________ Reflect the Orientation of Collagen Fibers in the Dermis

Question

________ reflect the orientation of collagen fibers in the dermis of the skin.
A) Tension lines
B) Tactile discs
C) Wrinkles
D) Stretch marks
E) All of these choices are correct

Accepted Answer

Tension lines, also known as cleavage lines or Langer's lines, are parallel to the orientation of collagen fibers in the dermis of the skin. These lines indicate the direction of the tension forces applied to the skin and are used by surgeons to plan incisions and wound closures. Tactile discs, wrinkles, and stretch marks may also be related to the dermal collagen fibers but do not specifically indicate their orientation.
