Presentation transcript:

Shoulder and Arm Review

Pectoralis Major O: Clavicle, sternum, upper ribs I: Humerus A: Pulls arm anteriorally (across chest), adducts arm

Teres Major O: Scapula I: Humerus A: Adducts arm, rotates arm medial

Teres Minor O: Scapula I: Humerus A: Rotates arm laterally, lift arm backwards

Latissimus Dorsi O: Sacral, thoracic, Lumbar, ribs, ilium I: humerus A: Adduction of the arm, pulls shoulder downward and posterior

Deltoid O: Scapula, clavicle I: Humerus A: Abducts humerus,

Biceps Brachii O: Scapula (x2) I: Radius, Fascia (radioulnar joint) A: Flexes at elbow, rotates hands lateral

Brachialis O: Humerus I: Ulna A: Flexes forearm at elbow

Brachioradialis O: Humerus A: Radius I: Flexes forearm at elbow

Triceps Brachii O: Humerus, scapula, scapula I: Ulna A: Extends forearm at elbow

Flexors Actions: Flex the wrist

Extensors Action: Extends Wrist
