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 eponychium?
Noun. eponychium (plural eponychia) (anatomy) The thickened layer of skin adjoining fingernails and toenails, particularly at the base of the nail.
What is the eponychium and how is it formed?
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.
What is eponychium in the parts of the nail?
The eponychium is the visible “lip” of the proximal nail fold. It forms a seal with the nail plate, protecting the matrix from harmful bacteria. Many people mistakenly refer to the eponychium as the cuticle, which is why the adage, 'Never cut the cuticle!

proximal nail foldThe eponychium is an area of specialised skin cells on the ventral side of the proximal nail fold that produce the cuticle.
What is the common name for eponychium?
The cuticle, also known as the eponychium, is an extension of the stratum corneum from the proximal nail fold [1-3].
What is the difference between cuticle and 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 are the parts of the nail and their functions?
Nail Anatomy 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. Nails grow from a deep layer of living epidermal tissue, known as the nail matrix, at the proximal end of the nail. The nail matrix surrounds the nail root.
Is the eponychium live tissue?
What many people refer to as the cuticle is actually the eponychium. This living tissue forms a seal between the nail plate and the skin. On the nail, it's the visible rim between the skin of the finger and the nail plate itself.
Does the eponychium protect the Matrix?
Eponychium: is the skin, the living tissue. It's there to protect the Matrix from infections and bacterials. So if the skin is attached to the nail plate it's still the Eponychium.
Can you cut the eponychium?
Don't cut the eponychium, ever. Hangnails and dry, dead skin may be removed carefully. Deal with thick cuticlesby using an exfoliant, cuticle remover, or allowing the cuticle to repair itself with the aid of moisturizers. Do remove excess true cuticle from the nail plate.
How do you lift eponychium?
Without further advancement, the scalpel should be rotated 90 degrees, with the sharp side toward the nail, gently lifting the eponychium from its attachment to the nail. At this point, pus should slowly extrude from the abscessed cavity.
What is the difference between eponychium from 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.
Is the eponychium live tissue?

What is the difference between the cuticle and the eponychium?
The eponychium is an area under the proximal nail fold where the dead skin cells of the proximal nail fold are shed and where they are bonded together with a sticky substance that also sticks them strongly to the nail plate. The strong seal between the nail plate, the cuticle and the PNF is what forms an important seal of the nail unit protecting the delicate matrix and the nail bed

Living skin underneath the proximal nail fold, is a thin layer that stretches from the nail matrix almost up to the frame of keratinised epidermis at the edge of the proximal nail fold at the base of the nail plate.
What is the name of the layer of the epidermis that is in direct contact with the nail root?
1. The corneal layer of epidermis overlapping and in direct contact with the nail root proximally or the sides of the nail plate laterally, forming the undersurface of the nail wall or nail folds. Synonym (s): hidden nail skin, perionychium
What is the thin layer of the epidermis that precedes and covers the nail plate in the embryo?
1. The thin, condensed, eleidin-rich layer of epidermis that precedes and initially covers the nail plate in the embryo. It normally degenerates by the eighth month, except at the nail base, where it remains as the cuticle of the nail.
