2.  Most diverse  Never exposed to outside  Vascular—have blood vessels  Receptors for pain, pressure and temperature

4.  Support/Protection  Transportation  Storage of energy reserves (Adipose cells— AKA fat cells)  Defense

6.  Cell Types  Fibroblasts  Most abundant  Produce and maintain connective tissue  Macrophages  Engulf damaged cells and wastes  Adipocytes  Fat cells  Mast Cells  Release chemicals to start immune response

7.  Collagen Fibers  Strong and flexible  Elastic Fibers  Will stretch  Reticular Fibers  Thin

8.  Fills in space between cells  Slows bacteria and pathogens

10.  Genetic  Abnormal fibrillin—gives connective tissue strength and elasticity  Tall with abnormally long arms, legs and fingers  Abnormal cardiovascular system  Weak aorta—may burst  Sudden, fatal loss of blood

11.  Areolar Tissue  Least specialized  Increased blood supply  Separates skin from muscle  Pads  Allows movement  Supplies blood to epithelia

13.  AKA: Fat  Loose Connective Tissue  Padding  Shock absorption  Insulation  Energy reserve  Collects in sides, buttocks, breasts and abdomen

15.  Weight loss = deflated adipocytes  Easily regain these cells b/c the cells are still there  Liposuction—remove adipocytes

16.  Mostly collagen  Tendons—attach muscles to bone  Ligaments—attach bone to bone
