(Loose) Areolar Connective Tissue


  1. Elastic fiber (looks as if someone drew a line on the slide with a sharp pencil)
  2. Collagen fibers (arranged in a loose fashion)


  • Fibers (collagen, elastic, and reticular) are loosely organized, so this tissue can distort without damage.
  • Elastic fibers make the tissue resilient. This tissue returns to its original shape when distorted.
  • The matrix is thick/viscus (the consistency of clear maple syrup)
  • There are many cells that can be found in this tissue:
    1. Fibroblasts (that make the fibers)
    2. Mast cells (that initiate inflammatory response)
    3. Macrophages (that patrol for and destroy foreign invaders like bacteria)
    4. White blood cells (that patrol for and destroy foreign invaders like bacteria)


  • Provides padding/cushion
  • Has elastic properties to allow for movement
  • This tissue is one of the packaging materials of the body.


  • Forms a layer that separates skin from deeper structures.
  • Forms lamina propria of mucus membranes (the foundation layer that connects the mucus membranes to what lies underneath)
  • Packages organs
  • Surrounds capillaries
