Ess 3092 week 4 student (shoulder)

  1. 1. +ESS 3092: KINESIOLOGYWeek 3
  2. 2. +3x5 cardFront side:What would you like to review onWednesday?Back side:Write an exam question for Exam 1. Pleaseprovide the answer*If your question is chosen, you will receive 1bonus point on your exam3
  3. 3. +Your ideas for movement analysis:1. Free throw2. Gymnastics3. Boxing4. Swimming (freestyle)5. Running hurdles6. Olympic lifts7. Cycling4
  4. 4. +Shoulder5
  5. 5. +Humerus (Arm) The humerus articulates withthe scapula at the shoulder andwith the radius andulna at the elbow6
  6. 6. The Glenohumeral Joint7
  7. 7. Bones - Scapular Landmarks supraspinatus fossa infraspinatus fossa spine of the scapula glenoid cavity inferior angle superior angle medial border lateral border8
  8. 8.  subscapular fossa glenoid cavity coracoid process acromion process9
  9. 9. Bones - Humeral LandmarksHeadGreater tubercleLesser tubercleDeltoid tuberosity10
  10. 10. +Glenohumeral JointGreatest ROM significant amount of laxityGlenoid Fossa: ¼ size of humeral headGlenoid labrum cartilaginous ring just inside the periphery contact area to 70%The price of mobility is reduced stability11

  16. 16. The Rotator CuffSITS= Subscapularis, infraspinatus, supraspinatus, & teresminor muscles Attach to front, top, & rear of humeral head Point of insertion enables humeral rotation Vital in maintaining humeral head within glenoid fossa whilemore powerful muscles move humerus through its wide ROM17
