Transcript

  • 1. Scapula andGlenohumeral JointMajor Assignment By Michelle & Nicole
  • 2. Scapular Elevation Muscles★ Levator Scapulae★ Rhomboid Minor★ Rhomboid Major★ Trapezius Upper Fibres
  • 3. Scapular Elevation
  • 4. Levator ScapulaeO- tp of first four cervical vertebraeI- superior angle/ vertebral border of scapulaA- Scapular elevation, assists scapular downwardrotation
  • 5. Rhomboid MinorO- sp of C7 to T1 and nuchal ligamentI- vertebral border of scapulaA- scapular elevation, retraction, scapular downwardrotation
  • 6. Rhomboid MajorO- sp of T2 to T5I- vertebral border of scapula, between spine andinferior angleA- scapular elevation, scapular retraction, scapulardownward rotation
  • 7. Trapezius Upper FibresO- occipital bone and ligamentum nuchaeI- lateral clavicle and acromion process of scapulaA- scapular elevation, scapular upward rotation
  • 8. Medial/Internal Rotation of GH Muscles★ Subscapularis★ Deltoid (Anterior Head)★ Latissimus Dorsi★ Teres Major★ Pectoralis Major
  • 9. Medial/Internal Rotation of GH
  • 10. SubscapularisO- subscapular fossa of scapulaI- lesser tubercle of humerusA- GH medial rotation, GH adduction
  • 11. Deltoid (Anterior Head)O- lateral clavicleI- deltoid tuberosity of humerusA- GH medial rotation, flexion, horizontal adduction ofGH, assists GH abduction
  • 12. Latissimus DorsiO- sp of T6 to L5, sacrum, lumbar dorsal fasciaI- medial lip of bicipital groove of humerus, anteriorsideA- GH medial rotation, GH extension, slight GHadduction
  • 13. Teres MajorO- inferior angle of scapulaI- medial lip of bicipital groove of humerusA- GH medial rotation, GH extension, GH adduction
  • 14. Pectoralis MajorO- medial half of clavicle, anterior sternum, costalcartilageI- greater tubercle and lateral lip of bicipital grooveof humerusA- GH medial rotation, GH horizontal adduction, GHadduction, GH flexion (clavicular portion)
