  1. The Upper Extremity

  2. Do Now • List as many muscles in the arm as you can

  3. Homework Review • Clear your desk • 1 Question quiz • What is the fleshy muscle of the arm that is a favorite for intramuscular injections (shots)? • Write on piece of paper with name and pass it in

  4. Homework • Create Flashcards for the following muscles • Triceps Brachii • Brachialis • Brachioradialis • Pronator Teres • Extensor Carpi Radialis • Extensor Carpi Ulnaris

  5. Review

  6. Review • Deltoid • Pectoralis Major • Biceps Brachii • Rotator Cuff • Supraspinatus • Infraspinatus • Subscapularis • Teres Minor

  7. Injuries of the Shoulder • Biceps Tondonitis • Shoulder Impingement

  8. Biceps Tendonitis • Overuse of the biceps • Opposite of overuse? • 2 origins of the bicep • Coracoid process • Glenoid tubercle • Very common in swimmers, pitchers

  9. Shoulder impingement • Commonly, an overuse injury • Muscles inflame in the shoulder and not enough space is allowed for muscles to swell • Compress the nerve • Sometimes it is a structural abnormality • Acromion Process hooks downward to close space

  10. Shoulder Impingement

  11. Shoulder Impingement

  12. The Elbow/Forearm

  13. Elbow/Forearm • All “flexors” are palmar side of arm • Forearm • Extensors are opposite and on the dorsal side of the forearm

  14. Triceps Brachii • O: Glenoid Cavity of Scapula • I: Olecranon process of ulna • A: Forearm extensor; antagonist of biceps brachii

  15. Triceps Brachii

  16. Brachialis • O: Anterior surface of distal humerus • I: Coronoid process of ulna • A: Arm flexor

  17. Brachialis

  18. Brachioradialis • O: Distal humerus • I: Base of styloid process of radius • A: Forearm flexor (thumb up)

  19. Brachioradialis

  20. Extensor Carpi Radialis • O: Lateral humerus • I: Second and third metacarpal • A: Extends and abducts wrist Extensor Carpi Ulnaris • O: Lateral epicondyle of humerus • I: 5th metacarpal • A: Extends and adducts the wrist

  21. Ulnaris/Radialis

  22. Movement Analysis Project • Each group will analyze a movement of their choice • Sports/Functional movement • Groups of no more than 4, but no less than 2

  23. Homework • Create your group • Come to class with the movement your group will analyze
