Can nails be associated with a part of a person s body?

Nails are a barometer of human health, normal nails are ruddy, tough and curved, smooth and shiny, and the nail half moon at the base of the nail is grayish-white. If the color of the nail shape changes, it indicates that the human body may be suffering from some kind of disease. Here's some common sense about nails:

Judging by the shape of the nails: the nails are flattened, sunken, spoon-shaped, brittle and dull, and there are signs of insufficient liver water or iron deficiency anemia, hypochromic anemia and light-colored microcytic anemia. The nails are parrot-shaped, and the fingertips are like drumsticks, which are more common in congenital heart disease with cyanosis, rheumatic heart disease, chronic heart failure and lung abscess, emphysema, silicosis, chronic fibrous cavitary tuberculosis, chronic ulcerative colitis and other diseases.

Striated fingernails are a precursor to kidney disease or myocardial infarction; The appearance of longitudinal streaks is a precursor to liver disease; The presence of inverted pits is a sign of poor respiratory function.

Judging from the color of the nails: the nails turn white, and the emergency is seen in blood loss and shock; Chronic symptoms are seen in anemia, hookworm disease, gastrointestinal bleeding, advanced tuberculosis, cor pulmonale, etc.; If it is as white as ground glass, it is characteristic of cirrhosis; Whitening, thinning and softening of the nails is more common in chronic wasting disease. Yellowing of the nails is a lack of vitamin E, which is seen in hypothyroidism, carotenemia, nephrotic syndrome, etc.

When the nails turn gray, you have onychomycosis. The purple nail surface with small red thorns is caused by hypoxia and indicates heart and lung disease. Nails that are half red and half white are not functioning well.

White spots or flocculent white spots on the nails may be zinc deficiency or gastrointestinal disease or anemia; The presence of dark or indispensed spots is a sign of poisoning; Erythema around the nails is more common in patients with lupus erythematosus and **inflammation. The nail and half moons are blue and have poor peripheral circulation; Significant redness is a sign of heart failure; If the first half moon is obvious, the intestinal absorption is good; Those who have no or are small have poor digestion.

Nails are indeed a window to observe human health, so we should always pay attention to its changes, especially for long-term nail artists, and forget to give nails a vacation every once in a while, so that it can show its true face, and if multiple nail variations are found, you should see a doctor in time.

Directly from the nails, you can see the liver function poorly, and the reaction to the function of the message system.

The nail is a flattened nail-like structure on the back of the finger (toe) of humans and apes, which belongs to connective tissue. It is a deformation of the claw, also known as the flat claw, and its main component is keratin. Homologous to the claw, the claw plantar retracts, and the claw plate forms a rectangular sheet, which is the product of epidermal keratinization at the end of the finger (toe) and plays a role in protecting the end of the finger (toe).

Species of the suborder Primate apes and primates have nails. Some species of the suborder Protomonkey do not have nails, and some species only have fingernails at the ends of some fingers, such as bee monkeys (slow loris) with claws on the second toe and nails on the rest, while finger monkeys only have nails on the first finger (toe) and the rest of the fingers (toes) are claws.

Nails are derived from **. Like **, it is formed by the gradual differentiation of the mesenchyme of the embryonic body surface, ectoderm and lateral plate wall layer and somite raw dermal segment after 9 weeks of embryonic life. The nail is divided into the nail plate, nail bed, nail fold, nail groove, nail root, nail epithelium, and subungual skin.

The deck is equivalent to the **chemical layer, and the nail fold is the part that bends into the nail groove. The nail bed consists of an accessory layer equivalent to the epidermis, a basal layer, and a dermal reticular layer. The lower part is directly fused with the periosteum of the phalanges.

The posterior nail fold covers the nail root and migrates to the nail epithelium. The anterior nail bed is the subungual skin. The nail fold does not participate in the growth of the nail plate, which is caused by the proliferation and keratinization of methyl cells at the root of the nail and the migration forward across the nail bed.

But the nail bed controls the growth of the nail in a certain shape. If the nail bed is damaged, the nail will grow out of shape. The nail bed and nail root are rich in blood vessels.

These provide a wealth of nutrients for nail regrowth.

Patients need to adjust their body and mind in a way that is needed for a healthy life.

Nails are like small imaging devices, and many diseases in the human body can be reflected from the nails. The nails of healthy people are smooth, smooth, translucent, uniform reddish in color, and have a certain curvature attached to the finger ends. At its root, there is a half-moon-shaped white nail arc, which plays a protective role in the nails, commonly known as "health circles", and the changes in the shape, luster and color of the nails can reflect the health of the body.

Vertical streaks on the nails: It may be kidney failure, pancreatitis, long-term inflammation of the small intestine, rheumatism, nutritional disorders, or vitamin A deficiency.

Horizontal lines on the nails: Most are caused by a lack of nutrients, but they can also occur after surgery and heart attacks. In addition, horizontal striped nails are often an important indicator of intestinal infections and pneumonia.

Some people also have this symptom after having measles or fever, but before the onset of myocardial infarction.

Nails with cotton-like white clouds and white spots: it could be a problem with the intestines.

Soft and weak nails: a sign of malnutrition.

Nails are flat, pitted, spoon-shaped, dull, and brittle, and are iron deficiency anemia.

Nail bulge: The transverse and longitudinal ridges of the nail are highly curved and raised, and many diseases can make the nail bulge, such as chronic lung disease, congenital heart disease, thyroid disease, liver cirrhosis, ulcerative colitis and certain malignant tumors.

Spoon-shaped nails: the nails are thin, ** sunken, and the edges are upturned like spoons, which are commonly found in hypohemochromatic anemia, long-term iron deficiency or hyperthyroidism, hyperadrenal gland function, rheumatic fever, hookworm disease, syphilis and other diseases.

Round nails: Anyone with heart disease, lung disease, chronic lack of oxygen, liver atrophy, or kidney failure is likely to have round nails.

Inverted triangle shape of the nail indicates a predisposition to stroke and paralytic disease.

Cracked nails: People who regularly touch detergents with their fingers are prone to cracked nails, and in addition, they may have thyroid dysfunction, circulatory disorders, or have a severe** disease.

Nails are blue and purple: usually caused by hypoxia, if it is systemic, it is mostly caused by arterial blood hypoxia caused by congenital heart disease, chronic lung disease, heart failure and other diseases.

White nails: If the nails are all white, pale is cold, and pale is anemia.

Blue nails: People with acute abdomen have cold limbs and sudden blue nails. Stillborn women will continue to turn blue when fingered. In addition, bruising of the nails may indicate poisoning or early cancer.

Green nails: Partial or total green color of the nails, if not caused by long-term exposure to detergent or soap, may be caused by infection with Pseudomonas aeruginosa.

Gray nails: more common in malnutrition, rheumatoid arthritis, hemiplegia, or myxedema.

Mainly keratin, but also trace elements such as calcium.

The nail body (nail cap) is generally known as a nail, which is composed of 3-4 layers of hard, scaly cuticle overlapped, and does not contain capillaries and nerves. The nail cap is located between the nail root and the anterior edge of the nail and is attached to the nail bed by keratin fibers.

nail bed; It is the best tissue that supports the nail body, is closely connected with the nail body, supplies the nail body with moisture, the nail bed contains a large number of capillaries, the nail body is pink, and the color of the nail bed has a lot to do with the health of the person.

Nail root; Located at the root of the nail, in front of the methyl group, it is extremely thin and soft, and its effect is similar to that of the rhizome of a crop. The nail root continuously pushes the newly produced nail keratin cells to grow forward and promote the metabolism of the nail.

methyl group (i.e., methyl mother); Located at the base of the nail, it contains capillaries, lymphatic vessels, and nerves, and acts like soil. Methyl groups are the basis for nail growth after absorbing nutrients from the human body and producing keratinocytes that make up nails.

Human nails are keratin on the tips of the fingertips, which have the effect of protecting the fingertips. Nails are made up of proteins, keratin and sulfur, and they grow millimeters in a week.

The function of the nail is mainly to protect the nerve-rich fingertips from injury. Protein, keratin and sulfur are the main building blocks of nails, which are about millimeters long each week. Abnormal changes in the nails are associated with a deficiency of various cantyloids.

Dry and cracky nails: Lack of vitamin A and calcium. Processing:

Strengthens nails with a special nail moisturizing oil. Groove scarring: Vitamin B deficiency.

Treatment: You can use a nourishing oil that repairs grooves. The nails are blackened and the ends are rounded:

Lack of vitamin B12. Long spines: lack of protein, folic acid, vitamin C.

Treatment: Use soft leather scissors to cut off the meat spines. and apply a soft skin oil.

White streaks appear: lack of protein. Grow mold:

People who do not have enough benign bacteria (lactobacilli) in their bodies and have short nails have weak hearts, and are prone to diseases from the abdomen to the waist and lower body. If the tip of the nail is flat and embedded in the flesh, it may be susceptible to neuralgia, rheumatism and other diseases.

People with narrow lower nails, ridges and other bones are susceptible to diseases, especially those with very soft nails, and calcium is always very deficient.

People with shell nails should pay more attention to minor problems in the spinal cord and nervous system.

Too many white spots on the nails are a symptom of neurasthenia, and there are yellow dots that indicate a digestive disease. Small particles on the nails are a sign of drug poisoning or parasites in the body.

If the half-moon shape at the lower end of the nail is large, it indicates rapid blood circulation. If it is small, the blood circulation is not good, and when it comes to extreme anemia, the half-moon shape will disappear completely.

Straight lines on the nails are evidence of overwork and overuse of the brain.

At the beginning of a dangerous pathology, the horizontal line is only exposed at the lowest end of the nail and gradually moves upwards as the nail grows, and those who are skilled in this way can infer the possible period of the disease from the position of the horizontal line.

1. The nail color of healthy people is pink. If you put ten nails in the sun and move your fingers up and down, if there is a shiny reflection on the surface of the nails, it shows that the overall health is in excellent condition, and the organs in the body are functioning properly.

2. Brown longitudinal lines or longitudinal cracks appear on the surface of the nail, extending from the fingertips to the root of the nail, which indicates intestinal inflammatory lesions or indicates vitamin deficiency and iron deficiency. Partial whitish nails indicate zinc deficiency. Plain whitish is indicative of anemia.

Brownish-yellow streaks on the nails are a sign of liver disease. However, it is worth noting that this brownish-yellow stripe must appear on ten fingernails at the same time, which is liver disease; Presence alone is not diagnostic evidence.

3. If there are many thimble-like pits on the nails, it is most likely a late symptom of psoriasis.

4. Swelling on the fingers and purple halo on the nails is likely to be a lung disease. Nails become thinner, brittle, or even cracked, indicating diseases of the respiratory and circulatory systems.

5. The middle of the nail is inverted, like a spoon-shaped, indicating that you have diabetes, anemia, hyperthyroidism or malnutrition.

6. There are dark reddish-purple blood spots under the nails, which often indicate purpura and blood diseases.

Left over from the process of human evolution, it plays a role in protecting the hands and toes, and it is also a prevention.

If you cut your nails to the shortest possible length and do as much work as you can, you'll know how important your nails are to protect your fingers at the end of the day.
