In some cases, the eponychium may partially or completely cover the lunula.

Together, the eponychium and the cuticle form a protective seal.

In human anatomy, cuticle (also called eponychium) refers to several structures.

The perionyx is the projecting edge of the eponychium covering the proximal strip of the lunula.

The eponychium is the small band of epithelium that extends from the posterior nail wall onto the base of the nail.

On the loss of a fingernail or thumbnail, the area under the eponychium (cuticle) can be packed with this type of dressing to act as a stent.

The cuticle on the nail plate is dead cells and is often removed during manicure, but the eponychium is living cells and should not be touched.

In human anatomy, the eponychium [Greek epi (on, upon) + onychion (little claw)], is the thickened layer of skin surrounding fingernails and toenails.

In hoofed animals, the eponychium is the deciduous hoof capsule in fetuses and newborn foals, and is a part of the permanent hoof in older animals.
