  1. ADIPOSE TISSUE

    Characteristics:
    adipocytes with compressed, laterally displaced nucles; blood capillaries visible; white adipose is unilocular and brown adipose is multilocular.

    Function: storage and metabolism of fat; cushioning of vital organs; insulation.

    Location: white adipose: subcutaneous tissues, omenta, mesenteries, pararenal tissue, and bone marrow; brown adipose: newborns and interscapular and inguinal regions.
  2. AREOLAR CONNECTIVE TISSUE

    Characteristics:
    loosely arranged with numerous collagen fibers, few elastic fibers, fibroblasts, macrophages, and other cellular components.

    Function: forms fascia that binds organs and organ components together.

    Location: most organs and tissues; expandable tubular structures such as ducts of glands.
  3. DENSE IRREGULAR CT

    Characteristics:
    thick, intertwined bundles of collagen fibers arranged haphazardly with fibroblasts and microphages present.

    Function: cushioning; provides attachment for ligaments.

    Location: dermis, capsules of organs, periosteum, perichondrium.
  4. DENSE REGULAR CT

    Characteristics:
    collagen bundles arranged in bundles with a regular, precise arrangement; fibers oriented in direction of pull.

    Function: joins bones together; muscles as well.

    Location: collagenous dense regular CT is found in tendons, ligaments, aponeurosis, and cornea; elastic is found in ligamentum nuchae and ligamentum flava.
  5. ELASTIC TISSUE

    Characteristics:
    concentric sheets of elastic fibers (elastic laminae) with wave-like appearance.

    Function: elasticity and recoiling action of aorta and large arteries.

    Location: aorta and large arteries.
