What term signifies the visible portion of the nail that extends beyond the fingertip?

The term that signifies the visible portion of the nail that extends beyond the fingertip is the free edge. The free edge is the part of the nail that is not attached to the nail bed and is the most distal portion of the nail. It plays an important role in everyday activities, as it can protect the sensitive tips of the fingers and is often trimmed or shaped during manicures.

The nail bed is the area below the nail plate that supports the nail. The nail matrix is located beneath the cuticle and is where nail growth occurs. Eponychium refers to the fold of skin at the base of the nail, which protects the matrix from infection. Understanding these terms helps in recognizing the structure and function of the nail as a whole, as well as in ensuring proper nail care and maintenance.
