What is the proximal part of the nail?

What is the proximal part of the nail?

The word proximal means situated near the point of origin or attachment—which in nail anatomy is the matrix. To that end, the proximal nail fold is a fold of skin that forms a protective barrier to keep bacteria and infection from reaching the matrix. The eponychium is the visible “lip” of the proximal nail fold.

What is the proximal end of the nail?

The eponychium is the end of the proximal fold that folds back upon itself to shed an epidermal layer of skin onto the newly formed nail plate. The perionyx is the projecting edge of the eponychium covering the proximal strip of the lunula.

What is the proximal nail fold called?

eponychium
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.

What structure is at the proximal end of the nail bed?

The nail fold that meets the proximal end of the nail body forms the nail cuticle, also called the eponychium.

What internal portion of the nail is the site of nail formation?

Nail root: The root of the nail is also known as the germinal matrix. Its edge appears as a white crescent, known as the lunula. The root portion of this nail lies below the skin, underneath the nail, and extends several millimeters into the finger. It produces most of the volume of the nail and the nail bed.

What is Onychodermal band?

The onychodermal band is the point of strongest attachment between the nail and the underlying digit. Nail folds: Proximal and lateral. These are epithelial structures. The cuticle protects the matrix by sealing off the potential space between the nail plate and the proximal nail fold.

What is your nail attached to?

The nail is firmly attached to the nail bed beneath it. The nail and nail bed separate at the tip of the finger or toe, where the end of the nail sticks out. This allows us to use our nails as tools, for example for scratching. The nails are also an important part of the sense of touch.

Where is the Onychodermal band?

hyponychium
You are here: The onychodermal band is the “natural smile line” of the nail unit, where nail bed epithelium bunches up to pass through the tight seal of the hyponychium creating a grey line at the edge of the nail bed before the free edge of the nail plate.
