Pterygium, in the context of nail anatomy, refers to an abnormal growth of skin that can occur at the nail bed or eponychium, leading to the adhesion of the proximal nail fold to the nail plate. When there is a severe injury to the eponychium or hyponychium, it disrupts the normal nail growth and can result in the formation of pterygium. The eponychium is the living tissue at the base of the nail, and damage to this area can significantly affect the health and appearance of the nail. The hyponychium, located beneath the free edge of the nail, also plays a role in protecting the nail bed.

Injuries to these specific parts can lead to improper nail formation or even scarring, which contributes to the development of pterygium. As a result, understanding the functions and anatomy of these areas is essential for recognizing how their damage can impact nail health and lead to conditions like pterygium. Other options do not directly relate to this condition's specific development.
