What is the thin layer of tissue that attaches the nail plate to the nail bed known as?

The thin layer of tissue that attaches the nail plate to the nail bed is referred to as bed epithelium. This layer is crucial because it provides the necessary support and nourishment to the nail as it grows. The bed epithelium plays a vital role in maintaining the health of the nail, ensuring a strong attachment between the nail plate and the underlying skin.

In this context, the nail matrix is the tissue beneath the base of the nail responsible for nail growth, while the cuticle is the layer of dead skin at the base of the nail that protects the area between the skin and the nail plate from infection. The hyponychium, on the other hand, is the skin beneath the free edge of the nail that serves as a barrier to protect the nail bed. Understanding these definitions highlights the unique function of the bed epithelium in nail health and attachment.
