Abrasion
It is a destruction of the skin, which involves the superficial layers of
the epidermis only. They are of 4 types:

  1. Scratches- its a abrasion with length but no significant width or a a
    very superficial incision.
  2. Grazes-most common. They occur when there is movement
    between the skin and some rough surface in contact with it.
  3. Pressure or friction abrasion- they are caused by crushing of the
    superficial layers of the epidermis and are associated with a bruise
    of the surrounding area.
  4. Impact or contact abrasion- they are caused by impact with a rough
    object, when the force is applied at or near a right angle to the skin
    surface.
  5. Patterned abrasion- impact abrasion and pressure abrasion
    reproduce the pattern of the object causing it and are called
    Patterned abrasion.
