What are Eponychium, Perionychium, and Hyponychium?

Eponychium, perionychium, and hyponychium refer to the skin structures that surround the nail, making the choice of skin surrounding the nail the correct answer.

The eponychium is the tissue located at the base of the nail, which protects the area between the nail and the epidermis from infections when the nail is growing. The perionychium encompasses the entire area surrounding the nail, including the lateral sides. The hyponychium is the skin under the free edge of the nail, which acts as a protective barrier and prevents pathogens from entering the nail bed.

These specific terms are essential for understanding nail anatomy and the overall health of nails, particularly in a nail technician context, where proper identification and care of nail structures are crucial for effective services. Understanding these components aids technicians in performing manicures, pedicures, and addressing various nail health concerns.
