eponíquio

Eponíquio refers to the layer of epidermal cells at the base of the nail that is responsible for its growth. It is located beneath the nail fold and extends forward to cover the nail matrix. The eponychium is a thin, non-pigmented cuticle that protects the nail matrix from infection and damage. It is composed of stratified squamous epithelium and is continuously shed as the nail grows.

The nail matrix, also known as the germinal matrix, is where the nail plate is formed. The eponychium is crucial for this process as it protects the matrix and ensures proper nail development. Any trauma or damage to the eponychium can lead to abnormalities in nail growth or shape.

In some individuals, the eponychium may be more prominent or thicker, giving the appearance of a larger cuticle. This is a normal variation and does not indicate any underlying medical condition. Proper nail care involves avoiding excessive cutting or manipulation of the eponychium to prevent damage and infection. Gentle pushing back of the cuticle after softening it with warm water or cuticle remover is generally recommended.
