  • papillary and reticular
    The dermis of integument (skin) is a great example of both loose and dense irregular connective tissue. This creates two regions
  • papillary zone
    directly below the epidermis and this is where loose connective tissue with blood vessels, small nerve bundles and/or fibers, mast cells and histiocytes can be observed
  • papillary ridges or dermal papillae
    The projections of the loose connective tissue which extend upward into the epidermis are
  • epidermal pegs
    the extensions of the epidermis down are referred to as
  • Why, what is the function of these ridges/pegs?
    Bring nourishment to the hair follicles and bring oxygen to the epidermis cell.
  • Fingerprints
    At the tips of human fingers, these ridges create something unique, what is that?
  • the reticular zone of dermis consists of dense irregular connective tissue
  • What function does this portion of the dermis provide?
    Provide structure for fibroblast secretions collagen.
  • Subcutaneous or hypodermis region
    a great place to find adipocytes
  • Adipose
    The prevailing tissue that exists in this region is
  • elastic and collagenous fibers
    elastic and collagenous fibers
  • Fibroblast
    What cells are creating these fibers?
  • How does the function of this collagen bundles connective tissue differ from the others?
    Dense regular connective tissue resists physical stress in one direction. Loose connective tissue and dense irregular issue allow movement of tissue in multiple directions.

  • Look at one other slide available to you and note the connective tissue. Would you call it loose or dense? Regular or irregular?
