What is the function of the epidermis around the base of a nail?

What is the function of the epidermis around the base of a nail?

The Cuticle: The overlapping epidermis around the base of the nail is called the cuticle. The function of the cuticle is to protect the matrix from infection. The Nail Walls: These are the folds of the skin overlapping the sides of the nails. The function of the nail wall is to protect the nail plate edges.

What is the structure of the nail plate?

Nail Plate: The nail plate is composed of layers of keratinized skin cells. The layers are packed very closely together with fat but very little water content. The nail gradually grows over the nail bed and becomes free edge. There are no blood vessels or nerves in the nail plate.

Where does the eponychium meet the nail body?

The nail fold that meets the proximal end of the nail body forms the nail cuticle, also called the eponychium. The nail bed is rich in blood vessels, making it appear pink, except at the base, where a thick layer of epithelium over the nail matrix forms a crescent-shaped region called the lunula (the “little moon”).

Where does the nail body and cuticle meet?

The nail body forms at the nail root, which has a matrix of proliferating cells from the stratum basale that enables the nail to grow continuously. The lateral nail foldoverlaps 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 the band of epidermis at the base of the nail called?

What is the band of epidermis at the base and side of the nail plate that covers the nail root called? A- Basal layer B- Cuticle C- Paronychium D- Stratum corneum Cuticle What is the deepest region of the epidermis? A- Basal layer B- Subepidermis C- Stratum corneum D- Epithelium Basal layer The soft tissue surrounding the nail border is called:

How does the band on the top of the fingernail work?

A band of bunched up tissue located behind the hyponychium. This band improves the ability of the hyponychium to prevent pathogens from infecting the nail bed. The onychodermal band works in the same way as the proximal fold on the top surface of the nail.

What are the different parts of a fingernail?

NAIL ANATOMY – Different Parts of Fingernail 1 Nail Anatomy – The Different Parts of the Fingernail. 2 Matrix. Where new nail plate cells are created and the nail plate begins to form. 3 Lunula. A bluish-white, opaque area that is visible through the nail plate. 4 Eponychium. Living skin at the base of the nail plate that covers the matrix area.

How is the cuticle attached to the nail plate?

A thin layer of dead tissue riding on the nail plate to form a seal between the nail plate and eponychium to prevent pathogens from infecting the matrix area. The cuticle pulls away from the underside of the eponychium and attaches tenaciously to the nail plate. The cuticle should NOT be confused with the “eponychium”.
