Eponíquio

O eponíquio is an area of specialized skin cells that include adult stem cells, is located on the ventral side of the prega ungueal proximal that produces the cutícula. This thin layer stretches from the nail matriz almost up to the queratinizado epiderme frame at the placa ungueal’s base. It is essential to understand that the eponychium and the cuticle, while closely related, are distinct and totally different entities; the eponychium is living tissue, whereas the cuticle that it produces, comprises the non-living skin cells that become one of the four selos de proteção and it lies between the nail plate and the proximal dobra da unha.

Differentiating the Eponychium from the Cuticle

The eponychium, residing on the ventral side of the proximal nail fold, is responsible for the production of the cuticle. Situated underneath the proximal nail fold, this layer extends from the nail matrix, reaching almost up to the keratinized epidermis frame at the nail plate’s base. The cuticle itself is composed of  non-living skin cells that are shed from the living eponychium and are bonded together with a sticky substance. This substance also adheres them strongly to the nail plate, creating a robust seal between the nail plate, the cuticle, and the proximal nail fold (PNF). This guardian seal plays a crucial role in protecting the delicate nail matrix and the leito ungueal from external elements.

The Importance of the Eponychium’s Seal

The eponychium’s primary function is to create the cuticle that becomes a strong seal between the epidermis of the proximal nail fold and the nail plate. This seal, together with the proximal nail fold, pregas ungueais lateraise hiponíquio, formulários a protective barrier for the nail matrix (you hear us talking about the 4 guardian selos all of the time). It helps prevent the infiltration of infections, alergênicose patógenos into the delicate areas of the nail bed and matrix, thus safeguarding overall nail health.

Advisory Against Cutting the Eponychium

Cutting into the proximal nail fold or otherwise compromising the eponychium is not advisable as it damages the integrity of the nail seal. Such actions expose the derme beneath the keratinized skin frame and can lead to infections within the unidade de pregos. Disturbing the eponychium might also trigger the skin’s defence mechanisms, prompting thicker regrowth, which can further complicate cuidados com as unhas and health. It’s crucial to preserve the eponychium to ensure it continues to fulfil its role in maintaining the nail’s health and protection.
