Clinical aspect of skin

The skin is the gateway to any of the internals structures of the body. It has the following types
  • Thin
  • Thick
  • Glabrous (no hair)
  • Hairy

Skin lines

The following are lines on the external surface of skin

  • Tension lines (skin creases)
  • Flexure lines (skin joints)
  • Papillary ridges
  • Intrinsic scarring
  • Surgical-medical lines
    • Langer's lines
    • Kraissl's lines
    • Blaaschko's lines

The skin's collagen fibers are deposited in such a way as to run parallel to each other in the so called Langer's lines. For example the skin of the anterior abdominal wall is lax. It is distensible also to accommodate the ever increasing abdominal cavity. It has Langerís lines running transversely and incision made on those lines (e.g. Pfannenstiel) heals with minimum of scar tissue formation, although

The skin also represents the contor of surface anatomy of any region of the body.
