Transcript

  • 1. Muscles moving the Upper Extremities
  • 2. Muscles that move the Humerus
    Pectoralis major
    Action:
    Flexes, adducts and rotates arm medially at shoulder
    Origin:
    Clavicle, sternum, costal cartilage of upper ribs
    Insertion:
    Humerus-greater tubercle
  • 3. Latissimus dorsi
    Action:
    Extends, adducts and rotates humerus medially, retracts the shoulder (swimmers muscle)
    Origin:
    Spine of sacral lumbar and lower thoracic vertebra. Iliac crest, and bottom 4 ribs.
    Insertion:
    Intertubercular groove of the humerus.
  • 4. Deltoid
    Action:
    Flexes and medially rotates arm, abducts arm, extends and laterally rotates arm.
    Origin:
    acromian process, spine of scapula, clavicle
    Insertion:
    Deltoid tuberocity of the humerous
  • 5. Supraspinatus
    Action:
    Abducts arm
    Origin :
    Supraspinous fossa of scapula
    Insertion:
    Greater tubercle of humerus
  • 6. Infraspinatus
    Action:
    Adducts and laterally rotates arm
    Origin:
    Infraspinous fossa of scapula
    Insertion:
    Greater tubercle of humerus
  • 7. Teres minor
    Action:
    Adducts and laterally rotates arm
    Origin:
    upper lateral border of scapula
    Insertion:
    Greater tubercle of humerus
  • 8. Teres major
    Action:
    Medially rotates and adducts arm
    Origin:
    Inferior angle and lateral border of scapula
    Insertion:
    Crest of lesser tubercle of the humerus
  • 9. Muscles that act on the forearm
    Triceps brachii
    Action:
    Extend forearm
    Origin:
    Long head-infraglenoid tubercle of the scapula
    Lateral Head-posterior surface above radial groove.
    Middle Head-posterior humerous below radial groove.
    Insertion:
    Olecranon process of the Ulna
  • 10. Pass, Fail, Pass, FailPronator TeresFlexor carpi radialisPalmaris longusFlexor carpi ulnaris
  • 11. Pronator Teres
  • 12. Flexor carpi radialis
    Flexor carpi ulnaris
  • 13. Palmaris longus
  • 14. THE 3 B’S THAT BEND THE ELBOW:
    Biceps brachii, Brachioradialis, Brachialis
  • 15. Biceps brachii
    Action:
    Flex and supinate the forearm
    Origin:
    Short head- goes to the corocoid process of scapula
    Long head-supraglenoid tubercle of scapula.
    Insertion:
    radiotuberocity and fascia of forearm
  • 16. Brachioradialis
    Action:
    Flexes forearm
    Origin:
    lateral supercondylar ridge of humerus.
    Insertion:
    Styloid process of radius
  • 17. Brachialis
    Action:
    Flexes forearm
    Origin:
    The distal anterior surface of the humerus.
    Insertion:
    The coronoid process of the ulna
  • 18. Pronators and Supinator
    Pronators
    • Pronator Quadratus
    Action: Pronates the hand
    Origin: the distal 4th of the ulna
    Insertion: distal 4th of the radius
    • Pronator Teres 
    Action: Pronates forearm
    Origin: the medial epicondyle of the humerus and coronoid process of the ulna
    Insertion: Lateral surface of the radius.
  • 19. Pronators
    Pronator quadratus
    Pronator teres
  • 20. Supinator
    • Action:
    • 21. Supinates forearm
    • 22. Origin:
    • 23. the laterally epicondyle of the humerous and crest of the ulna.
    • 24. Insertion:
    • 25. Lateral surface of the proximal 3rd of the radius
  • MUSCLES THAT MOVE WRIST, HAND AND DIGITS
  • 26. Palmar Interosseous muscles
    Action:
    Adduct digits 2,4 and 5
    Origin:
    palmar surface of metacarpals 2,4,5
    Insertion:
    sides of proximal phalange bases for fingers 2,4,5
  • 27. Dorsal Interosseous Muscles
    Action:

    Origin:
    adjacent sides of metacarpal bones.
    Insertion:
