What is the name of the tissue located beneath the free edge of the nail?

The tissue located beneath the free edge of the nail is called the hyponychium. This specialized area serves as a protective barrier that prevents pathogens from entering the nail bed and contributes to the overall health of the nail. It is the junction between the skin and the nail, providing a seal that helps to safeguard the sensitive underlying structures.

The hyponychium also plays a role in the nail's growth and development by supporting the nail plate as it extends beyond the fingertip. Understanding this tissue is important for nail technicians, as it helps in performing services accurately and safely while preventing damage to the nail and surrounding skin.

The other choices refer to different parts of the nail anatomy. The nail matrix is located at the base of the nail and is responsible for nail growth, while the nail bed is the skin beneath the nail plate. The eponychium is the cuticle area at the base of the nail that protects the matrix. Each of these structures plays unique roles in nail health, but the hyponychium specifically pertains to the area directly under the free edge of the nail.
