| Pectoralis Minor | O-anterior-superior surfaces of ribs 2-4, 2-5, or 3-5, depending on anatomical variation, I-coracoid process of scapula, A-depresses and protracts shoulder; rotates scapula so glenoid cavity moves inferorly; elevates ribs if scapula is stationary |
| Rectus Abdominis | O-superior surface of pubis around symphysis, I-inferior surfaces of costal cartilages (ribs 5-7) and xiphoid process, A- depresses ribs, flexes vertebral column, compresses abdomen |
| Rhomboid Minor | O-spinous processses of vertebrae C7-T1, I-vertebral border of scapula near spine, A-adducts scapula and performs downward rotation |
| Serratus Anterior | O-anterior and superior margins of ribs 1-8 or 1-9, I-anterior surface of vertebral border of scapula, A-protracts shoulder; rotates scapula so glenoid cavity moves superiorly (upward rotation) |

| Trapezius | origin-occipital bone and spinous processes of thoracic vertebrae, insertion-clavicle and scapula, action-elevate, retract, depress, or rotate scapula upward, elevate clavicle, or extend neck |
| Deltoid | Origin-clavicle and scapula, Insertion: humerus, action-abduction at shoulder |
| Rhomboideus Major | origin-spines of upper thoracic vertebrae, insertion: medial border of scapula, action-raises and adducts scapula |

| Triceps Brachii | origin-lateral margin of humerus and tubercle of scapula, insertion-olecranon of ulna, action-extension at elbow and extension and adduction at the shoulder |
| Latissimus Dorsi | origin-spinous processes of inferior thoracic and all lumbar vertebrae, ribs 8-12, and lumbodorsal fascia, insertion-intertubercular groove of the humerus, action-extension, adduction, and medial rotation at shoulder |
| Extensor carpi radialis longus | origin-lateral supracondylar ridge of humerus, insertion-base of second metacarpal bone, action-extension and abduction at wrist |
| Extensor digitorum | origin-lateral epicondyle of humerus, insertion: digits 2-5, action-extends digits 2-5 |

| Flexor Carpi ulnaris | Origin-Medial epicondyle of the humerus, Insertion-5th metacarpal, Action-Flexion and adduction at wrist |
| subscapularis | origin-subscapular fossa of scapula, insertion-lesser tubercle of humerus, action-medial rotation at shoulder |
| Quadratus lumborum | Origin-Iliolumbar ligament and iliac crest, Insertion-Inferior border of twelfth rib and transverse processes of L1-L4, Action-together they depress ribs, alone each side laterally flexes vertebral column |
| Splenius capitis | Origin-Spinous processes of inferior cervical and superior thoracic vertebrae, Insertion-Mastoid process, occipital bone and transverse processes of superior cervical vertebrae, Action-Laterally flexes, rotates, and extends head and neck |
| Iliocostalis lumborum | Origin-sacrum, iliac crest, Insertion-inferior surface of lower 7 rib, Action-extend spine, depress ribs |
| Scalenes | Origin-transverse and costal processes of cervical vertebrae, Insertion-superior surfaces of first two ribs, Action-elevate ribs or flex neck |
