  • The perinychium includes the nail, the nailbed, and the surrounding tissue.
  • The paronychia is the lateral nail folds
  • The hyponychium is the palmar surface skin distal to the nail.
  • The lunula is that white semi-moon shaped proximal portion of the nail.
  • The sterile matrix is deep to the nail, adheres to it and is distal to the lunule.
  • The germinal portion is proximal to the matrix and is responsible for nail growth.
