What is the lateral fold commonly known as?

The lateral fold is commonly referred to as the sidewall. This is the area of skin that runs along the sides of the nail. Its primary function is to provide support and protection to the nail as it grows.

Understanding the anatomy of the nail is essential for nail technicians, and recognizing the sidewalls helps in performing proper nail care and manicure techniques. Maintaining the health of the sidewalls contributes to well-groomed nails and can help prevent hangnails or other issues that may arise from neglect.

The other terms relate to different parts of the nail structure: the cuticle refers to the dead skin that overlaps the nail plate, the nail matrix is the part of the nail bed that produces the nail itself, and the eponychium is the tissue at the base of the nail plate that helps protect the nail matrix. Each term describes distinct elements of nail anatomy, underscoring the importance of knowing the correct terminology for effective nail services.
