavy pressure or potent blow against a hard object,
application of nail shine directly to the blast plate, without protection of preliminary base coat.
