Why do we need nails?
Nails serve several functions. They help protect the delicate tips of fingers and toes from injury. They exert a counterpressure on the fingertip , which can help with precise movements and touch sensitivity. Finally, nails provide a valuable tool for cutting, scraping, or pinching very fine objects.
What is the structure of fingernails?
Nail Structure and Function. Fingernails and toenails are derived from the stratum corneum. They serve a protective function and can be used as tools. The stratum corneum, or horny layer, of the epidermis gives rise to fingernails and toenails. Like this outer layer, nails are composed primarily of the tough protein keratin.
What is the nail bed?
Like skin elsewhere in the body, the nail bed is skin with a layer of epidermis and a layer of dermis. The epidermis of the nail bed is attached to the nail plate via grooves called matrix crests. This epidermis of the nail bed moves toward the end of the nail as the nail grows.
What is the nail plate?
The nail plate is the actual fingernail that is composed of dead cells. The nail bed is below the nail plate and has both dermis and epidermis tissue. The nail matrix, sometimes called the matrix unguis, is the part of the nail bed that sits at the base of the nail plate. < Hair Structure and Function > Skin Glands.
What are the parts of the nail?
Nails have three main parts: the nail plate, the nail bed, and the nail matrix. The nail plate is the hard part of the nail, composed of layers of dead cells. The nail bed sits beneath the nail plate. Like skin elsewhere in the body, the nail bed is skin with a layer of epidermis and a layer of dermis. The epidermis of the nail bed is attached ...
What is the cuticle of a nail called?
This is called the lunula, or small moon . The cuticle is a protective layer of dead cells that cover and seal the back of the nail plate. Finally, the hyponychium, or quick of the nail, sits between the open edge of the nail and the fingertip and protects the nail bed. Nails serve several functions.
What is the crescent at the base of a nail called?
A small portion of the nail matrix is visible as a white crescent at the base of some nails. This is called the lunula, or small moon.
What are Fingernails Made of?
Fingernails are a plate or piece of hardened keratin found at the ends of fingers. Keratin is a protein that forms skin, hair, and nails. Fingernails grow continuously from the second trimester of pregnancy for a fetus till a few minutes after death. Their growth rate varies throughout life based on age, nutrition, and illness.
Parts of a Fingernail
While fingernails appear to be a simple structure, as with many things in the body, they are more complex than they first appear. Understanding each part and function helps to appreciate this body part.
Function of Nails
All primates have fingernails, including humans, monkeys, and apes. Human fingernails are typically wider when compared proportionally to other primates. Nails have many different functions. These include:
What is the function of the nail?
They enhance the sensation. The fingers and toes contain nerve endings that allow the body to process the volumes of information that it receives every time something is touched—and the nail acts as a counterforce, providing even more sensory input after a person touches something.
Why are nails important?
They help humans function. Nails are basically flat versions of claws that help humans dig, climb, scratch, grab, and more. They guard against injuries. They serve as protective plates that help prevent the fingers and toes from getting cut or scraped during daily activities. They enhance the sensation.
What is the site of hangnails, ingrown nails, and paronychia?
The paronychium is the site of hangnails, ingrown nails, and paronychia, a skin infection. Hyponychium: The hyponychium is the area between the free edge of the nail plate and the skin of the fingertip. It also provides a waterproof barrier.
What happens if your nail doesn't grow?
When the nail grows properly, the nail bed is smooth, but if the nail doesn't grow correctly, the nail may split or develop ridges that aren't cosmetically attractive. Nail plate: The nail plate is the actual fingernail, and it's made of translucent keratin.
How fast do fingernails grow?
Fingernails grow faster than toenails, at a rate of 3 millimeters per month. It takes six months for a fingernail to grow from the root to the free edge. Toenails grow much more slowly, at just 1 millimeter per month.
Why do nails look pink?
The pinkish appearance of the nail comes from the blood vessels that are underneath it . The underside of the nail plate has grooves that run along the length of the nail and help anchor it to the nail bed. Eponychium: The eponychium is more commonly known as the cuticle.
What are the parts of the nail?
The nail structure is divided into six parts: root, nail bed, nail plate, eponychium, paronychium, and hyponychium. Each of these six components has a specific function, and if a component of the nail structure is disrupted, the nail can look abnormal. Nail root: The root of the nail is also known as the germinal matrix.
Why do nails need to be protected?
The nails are intended to provide protection to fingers as well as aid in opening, scratching, and tearing. Just like other body areas, they’re subject to injury and disease. The following are some conditions that can affect the nail matrix.
What is the nail bed?
The nail bed is where the nail adheres to the finger. Other key elements of the nail include: Lunula. The white, half-moon cells at the nail’s base. Some people can only see the lunula on their thumbs while others cannot see theirs at all. Sterile matrix. This is the area of the nail above the lunula.
What is the term for a cancerous cell that grows in the nail?
Subungual melanoma (or nail matrix melanoma) is a condition where cancerous cells grow in the nail matrix. The cancerous cells can cause changes in pigments in the nail known as melanin. As a result, a distinct striped discoloration can grow from the nail matrix.
What is the germinal matrix of the finger?
Fingertip skin is connected to the sterile matrix. Germinal matrix. This is the area of the nail below the lunula (closest to the knuckle). An estimated 90 percent of nail production comes from the germinal matrix. This gives a natural curvature to the nail.
What causes a nail to turn dark?
Melanonychia is a broad descriptive term that can indicate a normal variation on nail color or something as serious as subungual melanoma (see below). Several conditions and events can cause melanonychia, including: 1 nail biting 2 psoriasis 3 pregnancy 4 Cushing syndrome 5 chemotherapy medications 6 nail infection
What is the nail matrix?
What is nail matrix? The nail matrix is the area where your fingernails and toenails start to grow. The matrix creates new skin cells, which pushes out the old, dead skin cells to make your nails. As a result, injuries to the nail bed or disorders that affect the matrix can affect your nail growth.
How long does it take for a nail to grow back?
Nail growth will usually resume at a faster rate and steady after about 100 days. You may notice the nail appears thicker than usual. The extent of the injury often depends on where it occurs. If you have a deep cut or trauma to the germinal matrix at the base of the nail, it’s possible the nail may never grow back.
What are the parts of the nail?
Nail anatomy is very complex and the sensitivity of our fingertips are correlated to the complexity of the parts of the nail; however, only the following main parts of the nail will be discussed: the matrix, nail plate, nail bed, nail root, lunula, eponychium, and the paronychium.
Why are nails considered human claws?
From an evolutionary point of view, nails can be considered as human “claws” that allow enhanced dexterity of the hands, such as scratching, clawing, picking, and pinching. Nails primarily serve as a source of protection for the tips of your fingers, which are medically termed “distal phalanges” (2). This area needs protection because thousands of nerve endings are concentrated within your fingertips, which serve as one of our main five senses – “touch”. Fingertips are used to determine whether our surroundings are safe, such as the temperature of surfaces, our food, and to serve as our “second eyes” in dark places or in those with compromised sight. The presence of the nail also serves to enhance the functional sensitivity of our fingernails by serving as straight edges for precision measurement (2). For example, telling the difference between a quarter and a dime would be difficult in the dark without your fingernails. In this case, you can think of your nails as tiny rulers! The nail also increases touch sensitivity due to its location over millions of open nerve endings and its ability to provide counter-pressure when you touch an object with the tip of your nail (2). This counterpressure stimulates the nerve endings underneath the nail bed.
How fast do nails grow?
Fingernails grow three times faster than toenails, and growth among the fingernails is relative to length, with the middle finger growing the fastest at 3-4mm per month. In contrast, toenails grow slower at a rate of 1mm per month and may take up to 18 months to fully develop a new nail (1). Nail growth rate is determined by intrinsic factors (e.g., genetic and hereditary aspects, age, and gender) and also by extrinsic conditions (diet, exercise, and season) (2). In fact, nails tend to grow slower in the winter than in the summer due to the abundance of vitamin D from the sun. Since nail growth is stimulated by blood circulation throughout the capillaries, the nails halt their growth after you die. Nails may only appear longer after death because loss of water in the skin causes your cuticles and the surrounding skin to shrink back (2).
Why do my nails turn purple?
Similar to lighter skin, melanocytes only appear after serious injuries to the nail (e.g., slamming your finger in the car door) (1). Millions of blood vessels are present underneath the nail bed, which is why your nail turns dark purple due to the ruptured blood vessels (2).
What is the function of a fingernail?
A healthy fingernail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries. It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger. Click to see full answer.
What are the functions of hair and nails?
Hair and nails are made of keratin, a tough protein. Nails act as protective plates over the fingertips and toes. Hair serves many functions such as acting as a filter and keeping the body warm.
How do nails form?
Beside above, how nails are formed? Nails start in the nail root, hidden under the cuticle. When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells.
What are the three parts of a nail?
A nail has three main parts: the root, plate, and free margin. Other structures around or under the nail include the nail bed, cuticle, and nail fold. Beside above, how nails are formed?
