2.  Vertebrae separated by intervertebral discs  Shock Absorbers  Prevents bone to bone contact  Herniated disc  Disc extends outwards  Reduces disc function

5.  Shoulder Joint  Greatest motion in body  Most dislocated joint  Bursitis—inflammation of bursa  Restrict motion  Painful  Elbow Joint—Extremely stable

9.  Hip Joint  Absorbs shock  Denser and stronger than shoulder  Extremely stable  Less movement than shoulder

12.  Usually 60+  Osteoporosis weakens femur  Usually occurs with hip dislocation or pelvic fractures  Takes long time to heal

14.  Medial and lateral menisci—cushion  Bursae—reduce friction  Patellar ligament—supports
