What is the importance of the eponychium and hyponychium?
What is the importance of the eponychium and hyponychium?
The hyponychium is a strong seal at the end of the finger and under the free edge. The eponychium is an area under the proximal nail fold that sheds the dead skin cells of the proximal nail fold called the cuticle. The cuticle and proximal nail fold form another strong and important seal of the nail unit.
Where on the nail is the hyponychium and the eponychium?
The epithelium underlying the nail bed and nail plate, forms a continuous fold, first forming the cuticle or eponychium (epo=above) at the proximal end of the nail, overlying the nail plate , then the nail bed underneath the nail plate and finally the hyponychium (hypo=below); a thickened region of stratum corneum that …
What is the hyponychium?
The hyponychium is the skin just under the free edge of your nail. It’s located just beyond the distal end of your nail bed, near your fingertip. As a barrier from germs and debris, the hyponychium stops external substances from getting under your nail.
What are the 7 Structure of nails?
A fingernail consists of several parts including the nail plate (the visible part of the nail), the nail bed (the skin beneath the nail plate), the cuticle (the tissue that overlaps the plate and rims the base of the nail), the nail folds (the skin folds that frame and support the nail on three sides), the lunula (the …
What is the function of the eponychium?
The cuticle, also known as the eponychium, is an extension of the stratum corneum from the proximal nail fold [1-3]. It forms a seal that prevents allergens, irritants, and pathogens from entering the potential space between the distal skin of the digit and the nail plate [4-5].
What role does the eponychium play?
In human anatomy, the eponychium is the thickened layer of skin at the base of the fingernails and toenails. It can also be called the medial or proximal nail fold. Its function is to protect the area between the nail and epidermis from exposure to bacteria.
How do you remove eponychium?
First, soften the eponychium and make it pliable. This may be done with a warm water soak or a hot penetrating oil soak. Instead of trimming the offending eponychium, reduce it with a cuticle remover. “This breaks down the bonds between the dry skin cells and makes them easy to remove with a curette,” says Schoon.
Is eponychium same as cuticle?
The eponychium differs from the cuticle; the eponychium comprises live skin cells whilst the cuticle is dead skin cells. Its function is to protect the area between the nail and epidermis from exposure to bacteria. The vascularization pattern is similar to that of perionychium.
What is the other term of eponychium?
What is the hyponychium made of?
The hyponychium is the area of epithelium, particularly the thickened portion, underlying the free edge of the nail plate on the nail. Its proximal border is immediately distal to distal limit of nail bed—a.k.a. the onychodermal band (the line along the interface of the nail bed and the nail plate).
Is the eponychium the cuticle?
What is the difference between the nail cuticle and the eponychium?
The eponychium differs from the cuticle; the eponychium comprises live skin cells whilst the cuticle is dead skin cells. Its function is to protect the area between the nail and epidermis from exposure to bacteria.
What is the difference between paronychium and hyponychial?
Paronychium refers to the skin on each side of the nail, and hyponychium refers to the skin distal to the nail bed. The eponychium is the skin proximal to the nail that covers the nail fold. Extending distally from the eponychium onto the nail is the nail vest or cuticle.
What is the eponychium of the nail?
The eponychium is the skin proximal to the nail that covers the nail fold. Extending distally from the eponychium onto the nail is the nail vest or cuticle.
Where is the hyponychium on the nail?
It’s located just beyond the distal end of your nail bed, near your fingertip. As a barrier from germs and debris, the hyponychium stops external substances from getting under your nail. The skin in this region contains white blood cells to help prevent infection.
What is perionychium in nails?
B, The perionychium includes the paronychium, eponychium, hyponychium, and nail bed. The germinal matrix produces about 90% of the nail, an important point in reconstruction of the nail bed.
