| What is the insertion of Deltoid | Deltoid Tuberosity |
| Origin of Pectoralis Major | Medial half of clavicle, sternum and cartilage of 1 - 6 ribs |
| Insertion of the Pectoralis Major | Crest of greater tubercle of humerus |
| Biceps brachii does what action at the humeroulnar joint | Flex the elbow |
| Biceps brachii does what action at the radioulnar joint | Supinate the forearm |
| Biceps brachii does what action at the glenohumeral joint | Flex the shoulder |
| Origin for short head of biceps brachii | Corachoid process of scapula |
| Origin for long head of biceps brachii | Supraglenoid tubercle of scapula |
| Insertion of Biceps Brachii | Radial tuberosity and bicipital aponeurosis |
| Coracobrachialis does what two actions | Flex the shoulder and adduct the shoulder |
| Origin of the Coracobrachialis | Coracoid process of the scapula |
| Insertion of the Coracobrachialis | Medial surface of mid-humeral shaft |
| Deltoid (Posterior Fibers) is a prime mover for what action at the glenohumeral joint | Extension of the Shoulder |
