What is the Eponychial fold?
The eponychial fold covers the softer and less cornified proximal nail plate. The cells of this proximal plate are not completely anucleate and project a white color because of the nuclear parakeratosis, which occurs only at the level of the germinal matrix.
What is the nail fold?
The nail fold is the tissue that encloses the nail matrix at the root of the nail. It attaches the nail to the rest of the skin through the protective cuticle. Paronychia is a common infection that afflicts the skin around the nails.
What is the function of the lateral nail fold?
The lateral nail fold overlaps the nail on the sides, helping to anchor the nail body. The nail fold that meets the proximal end of the nail body forms the nail cuticle, also called the eponychium.
Where is the proximal nail fold?
The proximal nail fold is a wedge of thickened skin at the base of the nail. It’s found on both your fingernails and toenails. The skin folds over the nail matrix and the base of the nail. The nail matrix produces the hard nail.
Will an avulsed nail grow back?
Losing a toenail or fingernail because of an injury is called avulsion. The nail may be completely or partially torn off after a trauma to the area. If completely removed, fingernails may take 6 months to grow back. Toenails may take 12 to 18 months to grow back.
Can a nail fold grow back?
Skin has amazing restorative powers, so if the frame or the proximal nail fold are cut, then it will recover. However, skin if continually cut, will grow thicker, to protect itself, and grow calluses and scar tissue.
What is the difference between eponychium from Hyponychium?
The skin proximal to the nail that covers the nail fold is the eponychium. A junction is formed between the sterile matrix and the fingertip skin beneath the nail margin. This area is referred to as the hyponychium.
What shape of nail is considered the weakest shape?
Almond
Almond. These nails are the weakest natural nail shape. This shape is very feminine and makes your hands look longer.
What is the average nail growth per month?
3.47 millimeters
Your fingernails grow at an average rate of 3.47 millimeters (mm) per month, or about a tenth of a millimeter per day. To put this in perspective, the average grain of short rice is about 5.5 mm long. If you happen to lose a fingernail, it may take up to six months for that nail to completely grow back.
Should you remove proximal nail fold?
Can you cut into the proximal nail fold? No, that is not recommended. The proximal nail fold is an important nail seal and by cutting it away and exposing the dermis behind the frame of keratinised skin, you risk allowing infection into the nail unit plus the skins defenses will encourage it to grow back thicker.
How long does it take for nail folds to grow back?
Fingernails can regrow entirely in three to six months. Fingers or toes that have sustained injuries that affect the nail bed and the matrix grow more slowly than unaffected nails for about three months.
Where are the sterile matrix and eponychium located?
Underneath the nail plate there lies the nail bed. The white arc on the nail just distal to eponychium is the lunula. The nail bed distal to this is the sterile matrix and proximal to that is the germinal matrix. The nail fold consists of the germinal matrix and eponychium.
What is the role of the paronychium in nail growth?
The term paronychium refers to the fold on each lateral aspect of the nail [Figure 1]. The germinal matrix is responsible for 90% of the nail growth. The nail is formed by the keratinous mass pressed between the nail bed and the eponychial fold and grows distally. The eponychium contributes to the shine of the nail.
What does eponychium stand for in medical terms?
Eponychium refers to the soft tissue proximally on the dorsum of nail continuing to the dorsal skin. The fine filamentous material attaching nail to eponychial fold is the nail vest. Underneath the nail plate there lies the nail bed. The white arc on the nail just distal to eponychium is the lunula.
What was the end of reconstruction in the south?
The End of Radical Reconstruction. The end of Reconstruction was a staggered process, and the period of Republican control ended at different times in different states. With the Compromise of 1877, army intervention in the South ceased and Republican control collapsed in the last three state governments in the South.
