Hello Steemit, the topic that I am going to talk to you about is the importance that we have to have ourselves with the care of our hands and nails.
They are a revealing cover letter that complement the image, the care of the nails do not escape treatments that will help them to have a hydration and a good nutrition. Each anomaly has a cause that is not always cosmetic but it can be the reflection of organic dysfunctions that end up showing the symptoms in the state and the color of the nails, if a nail does not grow it can be motivated by lack of vitamins and calcium that promote growth. Biting the nails also implies some anomalies in its growth, breakage fragility and even gets to modify the shape of the nail in its growth.
The hands: they are the first physical contact we have with people, beautiful and well-mannered hands say it all.
The nails are attached to the skin and in the same way that happens with the hair are the mirrors that reflect the good functioning and health of our body. A healthy nail has as main characteristic a smooth, shiny surface and a splendid pink and semitransparent color.
The nature of the nail is epidermal. Like hair, belongs to a group of protective tissues called faneras, essentially composed of keratin, hard material and very rich in protein and sulfur. The purpose of the nails is only to protect the ends of the fingers and toes. The nails grow in the folds that form on the tip and back of the fingers. Cuticles are nothing more than an extension of the skin that firmly holds one as it grows.
Structure of the nail
The nail is formed by the body, with a superficial surface where we see the lunula and a deep face in which the grooves or longitudinal channels can be seen, through which the one is anchored to the bed. The ends of the nail are formed by the root that remains hidden under the skin, in the base or moon of the nail, and the free edge that is the opposite end. The normal and healthy nail shows a structure in laminar stratification in the reticulum, nourished inside by glomeruli of tiny capillaries, which give it the splendid pink and healthy color that we all already know.
Matrix
It is part of the nail producing organ and is located in an area or visible and representative the root of the nail. The structure of the cells of the matrix changes in the lunula to transform into a nail matrix where the cells differentiate and it is the point where the nail grows.
Bed of the nail
It contains the grooves or longitudinal channels through which the deep face of the nail adheres very solidly and evenly to the nail bed. In adults, the ungular bed hardly participates in the production of nail plate production, but they also play a very important role in the nutrition of the nail plate. It is through the ungular bed where vascularization or blood supply arrives.
Lunar or half moon of the nail
It is the visible part of the matrix, since it protrudes forming a moon of color to the motifs that give that white color to the lunula, it is argued the increase of the mitotic activity of the cells (its rapid and abundant regeneration), may also be due to the increase of the keratin in which the light is reflected and gives that whitish color, while other scholars assure that it is due to the fact that being a younger part of the nail is shown with that white color.
Hyponychium (hyponychium)
It is the skin that forms on the fingertip and that remains completely hidden under the free edge of the nail. This skin is thicker and thicker as a result of the horny material produced Hyponychium that accumulates below the end of the nail. It constitutes a waterproof seal that protects the ungular bed from infections.
Eponychium
It has a particular form of sheet that covers the entire surface of the plate, thus contributing to the formation of the corneal layer. From the seventh month of gestation, this lamina becomes thinner and remains only as a corneal lamella that covers the region closest to the lunula. On the lower side it joins the dorsal layer of the nail plate.
Nail plate of the nail
It is the most important part because of the topic that concerns us with regard to the aesthetics of the nail. Above this plate or surface of the nail is where the specific treatments are carried out, both health, in terms of anomalies, as well as beauty treatments in terms of sculpted nail, where porcelain or fiberglass is modeled. also the surface that is worked with enamels and other specific cosmetic products. Its structure is formed with a corneous extract, made by numerous lamellae that are constructed by several layers of pink and semitransparent corneous cells, with a thickness that increases as the nail approaches the free edge of the nail. In adults, the nail is made up of three superimposed layers. A surface layer and a deeper one, both superimposed. A superficial layer and a deeper one, both of soft keratin and between which an intermediate layer of hard keratin is constituted. The main chemical component that makes up the nail plate of a healthy adult is keratin, a substance that generates the organism within the group of scleroproteins. At the same time it is formed by the following substances:
Amino Acids: are those that make up the group of lysines, methionine, cystine, thyroxine, tryptophan or phenylalanine.
Water: an important variation of the percentage of water that makes up a nail according to the season of the year has been proven, which is basically due to the diversity in the environmental humidity of the climate. also in people of advanced age the water content in the nail is decreasing, which explains the dehydration that the body suffers over the years.
