Quizplus · Accepted Answer

Cleavage lines, or tension lines, are based on the arrangement of collagen fibers in the dermis layer of the skin. These lines are important for surgical incisions because they can affect the healing process and the appearance of scars. By making incisions parallel to these lines, tension on the wound is minimized and scarring can be minimized.
