What is the visible part of a nail often referred to as?

The visible part of a nail is commonly referred to as the nail body. This term describes the portion of the nail that extends beyond the nail bed and is what is typically seen and regarded as the nail itself. The nail body is made up of keratin, which is a protein that is crucial for the strength and durability of the nail.

In contrast, the nail tip is not a standard anatomical term used in the context of nail structure, and while it might refer informally to the end of the nail, it is not the formal term used in nail anatomy. The nail fold refers to the folds of skin that are next to the nail, providing support and protection. The nail plate is another correct term that refers to the entire flat portion of the nail, but it is less specific than "nail body," which indicates just the area you can see externally. Thus, the correct identification of the visible part of the nail is the nail body.
