What is the fold of the skin on either side of the nail groove called?

  1. Nail wall

  2. Nail bed

  3. Nail matrix

  4. Nail fold

The correct answer is: Nail wall

The fold of skin that lies on either side of the nail groove is known as the nail wall. This structure is important in the overall health of the nail as it provides support and helps to protect the area where the nail grows. The nail wall plays a crucial role in the nail's anatomy by framing the edges of the nail plate and assisting in the process of nail growth. The nail bed is the underlying skin to which the nail is attached and is located beneath the nail plate. The nail matrix is the tissue under the base of the nail that produces new cells, leading to nail growth. The nail fold refers to the skin that overlaps the nail plate at its sides, while the nail wall specifically pertains to the structures on either side of the nail groove. Understanding these terms helps in grasping the anatomy and function of the nail, ensuring proper technique and care in nail technology.
