28. Quiz supraspinatus supraspinatus subscapularis infraspinatus teres minor teres minor

29. Teres major Origin: – Inf angle of scapula Insertion: – Med lip of groove Actions: – Internal rotation and adduction of arm

30. Coracobrachialis Function: flex & adduct the shoulder joint

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

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

35. Levator scapula Origin: – Cervical vertebrae Insertion: – Scapula Action: – Elevation of the scapula

36. Rhomboid major and minor Origin: – Cervical and Thoracic vertebrae Insertion: – Scapula Actions: – Retraction – Elevation

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

38. Pectoralis Minor Origin: – Ribs Insertion: – Coracoid process of scapula Action: – Depression of scapula

40. Pectoralis major Latissimus dorsi

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

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

43. Latissimus Dorsi if humerus is fixed

44. Covering th front and back of the trunk. The pectoralis major and latissimus dorsi both adduct and medially rotate the Humerus.
