23. Classifications of muscles that move the shoulder A. muscles connecting scapula to humerus B. muscles connecting trunk to scapula C. muscles connecting trunk to humerus

24. Short muscles

25. Coracobrachialis Function: flex & adduct the shoulder joint

26. Deltoid Origin: – Clavicle, scapula Insertion: – Deltoid tuberosity of humerus Actions: – Abduction – Anterior deltoid: internal rotation – Posterior deltoid: external rotation

27. B. muscles connecting trunk to scapula 1.Serratus anterior 2.Levator scapula 3.Rhomboid major 4.Rhomboid minor 5.Trapezius 6.Pectoralis minor

28. Serratus Anterior Origin: – Ribs Insertion: – Medial border of scapula Actions: – Protraction and rotation of scapula

29. Trapezius Origin: – Occipital bone of skull, cervical and thoracic vertebrae Insertion: – Clavicle and Scapula Actions: – Elevation – retraction

30. C. muscles connecting trunk to humerus Pectoralis major Latissimus dorsi

31. Pectoralis Major Origin: – Clavicle, sternum, upper ribs Insertion: – Crest of greater tubercle and lat lip Action: – Add, med rotation

32. Latissimus Dorsi Origin: – Vertebrae, sacrum, ilium Insertion: – Medial lip Actions: – Adduction and med rotation of humerus

33. Latissimus Dorsi if humerus is fixed
